Hello, I am building an app for my high school. It will help keep all the students up to date with announcements as well as a way to contact any member of the staff and other functions as well. I have went ahead and built the base. I followed all the instructions for Android notifications including getting a project number, api key...I did all that. But still when I launch my app on multiple simulators and devices, when the app launches and asks for permission of push notifications, when YES is selected the app crashes. I have spent hours trying to fix this. PLEASE HELP ME!

FYI, you only need to post your question once. More than that gets annoying to some people.

Have you tried hooking up an actual device and running the test off of that? I just loaded my AVD simulator and it crashes when I click yes for push notifications as well.

Have you tried logging into your Google account on the simulator before you launch the app? You need to be logged in to receive push notifications.

It may work for zaighamhali, but it did not for me. I logged into my Google account on the virtual device itself and as soon as I click yes on push notifications it suddenly crashes.

Having some LogCat output at the time of the crash would be invaluable here. It's almost impossible to figure out what's going on without some debug data. If you could paste that here, it would be awesome! Mark

@steelflight your log suggests that your virtual device is not registered? Look at the line number 6 ... "BT_screen_splash:device is NOT registered with GCM (Google Cloud Messaging) " Also I've never seen all of those "unknown" references in the log output so I'm not sure something else is wrong too? Just some thoughts ... keep digging!
