Still I want you to learn Android first from some good tutorials. But I can guide you how you can achieve this.

• You will make a Service . Which will run in background.
• You will make a Handler in your service. That will call postDelayed() method.

Like this

final Runnable r = new Runnable() {
    public void run() {
        changeActivity(); // make this method & add your logic of checking current activity & setting new
    }
};

handler.postDelayed(r, 1000); // 1000 is millisecond, you will set time here.
