The Geoloqi SDK doesn't handle that by default because we don't know what activity you want to open when a notification is tapped.
You can implement this functionality yourself by disabling the default notification handler by calling LQSharedPreferences.disablePushNotificationHandling(context) and writing your own receiver to handle the LQBroadcastReceived.ACTION_PUSH_MESSAGE_RECEIVED intent. You'll have to register the receiver dynamically in your service or activity, or you can add it to your AndroidManifest.xml
