Android 4.4.2 Animation Fade in and Fade out

I have an application using fade in and fade out animations. It works properly on a device which is android 4.2.2. However the same application does not show the animation on device 4.4.2. These are my xml files

res/anim/fadein.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://ift.tt/nIICcg"
android:interpolator="@android:anim/linear_interpolator" >

<alpha
    android:duration="1000"
    android:fromAlpha="0.1"
    android:toAlpha="1.0" />

res/anim/fadein.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://ift.tt/nIICcg"
android:interpolator="@android:anim/linear_interpolator" >

<alpha
    android:duration="2000"
    android:fromAlpha="1.0"
    android:toAlpha="0.1" />

And this is the place where i call fade out animation.

animationFadeOut = AnimationUtils.loadAnimation(this, R.anim.fadeout);    
aim.startAnimation(animationFadeOut);

I strongly wonder why it is ok for version 4.2.2 but not working on 4.4.2. Can you help me?

Regards
