Android: How to start an activity from an UncaughtExceptionHandler set in application

How to start activity from UncaughtExceptionHandler if this is main thread crashed?

My goal is to display some error messages when my Android program crashes.

I have an uncaught exception handler registered in my program's application (MyApplication) onCreate:

Thread.setDefaultUncaughtExceptionHandler(new HelloUncaughtExceptionHandler());

And when an exception is caught, I'd like to start a new activity for the user to save/submit bugs. This is what I am currently doing:

class HelloUncaughtExceptionHandler implements UncaughtExceptionHandler {
    @Override
    public void uncaughtException(Thread thread, Throwable e) {
        final Writer result = new StringWriter();
        final PrintWriter printWriter = new PrintWriter(result);
        e.printStackTrace(printWriter);
        String stacktrace = result.toString();
        printWriter.close();

        Intent intent = new Intent(MyApplication.this,
                BugReportActivity.class);
        intent.putExtra("stacktrace", stacktrace);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
    }
}

I am getting a blank screen without BugReportActivity showing up (if I start it from an activity it works fine). The "MyApplication.this" worries me... is there really no way to launch an arbitrary activity from my application?

Thanks all.
