SafeLooper
SafeLooper catches unexpected exceptions in Android applications to avoid showing force close dialog.
A normal Android application (except games) is driven by event loop, known as android.os.Looper. When you throw a uncaught exception in the main thread, the main thread's looper will stop and Android will show a force close dialog. You won't have a chance to recover the main thread's looper since it has already stopped.
If you can create a sub looper, pull message from event queue and process it with a try-catch block, you can catch the unexpected exceptions and avoid the application from crash.
Here is how a SafeLooper works:
All you need to do is import SafeLooper.java into your project and call SafeLooper.install() when your application start.
// install SafeLooper in main thread SafeLooper.install();
// receive the uncaught exception if you don't want to ignore it SafeLooper.setUncaughtExceptionHandler(...);
