How to handle tap of notification in Android if displayed automatically by GCM

Question

I faced 2 issues in Android with the latest update to GCM. As per GCM, it will automatically display notification in the tray if the payload contains 'notification' attribute. But they have not mentioned how to handle on tap event for that notification. If the payload contains only data attribute, 'onMessageReceived' of GCMListenerService is invoked. But if the payload contains both notification and data attributes, the method is not invoked. Any idea how to resolve? I have to check iOS as well to see how it behaves there.

You need to set a click_action in the notification payload. Then when the user opens/clicks on the notification, an Activity in your app declared with that action will be launched.

e.g set click_action: OPEN_ACTIVITY_1, and add the following intent filter to the desired Activity:

<intent-filter>
  <action android:name="OPEN_ACTIVITY_1" />
  <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

Then you can extract the data from the message in the Activity, by using getIntent() and then looking at the intent extras.
