Is there a way to debug the app on receiving push notification using GCM?

Question

Initially my app is closed and when I receive a new message from GCM push service, I am starting a new activity from onMessage() in my class which extends GCMIntentService. I want to use the debugger to check some errors. My question is that is there a way to Debug the app when started from the Push Notification?

To clear a bit more, I have a BroadcastReceiver and a service attached to it. Even is the app is closed, it receives the broadcast and starts an activity based on the message received. It is possible that the app receives the broadcast when it is not open. Now, when the app is open and I get a Push Message then I can debug it. But the problem is when when app is closed and it receives the broadcast, then how to debug it?

Answer 1

@Override
public void onMessageReceived(RemoteMessage remoteMessage)
{
    /*
      the following line will halt the app here
      to give you time to attach the debugger
    */
    android.os.Debug.waitForDebugger();

    /*
      then you can put a breakpoint on any line
      after that, like here:
    */
    Log.d("onMessageReceived", "From: " + remoteMessage.getFrom());

    ...
}

You can put the line android.os.Debug.waitForDebugger(); anywhere in your code where you want to stop execution and attach the debugger. Just remember to remove it when you're done debugging.
