How to Create a splash screen on android

Create a class called: Splash then paste this code into the flowing class

public class Splash extends Activity
{
    boolean flag = false;
    Runnable runnable;
    Handler handler;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);
        runnable = new Runnable() {
            @Override
            public void run() {
                if (!flag) {
                    final Intent mainIntent = new Intent(Splash.this, MainActivity.class);
                    Splash.this.startActivity(mainIntent);
                    Splash.this.finish();
                }
            }
        };
        handler = new Handler();
        handler.postDelayed(runnable, 5000);

    }

    @Override
    protected void onPause() {
        super.onPause();
        flag = true;
        handler.removeCallbacks(runnable);
    }

    @Override
    protected void onRestart() {
        super.onRestart();

        flag = false;
        handler.postDelayed(runnable, 1-1);
    }
}

change the replace your main class by ".Splash" (the name of class we just created) then declare a new activity with the name of de fault class you just created

finally create your activity_splash layout in the layout folder
