Global method to prevent app from crashing?

I am trying to add a method in my parent activity that all my activities are inheriting from. I want the method to catch any errors that have not already been handled so the app does not crash. Instead of crashing it will redirect to a failure screen activity.

Here is what I have at the moment but it does not work, the app freezes and then goes black:

Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
        @Override
        public void uncaughtException(Thread paramThread, Throwable paramThrowable) {
            redirectToFailureScreen();
        }
    });

The uncaught exception handler is not meant for rescuing an application. Ending up in that handler means the thread is being terminated. The handler gets notified as a courtesy for logging purposes before the thread is killed.

Implemented by objects that want to handle cases where a thread is being terminated by an uncaught exception. Upon such termination, the handler is notified of the terminating thread and causal exception. If there is no explicit handler set then the thread's group is the default handler.
