Android animation shows blank view when reverse animation added
===

I have made animation through xml like rotation animation which is to be used for activity transition. the first part is the rotate and scale animation which work togather to show half rotation the work fine but when i add reverse of them with start offset they are showing blank view instead of animation... not showing even the first part of animation which was working correctly..

Here is xml code when only first part was there and it is working correctly..

    <?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android" >
    <rotate
        android:duration="2000"
        android:fromDegrees="0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toDegrees="-15"
        android:toYScale="0.0" />

    <scale
        android:duration="2000"
        android:fromXScale="1"
        android:fromYScale="1"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="0"
        android:toYScale="1" />
      

    </set>

but when i add reverse code it just goes blank all the time...

    <?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android" >
    <rotate
        android:duration="2000"
        android:fromDegrees="0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toDegrees="-15"
        android:toYScale="0.0" />

    <scale
        android:duration="2000"
        android:fromXScale="1"
        android:fromYScale="1"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="0"
        android:toYScale="1" />
   
        
     <rotate
        android:startOffset="2000"
        android:duration="2000"
        android:fromDegrees="-15"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toDegrees="0"
        android:toYScale="0.0" />
     
      <scale
        android:startOffset="2000"
        android:duration="2000"
        android:fromXScale="0"
        android:fromYScale="1"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="1"
        android:toYScale="1" />
      

      </set>
