 ### I can't get data notification when app is killed?
 If you send notification with payload only, you can only get the data message when app is in foreground or background. Killed app doesn't receive onMessageReceived
 ### App running in background doesn't get onMessageReceived if app is running in background
-Well these is [an issue opened there](https://github.com/google/gcm/issues/63). You will received data payload if you click on the notification. But if you just open the app, the data is lost.
