private static int WELCOME_TIMEOUT = 4000;
@OverRide
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);;
setContentView(R.layout.activity_main);
new Handler().postDelayed(new Runnable () {
@OverRide
public void run() {
Intent welcome = new Intent (MainActivity.this, SecondActivity.class);
startActivity(welcome);
overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
finish();
}
}, WELCOME_TIMEOUT);
}
}

other way to write the code and include fade in and out without button and should be circle transition fade out settings
