overridePendingTransition() method does not work for when we move the activities on Back key press?

I have 3 activities A,B,C.I am able to show the animations when move the activity from A->B->C.

I want to add the animation when I press the back buton.

I am using overridePendingTransition(R.anim.fadein,R.anim.fadeout) on onCreate() method.

Can some one explain how it works when i pressed the back button?

Override your activity's onBackPressed

public void onBackPressed() {
        super.onBackPressed();
        overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
}

You have to override back button:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) 
{
    if (keyCode == KeyEvent.KEYCODE_BACK) 
    {
        finish();
        overridePendingTransition(R.anim.anim_out, R.anim.anim_in);
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

For exammple: Create "anim" folder in res and add: anim_out:

<?xml version="1.0" encoding="UTF-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
        <alpha
        android:fromAlpha="1.0"
        android:toAlpha="0.0"
        android:duration="500" />
</set>

anim_in:

<?xml version="1.0" encoding="UTF-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
        <alpha
        android:fromAlpha="0.0"
        android:toAlpha="1.0"
        android:duration="500" />
</set>
