OK. So do some custom drawing. Review the MavView and Overlay classes and
their draw() methods. The Canvas class, and other related classes, will
also be helpful.

sTemp = String.format(%.2f m, 2 * rest);

displays in the correct locale. How can I fix the input fields?

 Some GPS chipsets allow a RTCM correction stream as input and apply 
 correction themselves. Is this possible to send data to the GPS ? And 
 to read the GPS chipset model (to evaluate if it allows RTCM) ? 

 Thank you for your help.

[android-developers] Android developer registration with Neteller

[Balint]

Hello everyone,

I tried to register as an android developer with my Neteller card, but
Google asks for the Bank code and my bank account number. I am
registered with a local bank now, where I have these data, but I tried
to add my Neteller card, so the money I earn would be transferred to
that card from next month. How am I supposed to register/add this
card?

I contacted Neteller and they told me to contact Google...

This was my question:

I have created a Neteller account and have just activated my Neteller
card. I want to register as an Android developer with this card and
google asks for the bank code of your bank (Conister Bank?) and my
account number. Can you help me?

This is their bland answer:

WIth regards to your inquiry, I asked my supervisor. I found that you
need to put just your card information as usual credit card for
purchase something.  Therefore it should not be like that.  Please ask
the company and explain that.

I don't even know if that is Conister Bank or Barclays Bank.

Thanks,
Balint

Re: [android-developers] Re: Android bluetooth api connect to multiple devices at the same time

[Ali Rezaeian]

I am using the Android Bluetooth Chat Sample, and I was wondering how and 
where I should add codes to able to connect to multiple devices?

On Wednesday, December 22, 2010 8:57:53 PM UTC-6, Kristopher Micinski wrote:

 Many people have this problem, this implements a Bluetooth Piconet,
 this is why this is using seven different UUIDs for the Bluetooth
 socket.
 I went through this example and saw how it is implemented, it is
 similar to how we implement this client/server functionality in a few
 of our applications in our research.
 I believe the key to getting this to work is inthe mUuid list.

 Take a close look at what this is doing?

 for (int i = 0; i  Connection.MAX_SUPPORTED  myBSock ==
 null; i++) {
 for (int j = 0; j  3  myBSock == null; j++) {
 myBSock = getConnectedSocket(myBtServer, mUuid.get(i));
 if (myBSock == null) {
 try {
 Thread.sleep(200);
 } catch (InterruptedException e) {
 Log.e(TAG, InterruptedException in connect, 
 e);
 }
 }
 }
 }

 What this code does is looks to connect to the device, but how does it
 do so? It tries the socket multiple times, using multiple UUIDs for
 the session. In essence it means that we can use UUID only *once*. So
 instead this application implements using seven UUIDs, then the server
 listens and accepts each UUID on the server side, this is what is done
 with the following code:

 for (int i = 0; i  Connection.MAX_SUPPORTED 
 maxConnections  0; i++) {
 BluetoothServerSocket myServerSocket = mBtAdapter

 .listenUsingRfcommWithServiceRecord(srcApp, mUuid.get(i));
 BluetoothSocket myBSock = myServerSocket.accept();
 myServerSocket.close(); // Close the socket now that 
 the
 // connection has been made.

 String address = 
 myBSock.getRemoteDevice().getAddress();

 mBtSockets.put(address, myBSock);
 mBtDeviceAddresses.add(address);
 Thread mBtStreamWatcherThread = new Thread(new
 BtStreamWatcher(address));
 mBtStreamWatcherThread.start();
 mBtStreamWatcherThreads.put(address,
 mBtStreamWatcherThread);
 maxConnections = maxConnections - 1;
 if (mCallback != null) {
 mCallback.incomingConnection(address);
 }
 }

 Now, on the client side of things what is done? The client does not
 know how many active connections the server currently has. If we have
 some agreed upon order that the clients must use we can simply use
 this, however, in our case, we simply just try *each UUID* in sequence
 until we find the right one.

 Hopefully this helps you, and everyone else who has questions about
 this problem, feel free to email me with problems you have.

 Short version:
   -- Use multiple UUIDs, you can only use one at once. So define seven
 (max for piconet usage) and try each one until you find the right one.

  I looked at  the FBTClickLinkCompete'source,
   for (int i = 0; i  Connection.MAX_SUPPORTED  myBSock == null; i++) {
  for (int j = 0; j  3  myBSock == null; j++) {
  myBSock = getConnectedSocket(myBtServer,

  }
  }
  }
  This code fragment shows a client  that trys to connect the server... 
 The sample of SDK(BluetoothChat) used same code except
  for (int i = 0; i  Connection.MAX_SUPPORTED  myBSock == null; i++) {
  for (int j = 0; j  3  myBSock == null; j++) { 
  I don't understand why?   what'more, it can't connect to multiple

[android-developers] Using: Picture.createFromStream gets stuck - does not return new picture

[Asi Mugrabi]

Anybody could use Picture.createFromStream successfully?
When using static method Picture.createFromStream (static Picture 
createFromStream (InputStream stream))on a file created by writeToStream, 
it does not return new picture(actually does not return at all).

Here is the snapshot of the code
public boolean streamPicture(Picture p)
{
if(_outStream == null)
return false;
else {
p.writeToStream(_outStream);
if(fileOutputStream != null ) {
p.writeToStream(fileOutputStream); // retrieved by 
fileOutputStream = new FileOutputStream(/data/picture.nubo) ;
try {
fileOutputStream.flush();
fileOutputStream.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

try {
Picture p_check = Picture.createFromStream(new 
FileInputStream(/data/picture)); //*** gets stuck here
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return true;
}
}
}

The code gets stuck at ***

1. I checked and saw that the file /data/picture is created before line ***.
2. Picture p is retrieved by capturePicture() in webview (I did not use 
startRecording)

Any ideas anybody?

Thanks,
Asi

[android-developers] Using MonkeyRunner to test apps on several emulators

[Alberto Giannetto]

Hi there,

I am writing a set of scripts that drive an app on several emulators 
simultaneously. My main script spawns several threads, each of which runs 
an instance of MonkeyRunner and I am using a Monkey script to interact with 
the app and using a loop calling repeatedly 

device.getProperty('am.current.comp.class') 

to identify the class that originates the current activity. This is to 
react differently by performing different actions depending on the activity 
being displayed.
This seems to work reasonably well for one emulator, but the moment I have 
two or more emulators running at the same time, the call to 
device.getProperty('am.current.comp.class') seems to get stuck on a class 
that displayed an earlier activity.
Any idea why that might be? Note that I am connecting to the correct 
emulator by using 

device = MonkeyRunner.waitForConnection(deviceId=emulatorName)

where emulatorName starts off tipically at 'emulator-5554'.

Alternatively, is there a more reliable way to achieve this with a sort of 
monitoring app that sits in the emulator and, somehow (not sure how), 
communicates with the driving script?

Many thanks,
Alberto

[android-developers] Altering UserAgent for the Emulator

[apoxy]

First, I'm not a developer, I'm QA. Part of my role in QA is to find some 
answers to questions which apparently not many are asking.
Can I change the user agent of the Emulator to match that of an actual 
device? 
By using about:debug I can change to desktop, iphone, ipad, froyo, and 
android, however using just android results in generic build/unknown
 
My website and app contain an error with some Motorola devices (specifcally 
the Droid Razr and Photon) where users are unable to submit a search within 
a search field (the search field is jquery or jscript, whatever one of the 
newest ones is). This ONLY happens, so far, on these devices and I am able 
to reproduce using the emulator for these devices (other emulated devices 
function ok).
 
So, either we need to fix the issue (which is preferred but unknown as to 
how), or we have to add useragents for every device that ends up broken 
(which seems to trend towards Motorola devices).
 
So back to the question(s):
Can I change the user agent of the Emulator to match that of an actual 
device? This would assist immensly for fix verification
How can I reliably find the user agent of devices? Currently the only place 
I've found, though it uses WURFL (and I'm not sure howe correct it is), is:

[android-developers] Impact of Android Customizations by device manufacturers

[Deepak]

Hi all,

I am trying to write an android application that uses several of the
android apis(like policy manager, package manager, wifi apis etc).

The concern i have is, android being open, manufacturers/carriers are
free to take any specific version of android as their start point and
customize the same and ship it with the device.

Note:Please excuse me if this post is in anyway a repeat of earlier
posts on the same/similar topic. In such a case, appreciate anyone
sharing the earlier post.

Few things that bother me are:

 - Does android enforce/require manufacturers/carriers to retain the
default apis and only over-ride/customize the look-and-feel?
 - even if manufacturers change the implementation/behavior of the
basic apis that comes from android, do they adhere to the interfaces
so that my code doesnt break?
- how do i ensure/test that my code works on all of the android
devices since there is a possibility that one or more customizations
could break my whole application?

I know these are some naive questions for many of you who may have
been on android for a while, but any pointers in this regard would be
of immense help.

Any other information in general w.r.t cross version, cross device
incompatibilities and strategies to deal with them would be very
helpful.

Thanks a lot in advance.

Regards,
Deepak

[android-developers] Re: AsyncTask in Android 4.0

[Jerry Stralko]

I'm trying to update my codebase to use ThreadPoolExecutor, but I found 
this to be odd:

/** @hide */
public static void setDefaultExecutor(Executor exec) {
sDefaultExecutor = exec;
}

So why is this method hidden?  So I can't globally set the DefaultExecutor 
to ThreadPool?  Or is this subject to change that is why its marked as 
@hide?

Currently the Solution I came up with is subclass the AsyncTask:

public abstract class ThreadPoolAsyncTaskParams, Progress, Result 
extendsAsyncTaskParams, Progress, Result {


 public void executeOnThreadPool(Params...params) {

/*

 * This is a helper method to allow ICS AsyncTask to run in a thread pool, 

 * without break API compatability with pre-ICS devices.

 * If you don't want a threadpool use the default AsyncTask since that is 
the 

 * default for ICS.  If you don't want a threadpool for pre-ICS (API level 
 13) 

 * then you need to write your own AsyncTask. Use the AsyncTask.java source 
as a starting point.

 */

 if (Build.VERSION.SDK_INT = Build.VERSION_CODES.ICE_CREAM_SANDWICH) {

this.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, params);

} else {

this.execute(params);

}

}

}

I'm just wondering if this is the best solution?  That way I can use a 
ThreadPoolAsyncTask if I really want Parallel task and use AsyncTask 
directly if I want Serial execution.

Am I understanding this correctly?

Thanks,  

On Friday, April 20, 2012 3:16:35 PM UTC-4, Nathan wrote:

 Still adjusting to the changes in Android 4.0 regarding AsyncTask. 

 If I understand right, the default behavior of execute is changing to one 
 single thread pool with only one thread? With the reason cited that 
 programmers are not capable of handling a bigger threadpool (I'm 
 paraphrasing). 

 Does that mean, that absent some code changes, all asynctasks inside a 
 process will only happen sequentially?  

 So therefore, if I have a service running DownloadDictionaryTask in the 
 background, and the user chooses a menu item that starts 
 CheckDiskSpaceTask, the progress bar will cycle without any progress 
 because the task never makes progress?

 A user and I could briefly reproduce a situation where, as far as I could 
 tell, no asynctasks were running, yet my AsyncTask would not even start. In 
 this case, I couldn't even get one thread. Alas, I cannot reproduce that 
 situation, which appeared to fix itself without any code changes. 

 But in any case, this isn't really acceptable to have only one asynctask 
 task run at once. But there is no central way to control that behavior, is 
 there? I would have to replace 83 instances of task.execute with 
 task.executeonExecutor. Since the above method is only available in SDK11, 
 this isn't a one line change - it's more like 10-20 lines of code with 
 reflection, and some extensive testing. 

 In my opinion, this a deplorable punishment for those developers who have 
 dutifully followed the AsyncTask pattern, which, to this day, the Android 
 platform has encouraged. 

 Or perhaps I am reading this wrong. Maybe all DownloadDictionaryTasks 
 share one pool, and all CheckDiskSpaceTasks share another pool. In that 
 case, the rule is that only one task *of the same concrete type* can run at 
 once. This rule, I can probably live with, as I've used my own threading 
 pools for tasks that are truly data parallel.  

 Can anyone enlighten me more?

 Nathan

[android-developers] AlarmManager doesn't start service

[eMu]

I have a big problem with my app for serveral days now. I appologize
if my english is not so native in advance. I implemented an
AlarmManager to give the user of my app the option to start a certain
service at any time of the current or the next day. So e.g. the user
might choose to set the time for my service to tomorrow at 08:00 a.m.
and then starts the service.

The alarm manager should now wait the calculated time from now till
the chosen time (i calculated the time also manually and it is
correct!) and then start the service. My problem now is that sometimes
the alarmmanager is starting my service and somtimes not. It seems
that if it has to wait for lets say more than 4 hours it is not
working any more and my service is not called. I have set all
neccessary permission otherwise it would not work at all. You can have
a look at the code of the alarmmanager below:

someIntent = new Intent(START_SERVICE);
AlarmManager alarams ;

alarmIntent = PendingIntent.getBroadcast(MainActivity.this, 0,
someIntent, PendingIntent.FLAG_CANCEL_CURRENT);
alarams = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarams.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+delay,
alarmIntent);
The broadcast receiver is implemented like this (and it is
registered!):

alarmReceiver = new BroadcastReceiver() {

@Override
public void onReceive(Context context, Intent intent) {

Intent myIntent = new Intent(MainActivity.this,
MyService.class);
startService(myIntent);
}
};

I read smth. about the WAKE_LOCK and that my Service might not be
called anymore before the phone goes into sleep mode after the
broadcast receiver is being called. Can this be the reason? I really
hope you can help me

Best Regards
eMu

[android-developers] Re: AsyncTask in Android 4.0

[Jerry Stralko]

On Friday, April 20, 2012 3:16:35 PM UTC-4, Nathan wrote:

 Still adjusting to the changes in Android 4.0 regarding AsyncTask. 

 If I understand right, the default behavior of execute is changing to one 
 single thread pool with only one thread? With the reason cited that 
 programmers are not capable of handling a bigger threadpool (I'm 
 paraphrasing). 

  
I'm also trying to figuring out why setDefaultExecutor is hide but public?

/** @hide */
public static void setDefaultExecutor(Executor exec) {
sDefaultExecutor = exec;
}

Is this because it is subject to change and non-framework clients (i.e. 
third party dev) should be use this? For my app I wanted to globally change 
the Executor to ThreadPool, but that doesn't seem possible. 

So what I'm currently doing is subclass the AsyncTask like so:

public abstract class ThreadPoolAsyncTaskParams, Progress, Result 
extendsAsyncTaskParams, Progress, Result {

/*

 * This is a helper method to allow ICS AsyncTask to run in a thread pool, 

 * without break API compatability with pre-ICS devices.

 * If you don't want a threadpool use the default AsyncTask since that is 
the 

 * default for ICS.  If you don't want a threadpool for pre-ICS (API level 
 13) 

 * then you need to wrote your own AsyncTask. Use the AsyncTask.java as a 
good starting point.

 */

public void executeOnThreadPool(Params...params) {

if (Build.VERSION.SDK_INT = Build.VERSION_CODES.ICE_CREAM_SANDWICH) {

this.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, params);

} else {

this.execute(params);

}

}

}

I'm just wondering is this is a good solution?  This way I can use 
ThreadPoolAsyncTask for task that can run in parallel and don't have any 
implicit dependence on other tasks. And use AsyncTask directly if i want 
them to run in serial.

Thanks,

[android-developers] Android 2.2 Problem about Video Scaling

[Deniz Tuna]

In my application I need to show videos in some boxes with different 
dimensions. So I am currently giving some dimension to my videoview however 
videos that I gave could not scale into those regions. They are just cut 
off from those dimensions. I already tried to implement my own onMeasure 
method but It didn't help me too. So anyone knows how to scale videos for 
different boxes?

Thanks in advance.

[android-developers] Storing data on the SD card in Froyo - files deleted when upgrading revisited

[dakin80]

I'm using:

android.content.ContextWrapper.getExternalFilesDir(null)

as the location to store my app's files.

The app is designed to run on API versions 8 (Android 2.2) onwards.

Whilst testing on the emulator running 2.2 I find that if I upgrade the 
application then it deletes the existing files in this location.

This has been discussed before:

https://groups.google.com/d/topic/android-developers/to1AsfE-Et8/discussion

Dianne Hackborn gave details of the patch which was made to Froyo, 
presumably in a subsequent build.

According to:

http://developer.android.com/resources/dashboard/platform-versions.html

2.2 still comprises about 20% of devices so I'd like to support it but I 
don't want to risk deleting users' data which in my app is user generated 
and might not be recoverable. The Platform Versions report doesn't break 
the figures down by build number so it's difficult to know how many users 
could be affected by this.

Can anyone help? Am I worrying unnecessarily? Were many 2.2 devices 
released with this bug still in? If the emulator had been patched I might 
not have spotted the problem but the fact that it isn't makes me reluctant 
to ignore it.

I know I could sidestep the issue by simply choosing my own directory but 
I'd like to follow best practices if I can.

TIA
Simon

[android-developers] How to get a reference to the stock launcher activity object?

[Daniel]

 

I want to read out the shortcuts' and widgets' position and name on the 
screens of the launcher. Since every launcher is different, I will focus on 
the stock launcher of Android for the moment. I have not found an API to do 
this, so I am trying my luck with Java's Reflection API. So far I have been 
able to get the class and read out the type of the variable holding the 
items on the desktop called mDesktopItems: 
http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android-apps/2.2.2_r1/com/android/launcher2/Launcher.java#201But
 to read out the variable's content, I need a reference to the launcher 
activity object. It's obvious that this object does not have to exist, but 
I can probably check regularly and once it does, I would fetch the data.

So how do I get a reference to the launcher activity object? Or could you 
think of a better way of fetching the required data?

[android-developers] Re: Android 2.2 VideoView Scaling

[Deniz Tuna]

I have also the same exact problem as Richard does. Anyone knows how to 
make those videos fit into the region that is given by me? Thanks in 
advance.

3 Mayıs 2012 Perşembe 13:13:25 UTC+3 tarihinde Richard Davison yazdı:

 Hi,

 I'm trying to create an app that plays a rtsp stream. I'm having no 
 problem doing that, the problem I'm having is that the VideoView simply 
 cuts out a box of the dimensions I set it to, rather than scaling the video 
 to fit the dimensions. I have tried creating my own custom VideoView and 
 overriding the onMeasure method, but this does not scale the video to fit 
 either, it simply cuts out a box of the set dimensions. Does anyone have 
 any idea how to fix this, or if this is an already known bug with 2.2?

 Thanks,
 Rick

[android-developers] Android Picasa Image Uploader

[Lex Luthor]

Hi, I am looking samples to upload a selected picture from my device
to Picasa Album. Is there any way?
I tried this snippet:
   Intent temp = new Intent(Intent.ACTION_SEND);
   temp.setType(image/png);
   temp.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
   temp.putExtra(Intent.EXTRA_STREAM, fileUri);
   temp.setComponent(new ComponentName(
   com.google.android.apps.uploader,
 
com.google.android.apps.uploader.clients.picasa.PicasaSettingsActivity));
   try {
   startActivity(temp);
   } catch (android.content.ActivityNotFoundException ex)
{
   Log.d(TAG, Errore upload Picasa);
   }
which works, but in this way I can't insert a comment (only a legendy
that will be displayed above the pic), while to insert a comment I
have to do it manually from browser (after upload).
I'd like to know if there's a way to get the image URL after uploading
it.

[android-developers] How to get stream video(m3u8 format) resolution from url link, android2.3.3?

[Baiqi WU]

I have tried many ways to retrieve the video meta data from url like
(http://xxx.xxx.xxx.xxx/streams//playlist.m3u8), the project is
useing android 2.3.3 SDK.

1. As I know the MediaMetadataRetriver can solve it with capture_mode
but it needs the android vesion level after 14, but android 2.3.3 is
level 10. (it doesnt work in project).

 MediaMetadataRetriever retr = new MediaMetadataRetriever();
 retr.setDataSource(mContext ,
video.getUriWithDrmCheck());
 retr.setMode(MediaMetadataRetriever.MODE_CAPTURE_FRAME_ONLY);
 Bitmap bm = retr.captureFrame();
 int wVideo = bm.getWidth();
 int hVideo = bm.getHeight();


2. I have been used vetamio to retrieve the video resolution, but the
system crashed.
io.vov.vitamio.MediaPlayer m= new io.vov.vitamio.MediaPlayer(this);
m.prepareAsyc();
m.setDataSource(url);
m.getVideoAspectRatio();
m.release();

3. The default android.media.mediaplayer in android could not retrieve
the url video information.
The video height I got from it is 0.

4.  I tried thumbnail method to retrieve the video information, but
the Thumbnail method seems can only phase the localPath, not the url
link path.
Bitmap bMap = ThumbnailUtils.createVideoThumbnail(url,
MediaStore.Video.Thumbnails.MICRO_KIND);



So does any one know how to retrieve a stream video (m3u8 format)
resolution from url link in android?? thank you very much.

[android-developers] Android Code Architecture

[Claudius Ibn]

I started learning Java and Android yesterday, so I`m totally a newbie...

I`m developing an app, it will have some basic functions: authentication, 
post comments, location...

My doubt is how to organize the code, I`m asking now because my code is 
small, but in a few months... I want to make everything very organized! 
I`ve done a basic authentication... I`ve only one activity, here it 
is: http://pastebin.com/Zt9fiq7r and here is my Authentication 
class: http://pastebin.com/kBS7pDJM

I added this part to be sure that session is working:

 if (user) {
 Toast.makeText(this, Usuário logado., Toast.LENGTH_LONG).show();
 sessionEditor.remove(user).commit();
 }


How can I change the layout when the app open if there`s a logged user? 
When should I create new Activities? What`s the best way to change the 
layout?

Thanks in advance! :)

[android-developers] changing process priority

[kani]

Hi all,

I am trying to change the priority of another process through the
method, setThreadPriority (int tid, int priority) how ever I am
getting the security exception saying I don't have permission to
modify the given thread. Is there any permission that I must add to
the android manifest?

will it be possible to issue setThreadPriority (int tid, int priority)
on another process if my app runs as root? currently it has
app_someOn. if so how can I make my app run as root?

Thanks,
Regards,
Kani

Hi all,

I've gp the sample code for Browser plugin from the Froyo source

I built the plugin and install it on emulators (GingerBread and
Honeycomb). I test it with opening a local html file with the web
browser and it works/

However, when I install the plugin on my device and I open the same
html file with my browser, nothing happens. The plugin is not loaded.

Do you have any idea ?

[android-developers] Software and Game dedicated keyboards

[isaac tanner-dempsey]

Dedicated keyboard skins are available like this
http://www.solotype.com/images/thumbs/0001168_430.jpeg which showed
shortcut keys cheat sheets directly on the keys. This is called a
dedicated keyboard.
I was thinking I would be great if these dedicated keyboard skins were
available on tablets I haven't seen this type of thing yet.
Even an on-screen keyboard for pc's to use as a cheat sheet could be
helpful there are not many option available to help mesmerising these
- I'm always forgetting the Photoshop shortcut keys. When I'm working
between after effects, and illustrator and autocad it's gets very
confusing each software has different shortcuts. If I could work on
tablet and either preview the shortcut key by having them display
beside the key letters or switch between a visual text keyboard and
a shortcut keyboard I could be more productive, I'm not suggesting
keys in that link I've supplied are good design it's just an example.
I will make a keyboard if someone wants to make this just email me
template...

[android-developers] VOIP call hand off from 3G/4G to wifi and back or vice versa

[Maconsultant]

I am curious if anyone has played around with the VOIP stack in ICS. I
have found that durning a voip call over 3g/4g if you move into an
area with a known associated wifi network the phone will connect to
this wifi network and drop the 3g connection and along with it the
voip call. this does the exact same thing from wifi to 3g/4g as well.
now my question is how can one get it to hand off the active call when
switching between cellular and wifi networks.? In theory i know how
this should work.. has google just not implemented this into the VOIP
stack of ICS..? this would be a killer feature and take the android OS
over the top.. Thanks for your time..

[android-developers] noob developer, application keeps restarting

[jon dattilo]

Hi everyone,

I'm working on developing my first real application beyond the basic
tutorials. It is a fairly simple flashcard program for me to use in
school and I have it up and running smoothly. It utilizes a set of
variables to keep track of how many and which cards I have seen,
nothing too fancy. However, sometimes when I switch to another
application and come back to my program, it restarts everything, while
in other instances it will pick up where the program left off. There
doesn't seem to be any pattern to when the program resets, and I don't
have any task killer software installed that would end the program
without my knowledge.

I am inquiring how I tell the program to simply continue running in
the background, and then if there is a function I can insert to quit
the program so I can assign that to a button? I posted the start up
code below, and would be happy to post more if someone could direct me
to what would be relevant. As you can see I have it programed to go to
the app's home screen when the app loads for the first time, which
works if the app has quit and is restarting, but in most circumstances
it resumes the flashcard portion, almost as if you had loaded the
program and pressed the resume button from the home screen (which is
what I want to happen all the time). I would be fine with loading the
home screen every time someone switched out of the application, as
long as the variables didn't reset when that happens. Any advice would
be much appreciated.

@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
goHome();
}

public void goHome(){ //defines the home screen
setContentView(R.layout.home);


final Button instructionButton = (Button)
findViewById(R.id.instructionButton);
instructionButton.setOnClickListener(this);

[android-developers] Publishing free and paid versions of the same app

[Kaptkaos]

Hi all,
I have a free version of my app posted on Google Play. I have had some 
demand to provide a paid version also. When I tried ti upload the APK for 
the paid version, Google Play complained because it used the same package 
name as the free version.

   What is the recommended way to handle this? Obviously the free and paid 
version are very similar in their code base. I don't want to maintain 2 
different projects if I can help it. Any recommendations for solving this 
problem? Is there a standard way to organize projects to achieve this goal? 

   Many thanks in advance!

[android-developers] Re: Licensing response with release APK

[Oded]

My understanding is that if you are logged in with your developer
account on your device then it will always show whatever the test
license status is from the server. If not and it's a draft (not yet
published) app, then it will always return LICENSED.

See 
http://developer.android.com/guide/market/licensing/licensing-reference.html#server-response-codes
under LICENSED

[android-developers] Bitmap rotation performance

[Mauro]

Hi you all,
the question is simple: how to accomplish the bitmap rotation for big
size bitmap without blocking the user for a lot of seconds? For
example in the default android gallery you can rotate an image in a
very fast manner.

I thought to apply the matrix rotation on the ImageView (which can be
done in a few time) and compute the same matrix rotation for the
bitmap on an AsyncTask, but if the app is stopped before the task
termination i get an inconsistent state.
Any help will be appreciated.

Thanks,
Mauro.

[Leif Jakob]

Hi,

I've found an ugly solution working for android 2.3 (implementing an 
android.net.http.RequestQueue and gluing it into the framework with 
reflection) but it doesn't work on ICS anymore... If your ICS is compiled 
with CHROME_NETWORK_STACK you are out of look.

The idea with a proxy is ok, but if you want to read post-headers for SSL 
sites you get in even more trouble.

 I'd like to be able to distinguish between Mobile non-Access-Point,

 When a 2.2 phone is configured as a Mobile Access Point, WifiManager 
 says that the wifi is disconnected. ConnectionManager says pretty much 
 the same: that the connection is mobile rather than wifi. The only 
 distinction I seem to be able to make is that the IP address when 
 acting as an Access Point is 192.168.*, rather than 10.*.*.*. 
 That doesn't seem like an entirely safe way to do things. 

 The application: I really don't want to send SSDP broadcast packets 
 onto a 3G network. I can't imagine it would actually work. But if it 
 did, the results would be truly catastrophic. So I'd just plain rather 
 not. 

 I'd like a safe way to distinguish the two case: Mobile/no- 
 AccessPoint, and Mobile/with access point. 

 Anyone?

So we commented the code which was responsible for firmware download.
Now phLibNfc_Mgt_Initialize() function in same file retuned nfcstatus
as [NFCSTATUS_PENDING].


We dont know were the context is being set to NULL.

The device /dev/pn544 is opened and appropriate log msg is being
displayed.

But phHciNfc_Initialise() function returns NFCSTATUS_PENDING in
phHal4Nfc.c.

Please do reply if anything can be done.

Re: [android-developers] Publishing free and paid versions of the same app

Your pro version must have a different package name from the free one. This

Re: [android-developers] noob developer, application keeps restarting

[Raghav Sood]

When it is in the background, Android kills your application when it needs
more resources. One way to keep your data would be to write it to
SharedPreferences in onPause(), and read it from the same in onResume().

 Hi everyone,

 I'm working on developing my first real application beyond the basic
 tutorials. It is a fairly simple flashcard program for me to use in
 school and I have it up and running smoothly. It utilizes a set of
 variables to keep track of how many and which cards I have seen,
 nothing too fancy. However, sometimes when I switch to another
 application and come back to my program, it restarts everything, while
 in other instances it will pick up where the program left off. There
 doesn't seem to be any pattern to when the program resets, and I don't
 have any task killer software installed that would end the program
 without my knowledge.

 I am inquiring how I tell the program to simply continue running in
 the background, and then if there is a function I can insert to quit
 the program so I can assign that to a button? I posted the start up
 code below, and would be happy to post more if someone could direct me
 to what would be relevant. As you can see I have it programed to go to
 the app's home screen when the app loads for the first time, which

Move all of the common code to a library project. You will need two

I did multi tasking using activities, Asyctask, hidden layouts in a 
Relative lout,etc.

But Fragments is the best solution, I believe.Not sure about compatible 
jars of fragments that works in lower versions, but heard that it works 
equally good.

I think every knows that some  UI features still very in iPhone, we can 
easily overlay a screen on another without coding effort or less coding.
But Android certainly gives the rich ness and User friendly experience with 
fragments that are better than iPhone in some scenarios.

 If you write an app that allows the user to change an Activity's data and 
 state (that is not backed by input fields such as EditText, etc), you'd 
 need to persist this data when the activity (and application) is restarted. 
 However, you don't need to implement you own database/persistence/storage 
 for this. Just implement the callback method onSaveInstanceState correctly 
 (save the data/state into the provided bundle) and read the data from this 
 bundle in the onCreate. Easy peasy. Or use a (hidden) Fragment. Even more 
 easier peasier.

 And yes, I have programmed an Android app

[android-developers] Re: Listview with multiple layout

[Mek Rama]

Layout:
Two layout xml  files:  1)one layout for listview 2)another layout for list 
items.  use two textview widget  and arrange it one below other.
Layout:  1)linear layout 2)relative layout or use combination of relative 
and linear

application code:

use i)SimpleCursorAdapter ii)custom adapter that fits your requirement

Referece : 
http://developer.android.com/reference/android/app/ListActivity.html
Use  list adapter similar to examles in  listing 4 and 14

[android-developers] Re: Accessing Front and Back Camera at the same time

[Mohit Ramani]

From what i know is that it is not possible. You are right the hardware is 
different for both but the software that accesses the camera is same and it 
can only use one camera at a time.

 to access the front camera.

 But what I don't understand is why is there such a limitation?

 Isn't front and back cameras are two different pieces of hardware?

 Or can this be done and am I wrong?

[android-developers] call an Activity by intend and callbyvalue

[superpsycho]

Hi,
i´ll want to call the NextActivity, give an integer to its creation
and identify whats to create by the given int.
My existing code is like:

1. Intent dosth = new Intent(ThisActivity.this, NextActivity.class);
2. startActivity(dosth);

what i simply want to have is:

1. Intent dosth = new Intent(ThisActivity.this,
NextActivity(integervalue).class);
2. startActivity(dosth);

The called activity looks like this at the moment:

1.public class NextActivity extends ListActivity{
2.  private final int idoflist;
3.
4.  public NextActivity(Integer idoflist) {
5.  this.idoflist = idoflist;
6.  }
7.  @Override
8.  public void onCreate(Bundle savedInstanceState) {
9.  super.onCreate(savedInstanceState);
10. final String[] text =
getResources().getStringArray(R.array.text_array);
11. setListAdapter(new ImagedArrayAdapter(this, beverages,
idoflist));
12.
13. ListView listView = getListView();
14. listView.setTextFilterEnabled(true);
15.
16. listView.setOnItemClickListener(new OnItemClickListener() {
17. public void onItemClick(AdapterView? parent, View 
view,
int position, long id) {
18. System.out.println(id);
19. }
20. });
21.
22. }
23.}

the actual problem is that the
1. Intent dosth = new Intent(ThisActivity.this,
NextActivity(integervalue).class);
doesn´t work like expectet cause i don´t know what i have to do :D

[android-developers] Content Providers

[Mohit Ramani]

Hi All,

I am developing an application which will have to catch notifications for 
Incoming SMS, Outgoing SMS, Missed Calls, Incoming  Outgoing E-mails. Now 
I have found a way to get all these notifications except for the e-mail 
which seems impossible at the moment, but my question is will these be 
supported in future OS as well. What i saw was that managedQuery function 
has been deprecated in 4.0.3, so now before writing this app I need to be 
sure whether these features will remain as is and the content that content 
providers provide will be the same across all android phones. Since it is a 
sponsored a app I need to convince the investors that the app will work.

Any thoughts on this will be greatly appreciated.

Thanks,

Re: [android-developers] How to check which button is clicked

[ravi saini]

hii
 just implement your class activity from onclickListener and implement its 
method onclick and in that method you can use switch to get which button is 
pressed like
switch (v.getId()) {
  case R.id.im1:
  {
  button1.setImageResource(R.drawable.p1o);
  break;
  }
}

 I hope to get user's country and city without using GPS. Basically, I know
 how to get user's country. I searched some post from the web. It can use
 LocationManager through NETWORK_PROVIDER to have the Latitude  Longitude.
 From Latitude  Longitude, use GeoEncoder to find the city. 

 The follow is my LocationManager part:

 ** **
 1.public void onCreate(Bundle savedInstanceState) {
 2.** **
 3.super.onCreate(savedInstanceState);
 4.** **
 5.setContentView(R.layout.main);
 6.** **

 10. ** **

 12. ** **
 13. ** **
 14. ** **
 15. public void onLocationChanged(Location location) {
 16. ** **
 17.TextView tv01 = (TextView)findViewById(R.id.TextView01);
 18. ** **
 19.TextView tv02 = (TextView)findViewById(R.id.TextView02);

 21.tv01.setText(Latitude：  +
 String.valueOf(location.getLatitude()));
 22. ** **
 23.tv02.setText(Longitude： +
 String.valueOf(location.getLongitude()));
 24. ** **
 25.}

 

 Also I added the android.permission.ACCESS_FINE_LOCATION in
 AndroidManifest.

 After testing, it is no result. 

 Can anyone tell me how to fix it?

 Thanks a lot!

[android-developers] Softkeyboard

[Tony]

I want to program a softkeyboard where you click on a key, and instead
of outputting an alphabet into the textediting area, i want it to
output a different letter or symbol. Sort of like how a japanese
romaji keyboard would work. (eg: when you click on the a, r, i, g, a,
t, o, u keys, it would output あ、り、が、と、う, instantly as you type them.

Anybody have any suggestions on how to set that up?

[android-developers] Re: Help

[Mark]

OOPS..

Here is the code

This all happens from a button pressed on the 2nd layout (items.xml)

private View.OnClickListener onAddItem = new View.OnClickListener() {
public void onClick(View v) {

setContentView(R.layout.additem);

//final AlertDialog dialog = null;


EditText txtItem = (EditText) 
findViewById(R.id.txtgroceryItem);
InputMethodManager inputMgr =
(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
inputMgr.showSoftInput(txtItem,  0);

Button btnDone = (Button) findViewById(R.id.btnDone);
btnDone.setOnClickListener(onDone);

Button btnAddItem = (Button) findViewById(R.id.btnAddGItem);
btnAddItem.setOnClickListener(onAddTheItem);


}
};

[android-developers] Why none of the Motorola add-ons in the SDK cannot be launched in emulator

[technicware]

Hi,

I have the latest Android SDK r19 with several Motorola device add-ons: 
Atrix2, xt882, etc. None of them can be successfully run in the emulator. 
Logcat reports all kinds of error, like file not found, cannot cache xyz, 
no space left on device, etc.

I also have a LG Real3D add-on, and it runs in the emulator with no 
problem. I just create the AVD with default settings and it runs.

Any idea why the Motorola add-ones, doesn't how I tweak the AVD settings, 
will not run in SDK r19 (or r17) emulator?

Thanks
