Crashlytics Android SDK - custom UncaughtExceptionHandler

Question

Is it possible to incorporate custom UncaughtExceptionHandler along with crashlytics in one application? If yes - how?

Answer 1

Yes, it is possible.

In your Application class:

@Override
public void onCreate() {
    super.onCreate();
    Crashlytics.start(this);
    initUncaughtExceptionHandler();
}

private void initUncaughtExceptionHandler() {
    final ScheduledThreadPoolExecutor c = new ScheduledThreadPoolExecutor(1);
    c.schedule(new Runnable() {
        @Override
        public void run() {
            final UncaughtExceptionHandler defaultHandler = Thread.getDefaultUncaughtExceptionHandler();
            Thread.setDefaultUncaughtExceptionHandler(new UncaughtExceptionHandler() {
                @Override
                public void uncaughtException(Thread paramThread, Throwable paramThrowable) {
                    // do my amazing stuff here 
                    System.err.println("Error!");
                    //then pass the job to the previous handler
                    defaultHandler.uncaughtException(paramThread, paramThrowable);
                }
            });
        }
    }, 5, TimeUnit.SECONDS);
}

The reason I'm scheduling this after 5 seconds is because Crashlytics needs some time to set up his stuff. I'm using this code and it works perfectly. Of course if your app crashes on start, sorry but no custom handler ;)
