How to track App-crash in Android?

I would say it is a million dollar question, since there is no call back to trace app crashes in Android. I had spent much time on figuring out this. But any how, two of my colleagues found a way to trace it (it’s great!!). Here am sharing it as a reference to all.

Step 1 :

Application class is the first to be executed during app launch. Hence we chose to track App-crash in it. The code below, returns the default exception handler that’s executed when uncaught exception terminates a thread.

Thread.UncaughtExceptionHandler defaultSystemHandler = Thread.getDefaultUncaughtExceptionHandler();

Step 2 :

The code below, sets the default uncaught exception handler. This handler is invoked in case any Thread dies due to an un handled exception.

Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
    @Override
    public void uncaughtException(Thread thread, Throwable ex) {
        try {
            System.out.println("Ouch !crashed !!!!"); // do your stuff here
            if (defaultSystemHandler != null) {
                defaultSystemHandler.uncaughtException(thread, ex); // pass the terminating thread and exception to defaultSystemHandler
            } else {
                android.os.Process.killProcess(android.os.Process.myPid()); //   kill app like iOS when crashed
            }
        } catch (Exception e) {
            e.printStackTrace();
            defaultSystemHandler.uncaughtException(thread, ex); // pass the   terminating thread and exception to defaultSystemHandler
        }
    }
});

That’s it.!
Happy coding!
