Re: [android-developers] Transition from the end of an animation to a new Activity?

Aside from whatever bug you have, for animations across activities you will probably get a much better result by using window/activity animations:

http://developer.android.com/reference/android/app/Activity.html#overridePendingTransition(int, int)

API demo:

(whoops just noticed the comment for that class is wrong.)

I am trying to make my application transition to the MenuActivity(main
menu) and the end the SplashActivity(splash screen) once the fade2
animation has finished, but instead of this happening my app force
closes after the SplashActivity ends. I think that my error lies in
the "onAnimationStart" and "onAnimationRepeat" lines but I am unsure.
What can I fix in my code?

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.view.animation.Animation.AnimationListener;
import android.widget.ImageView;
import android.widget.TextView;

public class SplashActivity extends Activity {
       TextView maker, motto;
       ImageView ball;
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.splash);

       maker = (TextView)findViewById(R.id.dev);
       Animation fade1 = AnimationUtils.loadAnimation(this,
R.anim.fade_in);
       maker.startAnimation(fade1);

       ball = (ImageView)findViewById(R.id.Ball);
       Animation customAnim = AnimationUtils.loadAnimation(this,
R.anim.custom_anim);
       ball.startAnimation(customAnim);

       motto = (TextView)findViewById(R.id.motto);
       Animation fade2 = AnimationUtils.loadAnimation(this,
R.anim.fade_in2);
       motto.startAnimation(fade2);


       fade2.setAnimationListener(new AnimationListener() {
               public void onAnimationEnd(Animation animation) {
               startActivity(new Intent(SplashActivity.this,
               MenuActivity.class));
               SplashActivity.this.finish();
               }

                       @Override
                       public void onAnimationRepeat(Animation animation) {
                               // TODO Auto-generated method stub

                       }

                       @Override
                       public void onAnimationStart(Animation animation) {
                               // TODO Auto-generated method stub

                       }


               });
       }
}
