Not only is the special address the wrong computer, it's unique to emulators and not available on real devices. If using a network socket, loopback is the answer. However, unless you absolutely have to emulate IP networking, it may be preferable to use a unix-domain socket rather than a network one. This will remove the requirement that any apk using it carry internet permission, while keeping many of the semantics comparable. While unix domain sockets aren't the first choice for IPC within android (that would be Binder) they definitely are used within android itself, for example the connection between the adb daemon and a debuggable app process which makes java debugging possible is done via a unix socket. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Performance of different IPC methods
Hi all, In my app the process number 1 generates around 1KB of data every couple of seconds and passes this to process number 2. To my understanding there are three ways to pass data between processes: publishing IPC interface using Binder, using Messeger or using Broadcasts. I would like to get some feedback what would be the best way to pass the data between the processes? Any ideas how android handles these different scenarios? Also would it be more effective to cache the data in process 1 for a while and then send the data in longer intervals and bigger chunks to process 2? Any insight to this is really valuable. I know that this all could be done in one process also, but because of the use case and some external requirements unfortunately that is not really option in my case... -- You received this message because you are subscribed to the Google Groups Android Developers group.

Hi Marcin, Thanks for the reply. :) Yes my idea is to redirect the user to the system settings.

Not really what you expect as answer, but why not just tell user he will be redirected to system settings panel and when he's done BACK would let to return to your activity? While embedding is quite tempting (from your standpoint), launching system settings is common and standard way to that you want to accomplish. Other approaches will most likely be close to luring in hacks and while I am personally not against using hacks, I do that only if there's no better way to do the task (or no other way than hacks).

[android-developers] How does PackageManager detect what architecture APK targets?
Hello everyone, I'm currently trying to specifically target ARMv7 custom hardware and I'm facing issues when trying to install the APK. When I try doing adb install app.apk Logcat informs me that : W/PackageManager( 1062): Native ABI mismatch from package file And does not install the APK. With searching I was able to trace down that the problem might have something to do with the architectures not matching on the APK and the platform. Is this it? How does the PackageManager find out the architecture from the APK file? I'm guessing it's not trying to execute the binary or anything, it just checks the files meta data? If so, is there a place in the APK where this information is located? Or am I completely hitting blank here and I should look somewhere else? I appreciate all comments and tips.

[android-developers] Re: about library projects
Second one might be a bit more involved, but hopefully there is an easy fix. I have my projects into a subversion repository, but the app project builder (Android pre-compiler) seems to copy all the source from the library project, including the .svn folders, to the app/bin project. As a result of this, I get loads of files checked into the commit dialog, and I have uncheck all and then hunt down the files I actually changed. Is there any way to configure it to ignore .svn files when copying source? I realise that it has to merge source from both projects to create the final apk, but .svn files are surely not needed. At least this type of thing worked for me. 1. Delete the bin directory 2. Commit the delete changes to svn When you build your project the bin directory is recreated and it should now have the blue question mark (as telling not is svn) above the folder icon. Now you should be able to add the bin directory to svn:ignore. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] AlarmManager problems in Milestone
Hi All,
I'm having some strange behavior of wakeup alarms scheduled by
AlarmManager in Motorola Milestone (Droid in US). The thing is that
they don't wake the device as they should. The same piece of code
works fine in Samsung Galaxy and the alarms are fired as they should
fire. In Milesstone when the device is in sleep no alarms are fired
but all the alarms are fired at once when the device wakes up. I also
found out that Milestone doesn't have the /proc/wakelocks file to
check the wake lock info but I'm not sure if that has something to do
with the problem. For this scenario there is no reason to acquire a
wakelock because the AlarmManager acquires it automatically for
lifetime of the OnAlarmReceive. I found some other threads about the
same problem in Droid/Milestone, but does anybody have an idea what is
the problem and is there anyway to solve it.
This is the code that I'm using to test this.
/**
* Broadcast receiver for the device boot
*
*/
public class OnBootReceive extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
Intent i = new Intent(context, OnAlarmReceive.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);
AlarmManager m =
(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
m.setRepeating(AlarmManager.RTC_WAKEUP,
System.currentTimeMillis()
+1, 5*60*1000, pi);
}
}
/**
* The alarm receiver

public class OnAlarmReceive extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Log.d(AlarmTester, Alarm fired + new Date());
File log=new File(Environment.getExternalStorageDirectory(),

try {
BufferedWriter out=new BufferedWriter(new
FileWriter(log.getAbsolutePath(), log.exists()));

[android-developers] HashMap, ArrayList and fastest way to iterate Collections on Android (+other ways to make it run like a wild horse)
Simple question, what is the fastest way to iterate through collections on Android? I generally use collection.iterator(); and the iterator.next() to iterate through the whole collection. Is it any faster to drop that and iterate with old (and I use the term old loosely...) : for( int i=0; icollection.size(); i++) ? I was thinking of getting the collection.size() into a separate variable so I wouldn't be asking the collection it's size all the time so basically the for loop would turn into something like this: int size = collection.size(); for( int i=0; isize; i++ ) collection.get(i); Any better? Speed wise, I mean. I'm in a point where I need to get every possible inch of speed for my application. Or maybe allocate everything into Lists in the start, and once I know the correct amount of data, I turn all that into arrays and drop the Lists so I can have array[index] (Log(1) access, right? OH wait.. how did this go again _ ) access instead of having the slow method calls in between like .get(); when accessing the data in the collection. And what about getters setters for Classes? Like let's have a Vector2D class that contains obvious integer x and integer y values. What is the fastest way to access them inside the class? Have them as public and just straight Vector2D.x = someValue; or through getters and setters? I've had much debate with my tutor about this (working on my final year project) but not to get too much into details of it... Also all links for further Android application optimisation are more than welcome and greatly appreciated (I read the googles docs on this already). Plus if you have found some really good tricks / quirks on Android to punish the device even more so it runs faster, do share, do share. Heh. Please be gentle on me, I'm such a beginner in all things Android that I feel absolutely dumb as a boot for asking these kind of things. I come from strong C++ / Java background but getting the extra inch of speed for everything on Android is so different than optimizing code for PC side and not that you even have to do it on PC side that often.

[android-developers] Trying to get rid of my last few Long calculations in my game and completely turn it into FP format. System.currentTimeMillis() giving me a headache.
Like the topic of the thread says. In my game I would like to turn all the calculations into FP format. I can eliminate pretty much everything else but I still need to do the the following calculation in long format. Code: long t = this.lastUpdateTime - System.currentTimeMillis(); The value I get from this is the time passed since last frame, which is like.. two digit millisecond value, which naturally is more than good for FP stuff. After that calculation I turn the resulting value into FP integer and use it with the rest of my calculations but I'd like to get rid of that long calculation too. Any ideas how to go around this to do it in FP format? I mean, I'm pretty sure I cannot just go and do a normal conversion to FP format in this style: Code: int fpT = t * (116); because there is always the change that it'll overflow and as the numbers that System.currentTimeMillis() give out are BIG. So any advice how to keep the same accuracy of the timer but get rid of the long calculation and have it replaced with nice and fast FP calculation. Any advices on how to trim down the System.currentTimeMillis() or what ever to get around this are greatly appreciated.

/FrameLayout
Where MyCustomView is the view that I want to display when a marker is
pressed. Now in may Overlay subclass in the onTap method I do
something like
public boolean onTap(GeoPoint point, MapView map) {
Point pxPoint = map.getProjection().toPixels(point, null);
mListener.onItemClick(pxPoint);
}
here mListener is an instance of my MapActivity subclass where in the
onItemClick method I draw my custom view...
public void onItemClicked(Point point) {
MyCustomView view = (MyCustomView)findViewById(R.id.bubble);
view.layout(point.x, point.y, view.getWidht(), view.getHeight());
view.setVisibility(View.VISIBLE);
view.invalidate();
}
That's the basic idea. You might have to force the layout before
drawing or set some limits to the view width and height, because
getWidth() and getHeight() return 0 before the first layout. But I
think you should get the basic idea how to do this...

[android-developers] Re: OpenGL ES works fine on Emulator but on HTC Hero 1.5 it does not render vertices
Ah sorry for long response time. Anyway, I went back to the problem
and started using GLSurfaceView instead and it works with the current
setup.
With the GLSurfaceView, where am I supposed to implement
onTouchListener? Since if I make the starting activity to implement
the onTouchListener, it never gets called on touch evens.
Any tips what/where it should be implemented?
Cheerio for all the tips.

your problem is there? Consider trying GLSurfaceView and let me know

that it's correctly initializing a GL context and surface on the
device.

[android-developers] Re: Memory leak or feature
Thanks for everybody for helping me with this. I checked the memory also with a memory profiler and I suspect that it is SearchManager that is keeping a reference to the Activity. And it seems that SearchManager is created for default for all the apps even though it is never directly invoked. Anyway, I think I will also file a bug report, because there is something strange happening whether it is in the dev tools or in the platform. But my sample app is so simple that I'm positive it is not leaking anything. As it doesn't in 1.1 OS. The size of your process doesn't make it more likely to be killed. Okey, this I didn't know. I though that when the OS decides to kill processes in order to reclaim memory it does it so that the larger processes are killed first. My mistake, should read the docs more carefully. (4) My meminfo results were slightly different than what Mika reported at the beginning of this thread. When the Activity is the foreground my process had 14 views, 4 AppContexts, 2 ViewRoots, and 2 Activities. After the Activity was destroyed it had 7 views, 3 AppContexts, 1 ViewRoots, and 1 Activities. So SOMETHING happened but I don't know how to interpret theses numbers - why would there be so many views, etc. for a simple 1 TextView application? I have these same results if I start the activity close it from back button and then start it again. Anyway, thanks for help everybody. Now it's time to go to fight MapActivity memory problems =) -Mika On Oct 22, 3:31 am, jotobjects jotobje...@gmail.com wrote: That may be. In this test the memory usage by Dalvik reported by meminfo never decreased even though the JVM Runtime memory usage did fall when the Activity was destroyed. The main point is that there is not a close correspondence between memory usage reported by Linux process stats and JVM free memory. So meminfo is not the best way to detect application memory leaks.

[android-developers] Re: Memory leak or feature
Thanks for the replies. I checked that finish() is called for the activity when the user presses the back button. why do you expect the system to close the Activity and free the memory Well basically because if I want to do some background processing (playing music, tracking location etc.) while the user is doing other things I would want my process to use memory as little as possible so that the system wouldn't kill it. But if my UI i.e. Activities stay in the memory even when they are not used it makes the background process more likely to be killed. I also tried using some memory extensive apps (Maps, Browser, Camera) but the system still didn't free the activities of my app. if you are somehow measuring things incorrectly. That might be the case. So here is a brief explanation. 1. The sample app that I'm running can be found from: http://users.tkk.fi/~mristima/android/service_test.tar 2. I start the app 3. To check the memory consumption I run: adb shell dumpsys meminfo com.android.service_test. 4. I press the back button 5. From DDMS I force GC for system_process and my app process 6. Finally I run adb shell dumpsys meminfo com.android.service_test again. Is there something wrong or strange here?? Also what is interesting, is that using android 1.1 (AVD) as a target, all the activities are freed from memory but in 1.5 they are not. I'm really baffled about this, so it would be great to have some kind of explanation for this, or to understand what I'm doing wrong. -Mika On Oct 21, 1:10 am, Dianne Hackborn hack...@android.com wrote: I am pretty sure the standard music app doesn't leak, so I wonder if you are somehow measuring things incorrectly.

[android-developers] Basic game structuring with two threads?
Hello people.
I've gone through several Android examples, tutorials and generally
just played around with the system. Now I'm in a need of help
concerning a making of a game for Android, more specifically
structuring the design. I'm going to use OpenGL to render everything.
Generally when I have programmed games on the PC side I've gone about
it roughly in this manner:
game_loop( running )
{
updateInput();
updateGameLogic(); // enemies, objects, etc. stuff
renderEverything();
}
That's it in a nutshell, of course I've generally added interpolation
of rendering. Basically having an if statement saying that if over X
amount of time has passed do update and render as fast as possible
with the interpolation. But how should I go about this on Android?
Since doesn't OpenGL ES require a separate thread for itself and I
really don't want to do my update stuff in onDraw() of the OpenGL
thread. So any links, help or just generic tips where to look on how
to build the structuring properly? Aiming to get it to look something
like this:
game_loop( running )
{
readInput();
if( has 20ms passed )
{
updateGameLogic(); // enemies, objects, etc. stuff
}
float t = calculate interpolation point based on time;
renderEverything( t ); // this supposedly then ... calls the ...
rendering thread? Which we cannot really call like a function..
ugh..
}
Or is it done completely different on Android? How could I achieve the
same effect/flow of events. But yeah kind of need a help to point me
in the right direction on how to structure things on Android and from
there I can take care of the rest.
Thank you.

[android-developers] Re: Memory leak or feature
Hi Dianne, This is what I assumed also. Do you have any ideas where the leak could be in the sample app that I posted? I also checked the music player app with meminfo and it behaves similarly leaving activities in memory even after the ui is closed and system_process and com.android.music processes are GCed from DDMS. I also tested with 1.1 SDK and Emulator and there everything works as presumed and no activities stay in memory after they are closed. -Mika On Oct 15, 7:56 pm, Dianne Hackborn hack...@android.com wrote: If you press back and let the system finish the activity, all references to it will be gone, so though your process is there after it GCs the resources (views etc) associated with the activity should be gone. If you still see them after you know the process has GCed, then you have a leak in your app. On Thu, Oct 15, 2009 at 7:57 AM, String sterling.ud...@googlemail.comwrote: On Oct 15, 3:08 pm, Mika mika.ristim...@tkk.fi wrote: So the problem is quite simple.

[android-developers] Memory leak or feature
Hi,
So the problem is quite simple. I start a Service from an Activity,
the user presses back, the Activity goes away and the Service stays
running in the background. However the activity (and it's views) still
stay in memory. Any ideas why is that?? I tested this with cupcake and
G1. To reproduce I've made a simple program.
The activity:
package com.android.service_test;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class StartService extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
startService(new Intent(getApplication(),
RunningService.class));
}
}
The service:
package com.android.service_test;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
public class RunningService extends Service {
@Override
public void onCreate() {
super.onCreate();
}
@Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
new Thread(new Runnable() {
public void run() {
while(true) {
System.err.println(running);
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch
block
e.printStackTrace();
}
}
}
}).start();
}
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
}
Manifest:
?xml version=1.0 encoding=utf-8?
manifest xmlns:android=http://schemas.android.com/apk/res/android;
package=com.android.service_test
android:versionCode=1
android:versionName=1.0
application android:icon=@drawable/icon android:label=@string/
app_name
activity android:name=.StartService
android:label=@string/app_name
intent-filter
action android:name=android.intent.action.MAIN /
category
android:name=android.intent.category.LAUNCHER /
/intent-filter
/activity
service android:name=.RunningService /
/application
uses-sdk android:minSdkVersion=3 /
/manifest
With this sample the activity on foreground, meminfo gives
** MEMINFO in pid 633 [com.android.service_test] **
native dalvikothertotal
size: 2368 2819 N/A 5187

And after the activity has been destroyed meminfo gives:

And I remembered to force the garbage collector to system_process and

Hi, but if I change the system time in //do something , how to caculator the spentTime? From the API docs: This method (System.currentTimeMillis()) shouldn't be used for measuring timeouts or other elapsed time measurements, as changing the system time can affect the results.

Yeah sure.. but I understood that the question was about notifications
when the sms is not sent form within your own app. For example when
the user uses the default messaging app to send an sms.

[android-developers] Re: MapView Overlays
What you could try is to use just one instance of your Overlay subclass that includes all the 60 icons that you want to show on the map. -Mika On Oct 1, 4:08 pm, Ne0 liamjamesalf...@googlemail.com wrote: Not had any response, but my solution is to add a bit of intelligence to my activity to only add the overlays that would be displayed on the map currently visible by the map view. I have no idea about how the mapView goes about doing this, but it appears to be really slow at doing so. So i am going to let my activity take the strain and see if it makes it any better. Any thoughts on this issue are still greatly received.

When i decreased the overlay icon size, it did improve things, though it is still to slow to be usable. Has anyone experienced anything similar and have a workaround? There may be a better way of doing it other then extending the Hello MapView example. Any thoughts welcomed.

[android-developers] Re: java.lang.OutOfMemoryError after orientation changed
From the stack trace it seems that your trying to allocate 160 MB of memory. And for one app the max heap size in Android is 16 Mb (if i remember correctly). That's why the outofmemoryerror.

PID: 11513 SIG: 9 Any ideas is this a bug in the platform, or is it possible that the application I'm developing (or some other app in the device) is doing something that makes the whole system crash. I'm using 1.1 SDK but the device has 1.5. Could those compatibility issues be the reason for the crash?? -Mika --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: getView from CustomizedAdapter called several times
Hi,
I'm having the same problem. Did you find any solutions??

Hi Everyone,
I am implementing my ownadapterthat inherits from BaseAdapter (this
is something very classic).
Then when I start the activity that owns the listView binded to thisadapterI
can see that the getView() method is called moretimesthan
what the number of view actually available in the list.
For instance, I do have 2 rows in my list and when I first set
theadaptergetView is called 6times. Then If I make a call to
notifyDataSetChanged(), getView is called 4times.
I understand that when you scroll up and down getView must be called
to generate or re use a view but I don't scroll up or down, I am
really wondering why getView is called so many time.
Thanks a lot in advance for your responses.
Jabu
My code just in case even though it is a pretty basic piece of code:
public View getView(int position, View convertView, ViewGroup
parent)
{
ViewHolder holder;
if (convertView == null)
{
convertView = mInflater.inflate(R.layout.row_action,
null);
// Creates a view holder
holder = new ViewHolder();
...
convertView.setTag(holder);
}
else
{
holder = (ViewHolder)convertView.getTag();
}
holder.params.set
return convertView;
}

[android-developers] Re: Is possible get notified when the user send an SMS or make a call
By browsing this mailing list and android source code. You can also use PackageManager to get the available content providers. If there's some other ways I'd like to know also. -Mika On Jun 10, 7:31 pm, Monkiki monk...@gmail.com wrote: Great, I will try it. Where can I find more info about these context:// uris?

[android-developers] GMail content provider
Hi, My question is quite simple, how to read the data from the GMail content provider. I can get the notify of changes in the GMail database by registering a ContentObserver for content://gmail-ls uri. Then I've been trying to read the following tables content://gmail-ls/messages and content://gmail-ls/unread/^i. But the Cursor that they return is always null. I also tried to register a broadcastReceiver with IntentFilter with Intent.ACTION_PROVIDER_CHANGED because the documentation says that GMail content provider broadcasts that intent, but the onReceive() method in the BroadcastReceiver is never called. Gmail.java can be found e.g. here http://www.google.co.in/codesearch/p?hl=en#uX1GffpyOZk/core/java/android/provider/Gmail.javaq=gmail.java I searched the mailing list and found several similar questions but no answers. So any other ideas?? -Mika --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How to know when map has zoomed?
Hi all, I was wondering is there any way of knowing when the zoom animation in map view has ended?? After each zoom I need to calculate how far my overlays are from each other, but I haven't figured out yet how to know when the map has been zoomed. Is there any way to do that?? -Mika --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: HttpUrlConnection problem
I can't use DefaultHttpClient because I need to get the OutputStream for writing to the remote server. But anyway... I accidently got this working, by calling the method that starts the thread (where all HttpUrlConnection stuff is handled) from an Activity class. Before I had it in a class that implements the onClickListener interface. But I have no idea why it is working now correctly. -Mika On Apr 23, 9:39 pm, Streets Of Boston flyingdutc...@gmail.com wrote: I had a similar issue and i gave up. Instead i used the DefaultHttpClient class together with HttpPut/ HttpGet/HttpResponse classes. This works fine.
