Android 4.x devices receive GCM messages, but Android 2.3 devices do not

Question

My Android app never receives GCM messages on 2.3 devices, but it works on 4.x devices. I can successfully register all devices (2.3 and 4.x). I thought this might have something to do with this issue , but it looks like I have set up the manifest for Android correctly. Can anyone look into my IntentService and BroadcastReceiver and see if they notice any problems? Any help would be greatly appreciated. Please note that onHandeIntent () is never called for Android 2.3 when sending notifications while I have a debugger connected. I checked 4.x devices and they start the debugger in onHandleIntent (). Thanks!

Broadcast Receiver:

 package my.package; import android.app.*; import android.content.*; public class GcmBroadcastReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { NotificationIntentService.runIntentInService(context, intent); setResultCode(Activity.RESULT_OK); } } 

Notification Intent Service

 public class NotificationIntentService extends IntentService { private String TAG = "NotificationIntentService"; public NotificationIntentService() { super(AppConstants.GCM_SENDER_ID); } public NotificationIntentService(String name) { super(name); // TODO Auto-generated constructor stub } private static PowerManager.WakeLock sWakeLock; private static final Object LOCK = NotificationIntentService.class; static void runIntentInService(Context context, Intent intent) { synchronized(LOCK) { if (sWakeLock == null) { PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE); sWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "my_wakelock"); } } sWakeLock.acquire(); intent.setClassName(context, NotificationIntentService.class.getName()); context.startService(intent); } public final void onHandleIntent(Intent intent) { try { String action = intent.getAction(); if (action.equals("com.google.android.c2dm.intent.REGISTRATION")) { //don't care. } else if (action.equals("com.google.android.c2dm.intent.RECEIVE")) { handleMessage(intent); } } finally { synchronized(LOCK) { sWakeLock.release(); } } } private void handleMessage(Intent intent) { Bundle b = intent.getExtras(); String text = b.getString("text"), title = b.getString("title"), largeImageUrl = b.getString("largeImageUrl"); Log.i(TAG, "Message is " + text); NotificationManager nm = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE); Bitmap bit=null; if (largeImageUrl != null && !largeImageUrl.isEmpty()) { try{bit = BitmapFactory.decodeStream((InputStream)new URL(largeImageUrl).getContent()); } catch (Exception e){} } NotificationCompat.Builder nc = new NotificationCompat.Builder(this) .setContentTitle(title) .setContentText(text) .setSmallIcon(R.drawable.ic_launcher) .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)) .setAutoCancel(true) //notification disappears when clicked .setContentIntent(PendingIntent.getActivity(this, 0, new Intent(this, MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT)); //bit = Bitmap.createScaledBitmap(bit, android.R.dimen.notification_large_icon_width, android.R.dimen.notification_large_icon_height, true); if (bit != null) nc.setLargeIcon(bit); nm.notify(0, nc.build()); } } 

Answer 1

The first potential problem I see is this:

The package name in the permission element does not match the name in the uses-permission element. In my application (which is designed for Android 2.2) they are identical.

 <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <uses-permission android:name="my.package.matchtracker.permission.C2D_MESSAGE" /> <permission android:name="my.package.permission.C2D_MESSAGE" android:protectionLevel="signature" /> 

Answer 2

If you use the product flavor with a different applicationId, see my answer to the question GCM messages are not accepted on android 2.3.6 v, but work fine on android 4.X v

Answer 3

GCM requires Google Play services installed on the device, but in version 2.3 it is not installed by default.
