Receive pushes when app is closed

[lawjeremy]

Is it possible with this library to receive pushes when the app is closed and out of memory?

[morinel]

Sure, use gcm.getLastData() when the app starts or resumes to retrieve the data from the last push notification and act accordingly in your app. See the example for how this could work.

What I'd like to do is pop up a notification while the app is still closed, prompting them to open it. Is this possible?

[morinel]

Well, the notification will be shown in the normal way (either at the top, or as a alertbox you have to click to open the app / dismiss it) If you click it, the app will open / resume and then you should use gcm.getLastData() to do anything specific to process the data in the notification itself.

The problem I'm having is that I don't get anything on my device (in the tray or an alert) from the push until I open the app.

[morinel]

Do you see the notification being received by the app in logcat?

[lawjeremy]

My app is allowed to show notifications. I don't see anything in logcat that looks like a notification, what should I be looking for?

[morinel]

Search for "Push notification received" for log category GCMIntentService.

Digging through logcat helped me find the problem

[ 07-02 20:52:56.441 25483:25502 D/GCMIntentService ]
(IntentService[GCMIntentService--1]) [5,647] Message received but no message so will make this silent

I had my message key in the payload capitalized

"Message": "Hello World"

There's half a day I'll never get back. Thanks for all your help!
