Measuring DevOps

While DevOps Training 

 may 
seem a simple integration of two teams, implementing and getting results 
from newly established DevOps roles and responsibilities is not an easy 
task. Combine an increase in the rate of change with a decrease in the 
magnitude of changes and you have a need to understand subtle changes.

Many organizations struggle to define the business goals, process, and 
organizational constructs to motivate and power team collaboration 
effectively—often due to a multitude of siloed data sources and tools used 
by development, operations, and other stakeholders in a digital business.

This is why it’s vital that you have end-to-end visibility for your 
applications, infrastructure, and digital business as a whole. With 
performance metrics that can be reviewed and shared universally, you can 
monitor your DevOps efforts and prove success at every stage. Leaders 
benefit from knowing that everyone is aligned and moving forward towards 
the same goals. And teammates can collaborate easier and quicker, with 
shared insights.
What you should measure

For your DevOps efforts to be a true success, you have to link and balance 
the goals of faster (speed of delivery), better software (high performing, 
quality software that delivers a good customer experience) to goals for 
innovation and business success. By accessing real-time and historical data 
across the entire stack—from infrastructure and application performance to 
customer experience and business metrics—you can help ensure you are 
meeting all of these objectives.

Here are just a few examples of what you should measure within your DevOps 
environment.

Business Success

Depending on your industry, company maturity, market share, and other 
variables, key performance indicators that your software could potentially 
influence include:

   - Conversion rates
   - Average revenue per user
   - Customer acquisition costs
   - Rate of customer churn
   - Recurring or incremental revenue
   - Renewals and or subscriptions


Customer Experience

It all comes back to the experience of your users. You need to link your 
business to key areas of the customer experience in order to measure how 
well you’re doing. These KPIs could include:

   - Perceived response times of key transactions
   - Frequency of key transactions
   - Number of visits per user/per week
   - User growth rates
   - Funnel/conversion rates
   - Amount of time spent in app
   - A/B test results
   - Customer satisfaction


Application Performance

Catching performance problems before they manifest (and only at scale) 
requires tracking and monitoring a number of database and application 
performance KPIs. Hopefully, your team is already focused on some or all of 
these KPIs:

   - Uptime (availability)
   - App response time
   - Database response time
   - Percentage of transaction time spent in database
   - Resource utilization
   - Database query times

*Speed*

DevOps teams need to focus on the speed of development, delivery, and 
response to issues that occur in production. Metrics to consider for 
helping you track progress and success in this area include:

   - Lead time for changes
   - Frequency of code releases
   - Mean time to resolution


Software Quality

Here are metrics that you can track to help quantify the quality of your 
software’s overall continuous improvement efforts:

   - Deployment success rate
   - App error rates
   - Incident severity
   - Outstanding bugs

[android-developers] Re: Must reboot Lollipop after write to external memory

[Johan Appelgren]

As I understand it you are supposed to notify the media database of any new 
files you add using 
http://developer.android.com/reference/android/media/MediaScannerConnection.html.
 
Android itself will only update the media database automatically on boot. 

/Johan

Den torsdag 13 augusti 2015 kl. 01:09:03 UTC+2 skrev RLScott:

 This is a new problem with Lollipop only.  My app writes to external 
 memory by building a file path name from:

   Environment.getExternalStorageDirectory().getAbsolutePath()

 But when I plug the USB into a desktop computer, the new file does not 
 show up in Explorer.  If I reboot the Lollipop Android tablet and try it 
 again, the file now shows up in Explorer on the desktop computer.  
 Furthermore, if the file already existed, then the version of the file that 
 Explorer sees is the new updated version, just as it should be.  Brand new 
 files do not show up until a reboot of Android.

 Also, this was not a problem with KitKat.  New files written by my app 
 showed up immediately on the USB-connected computer.

 Is there some way, in my app, to force new files to appear immediately to 
 the outside world?  I am writing to the root of the external memory.  This 
 is a side-loaded app, not a Market app, if that makes any difference.  It 
 has been working perfectly for 3 years, until this problem with Lollipop.

[android-developers] Re: Is it possible, that Android kills a service inside an app?

[Johan Appelgren]

What? Whether a Service runs in a separate process or not DOES NOT depend 
on whether you bind to it and/or start it using startService. That is only 
controlled by the process attribute, 
see 
http://developer.android.com/guide/topics/manifest/service-element.html#proc. 

On Friday, December 5, 2014 12:32:33 PM UTC+1, Ashik Vetrivelu wrote:

 It depends on the Service which you have. Service in android is of two 
 types:
 Bound Service and Unbounded Service. Binded Service is what is bound to 
 the activity and it lives as long as activity is running. But unbound 
 service is like a *Separate Process. The Service can still be killed by 
 Android.*To avoid this in the onDestroy() method just call the 
 BroadcastReceiver which launches the service.

 Hey guys,

 let's imagine we have an app with a service and an activity inside. Both 
 components live in a same process, our service is started (in terms of 
 Android) and a user does some interaction with an activity. Eventually our 
 app goes to background. My question is, whether is it possible, under 
 certain conditions (low memory, timeout, etc), that Android kills our 
 started service separately, without killing entire process?

 Thank you,
 Alex

[android-developers] Re: When/where should bindService/unbindService be called

[Johan Appelgren]

Why do you need to start the service at boot? That combined with what you 
write later about starting and stopping the service while your activity is 
running AND binding to it makes no sense to me. You're more likely to get a 
good answer if you explain more what you need the service for.

 I've got a main activity that starts it's own service - if it's not

 by the system on boot.

 Right now I'm doing the bindService() call in onStart() and 
 unbind in onStop().

 The problem is onStart() calls do not match onStop() - no 1:1 correlation.
 Activity life-cycle explains that.

 So where should I put them - onPause() onResume() ???


 Also when I call bindService() - I call startService() - incase it's not 
 already started.
 Is that ok???

 bindService(intent, context, this, Context.BIND_AUTO_CREATE );
 startService( intent );

 If it's already started by the system - it won't create another service - 
 right???

[android-developers] Re: close on minimise application

[Johan Appelgren]

Another activity within your app? If so, just make all of your activities 
set the timestamp in onPause to avoid just that. 

If you with going to another activity mean any activity within any app 
including things like the launcher I don't understand what you want to do.

 It is not right. 

 there shoul be correct way to distinguish minimization from going to 
 another activity.

 take mbanzon's idea - each activity will need to request the password

 You can do it easily by extending an activity with code that handles 
 that, then having all the needed activities inherit from it.

 I have stripped down my code just to find where the problem is and i 
 located it to my httpclient.

 When i run this code iam geting many GC_Concurrent freed.
 if i add a Thread.sleep(1000); then i will ofcourse get less warnings but 
 my guess is that there is still some problem with the code i run.
 Is there a way i could prevent the problem.

 Here is the code:

 Thread c = new Thread() {
 @Override
 public void run() {
 String xml;
  UsernamePasswordCredentials creds = new 
 UsernamePasswordCredentials(username, password); 
  HttpGet httpGet;
  HttpClient httpClient;
  HttpResponse httpResponse;
  HttpEntity httpEntity;
  while (RunThread) {

  try {
  httpClient = HttpClientFactory.getThreadSafeClient();
  httpGet = new HttpGet(http://ipaddress/list?format=xml;);
  httpGet.addHeader(new BasicScheme().authenticate(creds, 
 httpGet));
  httpResponse = httpClient.execute(httpGet);
  httpEntity = httpResponse.getEntity();
  xml = EntityUtils.toString(httpEntity, UTF-8);
  
  
  } catch (Exception e) { 
  e.printStackTrace();
  
  } 
 }
 };
 c.start();
 } 

 And here is the class HttpClientFactory

 public class HttpClientFactory {

 private static DefaultHttpClient client;

 public synchronized static DefaultHttpClient getThreadSafeClient() {
   
 if (client != null)
 return client;
  
 client = new DefaultHttpClient();
 
 ClientConnectionManager mgr = client.getConnectionManager();
 
 HttpParams params = client.getParams();
 params.setIntParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 
 1);
 params.setIntParameter(CoreConnectionPNames.SO_TIMEOUT, 1);
 client = new DefaultHttpClient(
 new ThreadSafeClientConnManager(params,
 mgr.getSchemeRegistry()), params);
   
 return client;
 } 
 }


 Have a made some huge mistage in the code that is causing this issue?

[android-developers] Re: why we prefer Inexact Alarms ?

[Johan Appelgren]

Says why right there in the documentation. 

These alarms are more power-efficient than the strict recurrences supplied 
by setRepeating(int, long, long, PendingIntent), since the system can 
adjust alarms' phase to cause them to fire simultaneously, avoiding waking 
the device from sleep more than necessary.

long, long, android.app.PendingIntent)

[android-developers] Re: Service onDestroy() not being called...

[Johan Appelgren]

In addition to binding to the service, do you use startService? If you do, 
you must also call stopService/stopSelf, just unbinding and calling 
stopForeground is not enough. 

On Thursday, May 2, 2013 9:07:07 PM UTC+2, Larry Meadors wrote:

 I have a bound service that I'm using to play audio. 

 An activity binds to the service in onResume() and sets the service as 
 a foreground service. 

 The onPause() checks to see if the media player on the service is 
 playing, and if it is NOT, calls stopForeground(true), then unbinds 
 (in either case - playing or not). 

 I've got code in the onDestroy with log calls, but while other logs 
 messages from the service show up...it doesn't appear that the 
 onDestroy() is getting called. 

 Am I misunderstanding the lifecycle here, or is there something I can 
 check to see why the service remains running?

Re: [android-developers] Android kills my Thread created by Service

Even if you have a foregrounded service the process might get killed, and 
restarted if the service is configured for it. An example of this is the 
music app on my Galaxy Nexus, it gets killed every now and then if I listen 
to music and use Flipboard or Chrome beta, memory intensive apps.

here http://www.vogella.com/articles/AndroidLiveWallpaper/article.html), as 
a basis for my wallpaper.  It has two activities, LiveWallpaperSettings 
extends PreferenceActivity and MainActivity extends Activity.

I have the following activities (after setting up the stock standard 
wallpaperservice):
activity android:label=@string/livewallpaper_settings
  android:name=com.clock.LiveWallpaperSettings
android:theme=@style/AppTheme
android:exported=true
android:icon=@drawable/clockicon
/activity

activity
android:name=com.clock.MainActivity
android:screenOrientation=sensor
android:label=@string/app_name

android:theme=@android:style/Theme.Light.WallpaperSettings 
intent-filter
action android:name=android.intent.action.MAIN /
category android:name=android.intent.category.LAUNCHER /
/intent-filter
/activity

When I move the filters to the Settings activity, the wallpaper doesn't 
launch from Settings, it crashes with Unfortunately Clock Wallpaper has 
stopped.  
No matter where the intent filter is, when I click on the icon for the 
wallpaper, it toasts Application is not installed.  Just note when I say 
click on the icon I mean the icon in the Apps folder, not the wallpaper 
itself under Settings.  Clicking the wallpaper under settings works 
perfectly with the activities defined as above.

[android-developers] canvas.drawBitmap draws over screen image instead of replacing screen image

[Johan]

I have some strange behaviour when repainting the screen with my live 
wallpaper.  I'm scaling an image and drawing it to the screen, but on each 
draw (as the image is scaled smaller than the previous draw), I can still 
see the previous image below the new image.
How do I clear the previous image out so that only the new scaled image is 
displayed?

This is my code:

private final Runnable mDraw = new Runnable() {
public void run() {
draw();
}
};

void draw() {
SurfaceHolder holder = getSurfaceHolder();
Canvas canvas = null;
try {
canvas = holder.lockCanvas();
if(canvas != null) {
this.paintScreen(canvas);
}
}finally {
if(canvas != null) {
holder.unlockCanvasAndPost(canvas);
}
}
mHandler.removeCallbacks(mDraw);
if (mVisible) {
mHandler.postDelayed(mDraw, 6);
}
}

Every minute my paintSurface function scales a bitmap (image loaded from 
resources), then uses canvas.drawBitmap to put the image on the screen.  As 
I understand from the documentation, holde.lockCanvas()is not supposed to 
contain the image currently on the screen and every pixel has to be 
drawn... this doesn't seem to be the case since the previous pixels are 
obviously under the new pixels.

Thanks,
J

Re: [android-developers] Re: newbie question: Open settings on desktop icon for wallpaper

[Johan]

Yea it seems I bs'd on the fact that it errors when I move the intent 
filters to the Settings activity (or I may have changed something in the 
mean time that makes it work).  Only thing is, now the icon dissipated 
 I can only access the wallpaper via Settings.  If I can figure out how to 
get the wallpaper icon back in the Apps folder I can test if it opens the 
Settings when I click on it.

Always something aint there, lol.

 I'm curious why you have two Activities? I know nothing about live 
 wallpapers, but having one called LiveWallpaperSettings and then one that 
 is actually the one opened in the system Settings sounds ... confusing ...
  

 When I move the filters to the Settings activity, the wallpaper doesn't 
 launch from Settings, it crashes with Unfortunately Clock Wallpaper has 
 stopped.


 You ran this in the debugger? Nothing more from LogCat?
  

 No matter where the intent filter is, when I click on the icon for the 
 wallpaper, it toasts Application is not installed.


 Well, that's definitely weird as the Main + Launcher combo should tell the 
 system to open the specified Activity from the Home Launcher.

 Have you searched the webs for this problem? (like 'wallpaper application 
 not installed ' (note the quotes))

 Have you checked b.android.com for a possible bug?

Re: [android-developers] canvas.drawBitmap draws over screen image instead of replacing screen image

[Johan]

Thanks, yea I set everything in an init function, outside of the main draw 
function (that puts everything on screen).  Learned a lesson there when 
setting too many things I ran out of memory (I set my emulator for only 
512MB to help me make sure I'm aware of memory usage in my app).

Thanks for all your great help!

Re: [android-developers] Re: newbie question: Open settings on desktop icon for wallpaper

[Johan]

getting seriously confusing... Back to basics:

I have a live wallpaper, it has an icon in the Apps folder.  When I click 
on it it toasts me with Application is not Installed.  How do I get it to 
open anything from clicking the icon.
I have the following in the manifest and it does nothing for clicking the 
icon (not even an entry in LogCat) while everything else still works 
perfectly fine:
activity
 android:name=com.clock.MainActivity
 android:screenOrientation=sensor
 android:label=@string/app_name
 android:theme=@android:style/Theme.Light.WallpaperSettings 
 intent-filter
 action android:name=android.intent.action.MAIN /
 category android:name=android.intent.category.LAUNCHER 
/
 /intent-filter
 /activity

Keep in mind it's a live wallpaper activated from Settings, but I would 
like to open the preferences from the icon as a shortcut.

[android-developers] How to lock Live Wallpaper in Landscape?

[Johan Wasserman]

I'm really stuck on this issue and would appreciate any help very much.
I have searched and tried everything I could find on this topic, and still 
have not been able to lock my Live Wallpaper to Landscape. An Earth map 
forms the basis of my wallpaper, so you can see why it needs to be oriented 
to fill the longest axis of the screen side to side.  The wallpaper also 
requires a three image overlay with clipping, so I'm drawing directly to 
the Canvas using .drawBitmap, and setting the .clipPath. For some reason 
using .rotate on the Canvas is ignored. 

Due to the nature of the wallpaper I can only rotate after the image have 
been drawn. Being a live Wallpaper, I cannot use remapCoordinateSystem 
since it only allows one Activity for setting the wallpaper and 
android:screenOrientation=landscape does not work for the same reason 
remapCoordinateSystem does not work. 

I can very easily determine the current orientation, and if the natural 
orientation for the device is portrait (typically phones) or landscape 
(typically tablets) by comparing the orientation with the screen dimensions 
(width  height  rotation = 0 or 180, it's a tablet) Now all I need to do 
is figure a way to lock the screen in the correct orientation.

Is there any other way to ensure the orientation of a Live Wallpaper will 
always be in Landscape mode?

Have you looked at using Multiple APKs?

Wont solve the overhead of managing multiple builds, but at least you wont

 Hi there, 

 I have a real problem when providing different resources for different 
 displays, according to their density. Putting all the needed graphics on 
 the same apk file makes it really big, and most of the graphics will not 
 be used by the device where they are installed never. 

 I have seen that what some developers does is to have an HD separated 
 version of their app, but this implies more development effort and 
 dispersing social promotion of the game (user's ratings, position on the 
 market, social network links, etc.) 

 I think the best approach should be something that keeps the minimal 
 needed resources on the apk, and during the first run of the app takes 
 care of downloading the ones that fits the display of the device. 

 This has some additional difficulties, but I do not want to write a 
 thesis on this, just to ask if someones knows something that does this 
 yet written, before I start reinventing the wheel for my own projects.

Sorry for resurrecting the thread but I was unable to find answer other 
place than the docs. 

You can indeed make isolated database tasts by keeping a reference to your 
IsolatedContext and calling deleteDatabase(name).


private DatabaseManager manager = null;
 private IsolatedContext isolate;
 @Override
 protected void setUp() throws Exception {
 super.setUp();

 if(isolate == null)
 isolate = new IsolatedContext(null, mContext);
 if(manager == null) 
 manager = new DatabaseManager(isolate);
 System.out.println(this.getClass().getSimpleName() +   setting new 
 isolatedcontext);

 }
 @Override
 protected void tearDown() throws Exception {
 super.tearDown();
 isolate.deleteDatabase( databaseName  );

For a lot of apps the life cycle events for activities are enough, no need 
bother with whether the user is in a call or not. And isn't the audio focus 
mechanism enough for most media/music apps unless you need to support API 
level  8? 

If you worry about IMEI, what about Wifi MAC? And what about the phone 
numbers of those you are in a call with? =)

 make and receive calls. On the other hand, very few apps need to know the 
 phone's MEID, which is personally identifiable information. I see no reason 
 why anyone should have to share such sensitive information just to install 
 the latest tower defense game. Permissions with varying degrees of 
 sensitivity or security should not be grouped together.

Re: [android-developers] Non sticky service gets recreated (indefinetly?)

[Johan Appelgren]

So it looks like I'm missing something about how to unbind from a service. 
I thought that calling unbindService with the same ServiceConnection 
instance would be enough. Looking at the output from dumpsys it looks only 
partially unbound or something. I guess this explains why it is restarted. 
How do I completely unbind?

adb shell dumpsys activity services com.example.service

 You can look at the service state with adb shell dumpsys activity 
 services or adb shell dumpsys activity service package_name or 
 service_name.  If your service is listed there, it will show you what its 
 current state is -- what is bound to it, whether it is started, etc.

 As I wrote, my understanding of what you describe is not the behavior I'm 
 seeing with my test app on my Galaxy Nexus with Android 4.1.1 nor the 4.1.1 
 emulator image. After I've unbound from the service, in my test I do this 
 in the activity's onPause, when the app process is killed, it and the 
 service is restarted. Then after that the process and service is killed and 
 restarted every now and then, without starting the activity or any calls to 
 startService or bindService made by any code in my test app. It starts 
 quicker if I start a couple of different games to put some memory pressure 
 on the system.

 Not even stopping the cached process in the Cached processes list stops 
 it, it is restarted a little while after. Only going to the Downloaded list 
 and pressing the Force stop button stops the stop/restart cycle. 

 Perhaps someone could look at my dummy app code and point out what I'm 
 doing wrong. If someone does, I'm sorry for most likely wasting your time.

Re: [android-developers] Non sticky service gets recreated (indefinetly?)

Still occupies some amount of memory though, and the service's onCreate 
might not be cheap. 

Anyways, I guess this is one of those little undocumented things you just 
have to learn. Do not rely on START_NOT_STICKY if you both start and bind 
to a service if you don't want the service to stay around forever as a 
cached process after you've unbound it.

 Binding to a service can only make that service's process as important as 
 the process of the client binding to it.  If the client process is in the

 I'm not sure what this means...?  If you are concerned about the service 
 having too much overhead because you have bound to it and it doesn't need 
 to run just while bound, don't use BIND_AUTO_CREATE.
  

 Anyways, I guess this is one of those little undocumented things you just 
 have to learn. Do not rely on START_NOT_STICKY if you both start and bind 
 to a service if you don't want the service to stay around forever as a 
 cached process after you've unbound it. 


 Honestly I think it is pretty fully documented.  But maybe we have a 
 misunderstanding -- once you unbind from the service, the fact that you had 
 previously bound to it has no further impact on how it is handled, and if 
 its process is killed after that it will not be restarted.

 As long as you are bound to it with BIND_AUTO_CREATE, the system will try 
 to keep it created and if the process is killed while you remain bound to 
 it then it will try to restart it.

 As long as the service is in the started state, the system will try to 
 keep it created/started, and if the process is killed then it will be 
 restarted if it is not sticky.

 The decision about whether to restart the service is if either of those 
 conditions result in it wanting to restart it.

 Again starting and binding are orthogonal to each other.  You just

So START_NOT_STICKY has no effect once I've bound to it even if I unbind? I 
must explicitly use stopService if the service has ever been bound to even 
if there are no more connection?

 I thought START_NOT_STICKY meant that once it gets killed by Android it 
 wont be restarted unless I explicitly start it again. Or does binding to a 
 service override that and make the service sticky?

 I've been testing this on a Galaxy Nexus with stock Android 4.1.1.

[android-developers] Re: HTTP Post works only on port 80 when on mobile network (Galaxy Nexus)

[Johan Appelgren]

Works fine using 3g on my Galaxy Nexus (stock, Android 4.1.1). 

Are you testing using the same carrier and APN settings on the Desire and 
Galaxy Nexus? I've had some issues with a bad carrier proxy that garbled 
non-port 80 traffic, fixed by removing the proxy from APN.

To request a permission you have to use the uses-permission element.

[android-developers] floating window with actionbar

[Johan Bilien]

Hi,

I'm trying to place an activity in a floating window, with an action bar. 
Something similar to this:

http://dl.dropbox.com/u/168185/floating-action-bar.jpg

If I set the theme of my activity to Holo.Light.Dialog, getActionBar() 
returns null.

If I create my own theme, inherit from Holo.Light, and the only change I 
make is to set windowIsFloating to true, the app crashes when accessing the 
action bar, with:

java.lang.IllegalStateException: ActionBarImpl can only be used with a 
compatible window decor layout

[android-developers] Re: When the android id can change

[Johan Appelgren]

If you mean ANDROID_ID then the documentation is pretty clear I think. 

A 64-bit number (as a hex string) that is randomly generated on the 
device's first boot and should remain constant for the lifetime of the 
device. (The value may change if a factory reset is performed on the 
device.)

[android-developers] Re: ICS don't give you a real multitasking.

[Johan Appelgren]

You probably have other apps installed with running services and manifest 
registered broadcast receivers receiving broadcasts pushing the fart apps 
out. As long as there is some memory free for non-service apps their 
processes are cached and reused just fine.

http://developer.android.com/guide/topics/fundamentals/processes-and-threads.html#Lifecycle
 

If your app needs to do things in the background you need to do that work 
in a service, if it is really important work in a foreground service even.

Re: [android-developers] Long running Android service is getting recreated over and over

[Johan Appelgren]

On Thursday, May 10, 2012 1:30:02 AM UTC+2, Dianne Hackborn wrote:

 Yes well there is this meme spread by certain perhaps not unbiased 
 entities that having multitasking at all, I mean doing multitasking like 
 Android, is bad because it is intrinsically battery consuming.  This is of 
 course not true -- if you create a process and it sits there doing nothing, 
 it ain't going to drain your battery.

 The difference between Android and some other platforms is that it does 
 give background code a lot more freedom to do what they want and run when 
 they want, so they have more freedom to do stuff that will drain your 
 battery.  Android does have some safe-guards for this -- it looks for some 
 fairly clear signals like background processes using wake locks or CPU 
 excessively and kills them if this happens, and a UI to help the user 
 understand how applications are using their battery.  It doesn't have such 
 rigid control where there are only X specific types of things that can be 
 done in the background.  It's a different set of trade-offs, but background 
 processes being intrinsically more battery draining is not one of those 
 trade-offs.


Perhaps the Processes and Threads section in the Dev Guide could make it 
more clear that it is up to each app to stop its background threads and 
otherwise ensure they don't do anything when they're not in the foreground 
then? Seems like a fairly common mistake that is difficult for most users 
to understand, they just notice that their phone gets slower over time. 

Which is why, I guess, some games recommend that you force stop all cached 
processes before playing. Not very user friendly.

Re: [android-developers] Re: [Android - developers] Exponential Smoothing on Latitude and Langitude

Hi David, thanks for your respond

The problem's my mistake in a code at the smoothing formula, i use the
wrong value
Anyway, anybody here know about high pass filter?
Thanks

On Mon, Mar 26, 2012 at 5:51 PM, David Griffiths davi...@cordic.com wrote:

 Sorry, my mistake.

 The line

 smoothingCoor[i] = smoothingCoor [i] +alpha * (coor[i] -
 smoothingCoor[i]);

 is correct as it stands. However my comment on your nearing smoothing not
 taking into account the 359 degrees problem is correct.

 Two other problems with the code you have posted: I presume that coor is
 declared as int[] coor = new int[2]; and smoothingCoor as int[]
 smoothingCoor = null;

 So your line smoothingCorr = coor; causes both variables to refer to the
 same array so coor[0] and smoothingCoor[0] always have the same value. The
 other problem is that smoothLat should be smoothingCoor / 1.0E6. Of
 course smoothLat needs to be a double. In fact I can't see why you convert
 the lat/long values into ints - the smoothing agorithm is going to work
 better on floating point numbers.

Re: [android-developers] Re: How I disable GPS when i exit Application

[Johan Appelgren]

If you want to programatically leave (finish) the current activity you can 
use Activity.finish but in most cases you don't have to do anything, the 
user will either leave the current activity using their back or home 
button. Then all you need to do is properly handle the activity lifecycle 
events. In any case Android will take care of managing the process for you.

Re: [android-developers] Re: [Android - developers] Exponential Smoothing on Latitude and Langitude

Hi jinja, thanks for the help
I already tried with the fixed point but it still get me the wrong value
Are there something filtering that we can use to filter latitude and
longitude ? (except kalman filter)
Sory for my bad english

On Fri, Mar 16, 2012 at 12:17 AM, Jinja neiljmar...@gmail.com wrote:

 Hi Concave,

 Okay, I see that you need to keep the values as x1E6 now. However, you are
 still multiplying by 1E6 twice, you only need to do it once. Remove the
 *1E6 from the following lines, so..

 smoothLat = (int) (smoothingCoor [0] * 1E6);
 smoothLongi = (int) (smoothingCoor [1] * 1E6);

 becomes...

 smoothLat = (int) (smoothingCoor [0]);
 smoothLongi = (int) (smoothingCoor [1]);

 Try stepping through your code in the debugger to reveal if your values
 now remain in the correct order of magnitude. Until you've fixed the bug in
 your filtering code I recommend you lock the GPS to a known value e.g.
 insert this at the top of your function...

 newLocation.setLatitude( 49.28214015975995 );
 newLocation.setLongitude( -123.12438011169434 );

 That's Vancouver, use some location you will recognize as correct. Once
 your filter works then you can remove the fixed location and start using
 the GPS values again.

 longitude
 I want to use kalman filter at the first, but after read some paper and
 articles kalman filter is need the value from accelorometer
 Unfortunately my requirement for this application is doesn't use any
 sensor except the gps

 @jinja : Hi thanks for the input, but i think it's the right way to get
 the gps value.
  Because i need the int type value to put it on GeoPoint methode and get
 the GeoPoint to animateTo ().

  int lat = (int) (currentPosition.getLatitude()*1E6);

  So one fix is to use all doubles and remove all of your *1E6. The

[android-developers] Re: [Android - developers] Saving Latitude and Longitude value

[agung wiguna johan]

Update :
I found the solution,but still getting error. Use 2 location variable to
get the previous position before changed :

public void onLocationChanged(Location newLocation) {
prevLocation = currentPosition;
currentPosition = new Location (newLocation);
int lat1 = (int) (currentPosition.getLatitude()*1E6);
int longi1 = (int) (currentPosition.getLongitude()*1E6);
geoPoint = new GeoPoint (lat1, longi1);
showPosition();
mapView.getController().animateTo(geoPoint);
mapView.invalidate();
//Toast.makeText(getBaseContext(), position = + currentPosition,
Toast.LENGTH_LONG).show();
//mapView.postInvalidate();
 //showPosition();
bearing = prevLocation.bearingTo(currentPosition);
   }
};
  }

But when i running the program, it's take long to get the coordinates, and
get force close at the end.
Can somebody help me?

I have an problem here.
I was developing an map application, and it have feature to rotate the map

I know the easiest way to rotate it is, with the Orientation sensor.
But for know, i need to rotate it without sensor.
IMHO it's possible to rotating map with the angle from 2 coordinates
(Before location changed, and after location changed/updated)
But i don't have any idea to save the latitude and longitude before the

Because all pending alarms for an app are removed when it is killed (force

Re: [android-developers] Is it possible to have a static view common to various activities in the application?

[Johan Rydenstam]

It's possible.

Create a Layout you would like to have in A,B and C.

Then use include in each of the layouts.

Example:

include android:id=@+id/header
layout=@layout/header
android:layout_height=wrap_content
android:layout_width=fill_parent/

Re: [android-developers] Need Help in Options Menu

How do you know what menu you want?

You could start the activity by passing in some extra parameter with the intent.

  public boolean onCreateOptionsMenu(Menu menu) {
 MenuInflater inflater = getMenuInflater();
if(getIntent.getBooleanExtra(second_menu,true))
 inflater.inflate(R.menu.optionsmenu, menu);
else
inflater.inflate(R.meny.optonsSecondMenu, menu);
 return true;

Re: [android-developers] OutOfMemoryError

[Johan Rydenstam]

Are you using different resources for the tablet (like hdpi?).

I would check for memory leaks. There are tools you can use for this ( Eclipse 
memory analyzer)

In this case it is impossible to open up for URLs. And the service
needs to access

How can this be done? Are there any specific subnets for this?

[android-developers] Android 3.1 and Bluetooth HID

[Johan Zander]

The Android 3.1 Platform Highlights [1] states:
To make the platform even better for gaming, Android 3.1 adds support
for most PC joysticks and gamepads that are connected over USB or
Bluetooth HID.

Has anyone out there successfully got an Android application to
communicate with a Bluetooth HID device? In that case, how? Is it the
USB host API [2] that should be used?
We've tried with a Motorola XOOM 3.1 without any success, but there
are many threads reporting problems with the Xoom and USB host API.

[android-developers] Re: SE LiveView SDK Template app

[Johan Abramsson]

Basically, you can rename your classes and packages as you want to.
What you need to keep intact is the interface package, i.e.
com.sonyericsson.extras.liveview.IPluginServiceCallbackV1/
IPluginService

And you need to keep track of your naming of the intents in the
manifest and res/values/strings.xml.

Manifest: application-service-intent-filter-action-name needs to
correspond to res/values/strings.xml-intent_service
Manifest: application-application-intent-filter-action-name needs
to correspon to res/values/strings.xml-intent_preferences

Renaming the other packages and names also need to be defined
correctly in the manifest. Easiest way to get that right is to check
the current manifest setup of the template-project or the other
examples, and change the manifest accordingly. Some things will
hopefully be corrected for you by the built-in functionality of your
IDE, e.g. Eclipse.

 Hi,

 I would like to develop apps that uses Sony Ericsson's LiveView
 device. I'm new to Android and Java, so my question my seem stupid. My
 experience is mainly C/C++ with Microsoft's MFC and Nokia's Qt, but
 Java seems to be not too far from C++. I managed to make some changes
 to the Sandbox example app which is included with the LiveView SDK,
 and it behave like I expected, so it seems like have understood at
 least a bit of LiveView, Android and Java. Now, here's my stupid
 question.

 In Eclipse, I import the template app included with the SDK, and call
 it something else. Now, what changes should I do to it in terms of
 names of files, names of packages, etc?

 Everywhere I saw the name Template, I changed it to my own app name,
 but that leaves a lot of package names beginning with
 com.sonyericsson... and ending with my app name. I guess I should
 change the beginning of some package names, but probably not all.
 Which ones should I change?

 It would have been nice if the template files had more detaild
 instruction comments, like
 // TODO: change the next next line to the format
 myTopDomain.myDomain.MyExtraHierachy.MyAppname

 I used appXplore to check other LiveView plugins from Market, just to
 see how others did. And it's a mix. Some have kept  com.sony.ericsson
 in the beginning of their package names, process names, and preference
 activities, and some have changed to their own. (I know that some of
 the LiveView plugins in Marked are developed by Sony Ericsson, so it's
 natural that they kept com.sonyericsson... but some non-sony-ericsson
 also kept it).

 So, it seems like I'm not the only one who need guidence.It would be
 nice if Sony Ericsson presented guidlines on how they expect people to
 do. If they don't, it would be nice if someone else wrote detailed
 instructions.

 Should the following keep their names (including com.sonyericsson...)
 myProjName/src/com.sonyericsson.extras.liveview
 myProjName/src/com.sonyericsson.extras.liveview.plugins

 Should I change the following:
 myProjName/src/com.sonyericsson.extras.liveview.plugins.template
 to for example
 myProjName/src/
 myTopDomain.myDomain.myAppName.liveview.plugins.myAppName

 I tried that,and updated the manifest etc, but I didn't get it to
 work. Should I have done something else?

 It would have been really nice for beginners like me with specific
 TODO: comments saying exactly what to do.

 Thanks in advance

[android-developers] Re: Need ideas on encrypting h.264 videos on Android

[Johan Lindquist]

Interesting idea, but a couple if questions come to my mind - what
kind of file descriptor is OUT FD in this case?  Since it would have
to be writable from one end and readable from the other it would have
to be some sort of pipe?

I ask because we are only passing the descriptor to the MediaPlayer
which would then be accessed independently of any InputStream/
RandomAccess file that created it, giving us little chance to override
any of these operations.  Bear with me if I am missing the obvious
here though.

Also, for what it is worth, FD is final, making it hard to override.

Ideally, it would be open up a variety of options if the media player
allowed for data to be provided as part of a set of callbacks,
removing the reliance on support for various transports in the native
layer itself.

Cheers,

Johan

 Peter, looking at various available APIs, it seems that you have 1
 choice (maybe 2):

 1) to decrypt the video into a temporary local file and prepare
 MediaPlayer (or VideoView) with URI to this temp file.
 It obviously makes you vulnerable to attack, between creation and
 deletion of said file.

 possible 2) Extend FileDescriptor class so that it's IN file
 descriptor points at encrypted video file
 FD.sync() of your extended FD causes read +  decrypt + write to OUT FD
 (which is what MediaPlayer reads from) of some chunk of the encrypted
 file. The resulting amount of decrypted bytes should be big enough to
 keep the player occupied. Please also mind that this will all depend
 on the 'power' of host hardware.

 Your sync() method should be overriding parts of file that OUT FD
 points to, that have been consumed already by the Player with some
 random gibberish. You will need to use RandomAccessFile to create the
 OUT FD and keep track of its offset for erasing and for playing.

 Good Luck!

Hi,
Judging from the specs when I read them, the pressure sensor will
fulfill your requirements when it comes to measurement frequency and
the altitude range. I do however not think that it has the resolution
of 10 centimeters in altitude.

Kind regards

 I would like to use it for programming the altimeter/vario for

 Perfect sensitivity would be measured every second, sensitivity of 10
 centimeters altimeter and altitude range of 0-3500 m above sea level.

[android-developers] Discrepancy between streaming data over localhost vs WIFI network interfaces on 3.0

[Johan Lindquist]

Hi all,

I have written a proxy server which takes a remote HLS video and
simply streams the content to the MediaPlayer (running on a Galaxy Tab
10.1 - Android 3.0.1).Whatever request the MediaPlayer makes, the
proxy mirrors onto a remote web server.

I have noticed that the MediaPlayer will not play the video correctly
(it stops, as if buffering) when using the localhost (http://localhost
URL) but while binding the server to the WIFI interface (http://
172.30.17.X URL) it happily plays it.

Has anyone ever seen a discrepancy like this when using the different
interfaces?  Any ideas on how to resolve this?  Binding to the WIFI
address is of course OK in many cases but makes things a little tricky
when on 3G.  Any suggestions and or comments on this would be
appreciated!

Cheers,

Johan

Hi Android Developers,
The second version of the Sony Ericsson EDK has been released today.
The news is that you can now create extension applications for the
Musicplayer on Sony Ericsson Android phones as well.
Or to be more exact – application that can hook in to the infinite key
of the music player.
It can, like before, also be used to create Timescape extensions for
all Sony Ericsson Android phones.
For further information please check this link:

 Hi there,

 Thanks for downloading theEDK, we hope you will find it useful. In
 our 2011 Android products the deep integration of Timescape was
 changed so that it is a standalone app, and in the same time we
 decided to specialise Timescape a little bit more also. Therefore, the
 email extensions were not part of this Timescape version. However, if
 you or any other developer would like to develop an extension for
 email client extensions, you are welcome!

 Feel free to submit any further questions about theEDKhere.

[android-developers] Re: Sony Ericsson EDK for Timescape

[Johan Abramsson]

Hi there,

Thanks for downloading the EDK, we hope you will find it useful. In
our 2011 Android products the deep integration of Timescape was
changed so that it is a standalone app, and in the same time we
decided to specialise Timescape a little bit more also. Therefore, the
email extensions were not part of this Timescape version. However, if
you or any other developer would like to develop an extension for
email client extensions, you are welcome!

Feel free to submit any further questions about the EDK here.

Best regards,
Johan

 Hi Johan,
 I just downloaded the EDK today and played around with the RSS extension,
 looks really good!
 I was wondering, how come Sony Ericsson didn't include an email extension
 like they did with the 2010 Timescape?

 Really nice article. It is great to see development related tutorials
 fromSonyEricssonlately.

 But I would like to ask about font scaling. I myself am visually
 impaired since birth (but still a software developer) and I know many
 people who wish to use Android devices but cannot do that comfortably
 because there is no font scaling built into the core of Android. This
 is also bad for people over 50 who do not have a perfect vision
 anymore.

 There is a 2 years old feature request on Android issue tracker, but
 it seems abandoned by 
 developers:http://code.google.com/p/android/issues/detail?id=4547

 Of course, each developer can make the fonts scalable, but they do so
 not often. The worst is that the basic phone functions (menu,
 contacts, SMS, mail) have too tiny texts.
 I myself am looking forward to buy SonyEricsson Neo, but I am afraid I
 won't be able to use it comfortably, I need a little bit bigger fonts
 everywhere and I would like avoid rooting the device just to do some
 hacky font replacement which would look ugly anyway.

 So if someone could bringSonyEricsson'sattention and ask them to
 develop more accessible software (just a basic home screen, contacts,
 SMS, menus), I guess,SonyEricssonwould get buyers from all the 50
 old people range + some bunch of people with impaired vision.

 I promise you,SonyEricsson: on the day you develop and release some
 software update which allows to scale fonts bigger on aSonyEricsson
 Neo phone, I'll buy it. For now I'll just read articles about Android
 development and use SDK/VirtualBox Android emulators.

 Please,SonyEricsson(and other developers, too), give a helping hand
 to visually impaired and not-so-young people.

 Good luck to all developers,
 Martin
 and some other visually impaired people.

[android-developers] How to Adapt your apps for the new LiveSound™ hi-fi headset and the LiveDock™ multimedia station

[Johan Abramsson]

Sony Ericsson has announced the LiveSound™ hi-fi headset and the
LiveDock™ multimedia station. The LiveSound™ hi-fi headset is also the
first headset to support the new LiveKey™ feature which is a button on
the headset where you as developer can control your application.  You
can download the tutorial and sample code here:
http://developer.sonyericsson.com/wportal/devworld/technology/smart-extras/livekey?cc=gblc=en
The LiveDock™ multimedia station is a smart, new docking station for
your phone which will launch any application you have set in the
LiveWare™ manager application. As developer you can adapt your
application to start as soon you connect the phone to LiveDock™.  You
can download the tutorial and sample code here:

 I am developing a app which use the camera on Sony Xperia Neo

 which support Camera Zooming.

 When I tried to check the Zoom Support using

 wrong.

 I then try to check the HashMap in the Camera.parameter looking for
 the value of zoom-supported , and the value is also false.
 Besides, zoom=0, max-zoom

 Therefore, my app cannot control the zooming of the Camera preview
 because of this.

 I wonder why it happens ? is it because the Sony's SDK does not return
 the correct value ?

 The same code running on HTC wildfire  Nexus One do not have problem.

 Thanks in advanced for any help ..

[android-developers] DownloadManager lack of functionality. Bug or intentional limitation?

[Johan Alva]

Hi,

In gingerbread the public download api doesn't take care of duplicate
filenames and also no download directory is automatically created. Are
these behaviours intentional or just bugs?

As it is now the application requesting a download must itself make
sure:
1. That a download directory exists (and if not, create one)
2. That the wanted filename for the file to be downloaded doesn't
already exist (and if it exists, change filename)

So, does anyone know if there is a reason why the application needs to
handle these two things instead of the DownloadManager

big thanks!

[android-developers] Re: Orientation Problem in Camera.

In the firmware 2.0.A.504 of Xperia X10 there seems to have sneaked in
a problem regarding usage of the undocumented orientation
parameters. That parameter is not correctly implemented. Work is
ongoing to solve this issue, (although it is not documented in the
android vanilla doc's) however I recommend to lock the activity in a
orientation mode in the mean time.

 
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

 If you're not targeting Cupcake, a variation on Aleksandr's suggestion might
 work.: put all your images in -hdpi directories and let the system scale
 them for other densities. It generally does a better job downscaling than
 upscaling, for obvious reasons, so the results might be acceptable. Note
 that I haven't tried this, but it seems plausible.

[android-developers] Optimal packaging of image app for various screen resolutions

[Johan]

Hi there,

I'm working on an app which displays various images. I want to
optimize this for the various screen resolutions. The MultiResolution
(1) tutorial uses many resource qualifiers in the res folder to
display the appropriate images for the various device resolutions, but
how do you package this? I don't want to ship the images for all
devices (or do I?). I want to keep the download size as small as
possible, so I only want to package the ones for that particular
screen resolution. Or, should I forget packaging images and put the
images on-line somewhere?

Any opinions on this subject would be appreciated

Hi Sterling,

Thanks for your answer (and I added a vote to your feature request
since it perfectly describes the trouble at hand ;-).

So you agree that with an image-heavy app splitting up into various
apk's is good practice, but there currently aren't any good tools for
it? Hmm... maybe I'll have write my own build scripts with something
like AndroidAnt (http://code.google.com/p/autoandroid/wiki/AndroidAnt)
or does anybody have another good build-your-own-android-build-script
alternative?

Cheers,

Johan

 Unfortunately, there's no way to avoid duplication with the current

 Long ago, I submitted a feature request to address this issue 
 (http://code.google.com/p/android/issues/detail?id=5207), but right now it
 only has 2 stars and hasn't even been acknowledged by the platform team.

[android-developers] Re: Capture image with Intent

[Johan Abramsson]

Hi,
We aer aware of this problem.
Try this approach to work around:
To get the full size picture you can do like this:

 private void launchStillPictCamera(){
  Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

try {
startActivityForResult(intent, 42);
} catch (ActivityNotFoundException e) {
//Do nothing for now
}


 }

and upon activity result:
 @Override
 protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
  super.onActivityResult(requestCode, resultCode, data);

  switch (resultCode) {
  case RESULT_OK:
   if (requestCode == 42) {
String photoPath = null;

   if(data!=null  data.getData()!=null) {
Uri photoUri = data.getData();
 String[] projection =
{ MediaStore.Images.ImageColumns.DATA };
 Cursor c = managedQuery(photoUri, projection,
null, null, null);
 if (c!=null  c.moveToFirst()) {
  photoPath = c.getString(0);
 }
 Log.v(PhotoPath, photoPath);

//And now the photo can be copied or moved as of your own choice using
output/input streams of your own choice
   }

   } else {
System.out.println(Yada request code NOK);
   }
   break;
  default:
   System.out.println(Result NOK);
  }

         }
     }

 }

 And layout file is as follows:

 ?xml version=1.0 encoding=utf-8?
 RelativeLayout xmlns:android=http://schemas.android.com/apk/res/
 android
                                 android:id=@+id/Widget
                                 android:layout_width=fill_parent
                                 android:layout_height=fill_parent
                                 android:gravity=center
         AnalogClock android:saveEnabled=true android:id=@+id/AnalogClock
 android:layout_width=wrap_content
 android:layout_height=wrap_content android:dial=@drawable/
 widgetdial android:hand_hour=@drawable/widgethour
 android:hand_minute=@drawable/widgetminute/
 /RelativeLayout

 Could you please advise what can cause such problem.

 Thanks,
 Alexander

[android-developers] How to optimize an image app for various devices and screen resolutions

[Johan]

Hi there,

I'm working on an app which displays various images. I want to
optimize this for the various screen resolutions. The MultiResolution
(1) tutorial uses many resource qualifiers in the res folder to
display the appropriate images for the various device resolutions, but
how do you package this? I don't want to ship the images for all
devices (or do I?). I want to keep the download size as small as
possibel, so I only want to package the ones for that particular
screen resolution. Or, should I forget packaging images and put the
images on-line somewhere?

Any opinions on this subject would be appreciated

[android-developers] Sony Ericsson LiveView™ micro display SDK upgrade is released

[Johan Abramsson]

Due to a design error in the LiveView SDK, there is a risk that the
plug-in icon of one installed plug-in can be overwritten by another
installed plug-in. I.e. the same icon file is used on the SD card. The
design error has been fixed and published on Sony Ericsson Developer
World.

Please go to 
http://developer.sonyericsson.com/wportal/devworld/downloads/download/liveviewmicrodisplaysdk
to get the latest version of the SDK.

Best regards
  /Johan
