How to prevent android app from crashing due to exception in background thread?

Question

It\'s a general question, which raised from specific scenario, but I\'d like to get a general answer how to deal with the following situation:

Background:

Answer 1

As mentioned above, Thread.setDefaultUncaughtExceptionHandler is the proper way to handle this. Create the class:

 private class MyThreadUncaughtExceptionHandler implements Thread.UncaughtExceptionHandler {

    @Override
    public void uncaughtException(Thread thread, Throwable ex) {
        Log.e(TAG, "Received exception '" + ex.getMessage() + "' from thread " + thread.getName(), ex);
    }
}

Then call setDefaultUncaughtExceptionHandler from your main thread:

 Thread t = Thread.currentThread();
 t.setDefaultUncaughtExceptionHandler(new MyThreadUncaughtExceptionHandler());
