Global Exception Handlers in Java

Question

I am thinking of setting up a global, default Exception handler for my (Android) Mobile application(which uses Java syntax) using Thread.setDefaultUncaughtExceptionHandler

Answer 1

One possible problem with creating a global exception handler is you may get stuck in a loop of exceptions - some exceptions will be thrown repeatedly unless a program is terminated.

If you mean that when an exception is thrown, a message is displayed then the app is terminated, then you'll be fine.

Answer 2

• The name is a bit misleading, because using that method will set a default exception handler for all threads.
• Make sure no exceptions can be thrown from your exception handler.
• If you're doing GUI stuff from your exception handler, make sure you're doing it from the right thread.
• An uncaught exception will only stop the thread where the exception took place, if that also causes the process to terminate depends on any other threads that might be running.
