ANR Broadcast of Intent { act=com.google.android.c2dm.intent.RECEIVE flg=0x10 cmp=receiver.GcmBroadcastReceiver (has extras) }

I received an ANR log for my BroadcastReceiver, but why? onReceive() is just starting an IntentService, which should probably take some milliseconds, right? And the IntenteService's onHandleIntent() is called in the background?

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // Explicitly specify that GcmIntentService will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(), GcmIntentService.class.getName());
        // Start the service, keeping the device awake while it is launching.
        startWakefulService(context, (intent.setComponent(comp)));
    }
}

// GcmIntentService

@Override
    protected void onHandleIntent(Intent intent) {
        // executing db related stuff

        // Release the wake lock provided by the WakefulBroadcastReceiver.
        WakefulBroadcastReceiver.completeWakefulIntent(intent);
    }

First part of the log:

I've registered my receiver via manifest.xml:

<receiver
    android:name="receiver.GcmBroadcastReceiver"
    android:permission="com.google.android.c2dm.permission.SEND" >
    <intent-filter>
        <action android:name="com.google.android.c2dm.intent.RECEIVE" />

        <category android:name="de.cwalz.receiver" />
    </intent-filter>
</receiver>

When you use:

Context#registerReceiver(BroadcastReceiver, IntentFilter)

  • any application may send broadcasts to that registered receiver

  • you can control who can send broadcasts to it through permissions

  • when you publish a receiver in your application's manifest and specify intent-filters for it, any other application can send broadcasts to it regardless of the filters you specify.

  • to prevent others from sending to it, make it unavailable to them with android:exported="false".

in your case problem is in :

uncaughtException in com.google.android.gms.analytics

(ANR is probably caused by deadlock - main is waiting for Thread:1205)

SOLUTION:

  • filter onReceive() for not intended broadcasts,

  • try catch exception

  • if u cant try Ovverride some methods
