Frage
after following numbers tutorial on how to create push notifications, yesterday I created the apk with eclipse, I installed it on my device and notifications worked. Both the server and the client. This morning tried again and it gives me the error: "key expired"! I have uninstalled and reinstalled the app and it immediately worked. The app must establish a system to counteract this. Help me!
