public class WelcomeActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_welcome);

        Timer timer=new Timer();
        TimerTask timerTask=new TimerTask() {
            @Override
            public void run() {
                startActivity(new Intent(WelcomeActivity.this, MainActivity.class));
                finish();
            }
        };timer.schedule(timerTask,2000);

    }
}
