Question

I am developing an android application. In this application, I want to transition from one activity to another activity automatically after 4 seconds. I don’t know how to do this without a button.

Answer 1

This is how you can proceed:

int timeout = 4000; // make the activity visible for 4 seconds

Timer timer = new Timer();
timer.schedule(new TimerTask() {

    @Override
    public void run() {
        finish();
        Intent homepage = new Intent(Activity1.this, Activity2.class);
        startActivity(homepage);
    }
}, timeout);
