I'm stuck for a while on a mysterious problem. So I implemented GCM in my android app, but i receive an INVALID_SENDER error.
The weird thing about this is that i already have a registration id to send notifications to. So my console looks like this:
03-26 09:39:20.233: I/<test>(19761): Already registered: APA91bG6- O3OnZt50EAjYvJ5KETv3qAlPOn2SfOPXez7SLAmaAOkHTN6EMDJb91gFIWkftZkJiub6UoEk4O- WQP7kk2oZGQjZ1VCZZS0WddQtjFaCfYfZfb7SEw3IS1sd4caJcdZE4LA1F0hxzc7Ss1UiYHXX-XXXX
03-26 09:48:23.522: I/<test>(19925): GCMIntentService
03-26 09:39:20.670: I/<test>(19761): on Error INVALID_SENDER
Inside the onCreate:
GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
final String regId = GCMRegistrar.getRegistrationId(this);
if (regId.equals("")) {
Log.i("<test>", "registering");
GCMRegistrar.register(this, "2194354949XX");
} else {
Log.i("<test>", "Already registered: " + regId);
}
broadcastreceiver:
public class GCMBroadcastReceiver extends com.google.android.gcm.GCMBroadcastReceiver{
@Override
protected String getGCMIntentServiceClassName(Context context){
return "be.XXX.XXX.system.GCMIntentService";
}
}
GCMIntentService:
public class GCMIntentService extends GCMBaseIntentService {
@Override
protected void onError(Context arg0, String errorId) {
Log.i("<test>","on Error " + errorId);
}
@Override
protected void onMessage(Context arg0, Intent intent) {
Log.i("<test>","onMessage " + intent.getExtras().toString());
}
@Override
protected void onRegistered(Context arg0, String regId) {
Log.i("<test>","Registration id: " + regId);
}
@Override
protected void onUnregistered(Context arg0, String regId) {
Log.i("<test>","onUnregistered " + regId);
}
public GCMIntentService() {
super("2194354949XX");
Log.i("<test>","GCMIntentService ");
}
}
Manifest:
<permission
android:name="com.XX.XX.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="com.smstiming.hezemans.permission.C2D_MESSAGE" />

<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.VIBRATE" />
<receiver android:name="be.XX.XX.system.GCMBroadcastReceiver" android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="com.smstiming.hezemans" />
</intent-filter>
</receiver>
<service android:name="be.XX.XX.system.GCMIntentService" />
Finally got around this. Was accidentally trying to use the the 'Project ID' instead of the 'Project Number'. Google Developer Console provides both on the Overview page, make sure you are using the correct one.
