[android-developers] Memory Leak problem (about activity background)
Hi!! Dear All, I have an app that contains many Activity. (ex: i got 10 Activity which be named a1,a2,a3,a10) and all of the Activity(a1,a2,a3a10) have background like this. http://schemas.android.com/apk/res/ android" android:background="@drawable/bg_normal"> and a1 will redirect to a2, a2 to a3, a3 to a4, . then..the problem is happened 【OutofMemoryError: bitmap size exceeds VM budget (Android)】 I think the problem is background.. I know how to unbindDrawable or recycle a bitmap, but how to release the memory after I change activity 【startActivity(aX,aY)】. I have tried to 【view.getBackground().setCallback(null)】 at onPause(). but the heap is still not released... Does anyone know how to solve this problem? or have a better suggestion? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

it's doesn't work on 2.2 device, no matter on nexus one or 2.2
emulator...

this is my code
public class serviceSDcard extends Service {
private static Context contextService = null;
private static AppWidgetManager awmService = null;
public static boolean bIsUnmount= false;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onStart(Intent intent, int startId) {
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(Intent.ACTION_MEDIA_MOUNTED);
intentFilter.addAction(Intent.ACTION_MEDIA_UNMOUNTED);
intentFilter.addDataScheme("file");
intentFilter.addDataAuthority("*", null);
registerReceiver(receiver, intentFilter);
super.onStart(intent, startId);
}
private BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
try {
bIsUnmount = !bIsUnmount;
if
(intent.getAction().equals(Intent.ACTION_MEDIA_UNMOUNTED)){
beauty_large_main.fos.close();
}else{
}
} catch (Exception e) {
Log.d("main", e.toString());
}
}
};
}

[android-developers] I registered a broadcast to detect sd card status, but it only works on the device below 2.1(include 2.1)
I registered a broadcast to detect sd card status, but it only works
on the device below 2.1(include 2.1)
it's doesn't work on nexus one or 2.2 emulator...
android os will kill my process on nexus one and 2.2 emulator, but it
won't do that on device below 2.1(include 2.1)
is there anything wrong?
