    this.close();

Answer 1

Use AlarmManager to schedule events to run at a future time.

Answer 2

It's quite simple. You have to start this task in background using Service. To make delay you can use AlarmManager. Here is example

or handler

new Handler().postDelayed(new Runnable() {

    public void run() {
        Intent intent = new Intent("INTENT_WAKEUP_B");
                        intent.putExtra("EXTRA_MESSAGE",message);
                        sendBroadcast(intent);
    }
}, timeToWait * 1000); // * 1000 if timeToWait is in seconds
