Hello guys
am totally new to java development but I red some tutorial on web on how to create different application on Android Studio.
I've created simple webview application with navigation drawer and everything work perfect, when I tried to add Parse.com SDK to use notification service my program crashes whenever I send a push notification.
if I opened the application and send push it will Recieve it no crash in app, the problem occurs only when application is closed.
