I would suggest that way:

    int counter = 0;


    ....

    public void onBackPressed() {
                        counter++;
                        if(counter > 2){
                            System.exit(0);
                        }else{
                            Toast.makeText(this, "TRIPLE CLICK TO EXIT!", Toast.LENGTH_SHORT).show();  
                        }

                        final long DELAY_TIME = 3000L;
                        new Thread(new Runnable() {
                            public void run(){
                                try {
                                    Thread.sleep(DELAY_TIME);
                                    counter = 0;
                                } catch (InterruptedException e) {
                                    e.printStackTrace();
                                }
                            }
                        }).start();
}
