Animate activity which is not part of your app

Question

How can I apply closing transition on activity which is not part of my app. Say, I am opening contacts app for picking contacts, I apply slide up transition when opening contacts app but closing app applies default animation (slide left).

Is there any possibility of animating it on closing too?

Answer 1

I assume when you start activity of another app (in this example it is Contacts app) you use overridePendingTransition() in your activity for the animation, something like this :

Intent intent= new Intent(Intent.ACTION_PICK,  ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, requestCode);
overridePendingTransition(R.anim.slide_in_right_to_left, android.R.anim.fade_out);

In onResume() method of your activity you can use overridePendingTransition() as well to animate activity (that is from Contacts app) from which you return:

@Override
protected void onResume() {
    overridePendingTransition(0, android.R.anim.slide_out_right);
    super.onResume();
}
