Android Animation - String types not allowed

Question

I created an animation resource for my app, however when building it claims that " string types are not allowed " for all of the attributes. I'm compiling at sdk 20 with a min of 14 and target of 20.

score_animation.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/accelerate_decelerate_interpolator"
    android:shareInterpolator="true"
    android:ordering="sequentially">
    <set>
        <alpha
            android:duration="300"
            android:fromAlpha="0f"
            android:toAlpha="1f" />
        <scale
            android:duration="300"
            android:fromXScale="0.4f"
            android:fromYScale="0.4f"
            android:pivotX="50%"
            android:pivotY="50%"
            android:toXScale="1.0f"
            android:toYScale="1.0f" />

    </set>
    <alpha
        android:duration="300"
        android:fromAlpha="1f"
        android:startOffset="600"
        android:toAlpha="0f" />
</set>

Full error:

Answer 1

Silly me! Turns out that it does not like the appended f so removing them ( 1.0f to 1.0 etc) solved the problem.
