How to change all the activity transitions at once in Android application?

Question

I know I can change activity transition using the following code right after startActivity() or finish()

activity.overridePendingTransition(R.anim.activity_clo

Answer 1

Step 1: Create one base activity

Step 2: Extend all your activity to this base activity

Step 3: In your base activity add following code

@Override
protected void onStart() {
super.onStart();
overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
}

@Override
protected void onPause() {
super.onPause();
if (isFinishing()) {
    overridePendingTransition(android.R.anim.fade_in,android.R.anim.fade_out);
 }
}
