App open from PushNotification click without payload about gcmpush HOT 4 OPEN

Did you ever find the answers to these questions? I have the same questions.

from gcmpush.

If you specify a callback function when registering for push notifications, this method will be called. The single parameter it takes contains all payload data received from the notification. See the example for details.

@morinel thanks for the response. I have tried the callback, but I'm confused about the actual flow/what it's supposed to do. In my app, the callback gets called right when the push notification arrives. But I want it to be called/something to be called when the actual notification is tapped from the notification list in the pull-down Android menu.

The actual problem I'm having is this - right now I'm relying on gcm.getLastData() on the resume event to try to make something happen when my app is opened/brought to the foreground via a notification tap. But I can't figure out how to differentiate that tap from just opening the app normally, where in that case gcm.getLastData should not be used since it wouldn't make sense to act on the notification contents.

Any help is greatly appreciated. I've been trying for a while to get a flow of notification tap opens content in my app, but I haven't had much luck (it works, but there's weirdness like when you receive a notification but then open the app through the icon instead of the notif, etc.).

After gcm.getLastDate() returned any data you'd like to use in your app, use gcm.clearLastData() to remove it so it won't return any data the next time the app is resumed.
