Android : Android animation repeat

I have problem with animation in Android. Between End and Start of this animation blink on screen whole image with no alpha effect. Animation begin with alpha 0 and ends too with alpha 0. I have this code:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true" >

<alpha
    android:duration="4000"
    android:fromAlpha="0.0"
    android:interpolator="@android:anim/linear_interpolator"
    android:toAlpha="1.0" />

<scale
    android:duration="12000"
    android:fromXScale="0.5"
    android:fromYScale="0.5"
    android:pivotX="50%"
    android:pivotY="10%"
    android:toXScale="3"
    android:toYScale="2"
    android:interpolator="@android:anim/linear_interpolator"/>

<alpha
    android:startOffset="10000"
    android:duration="1500"
    android:fromAlpha="1.0"
    android:interpolator="@android:anim/linear_interpolator"
    android:toAlpha="0" />
</set>

and this code in java

imageView.startAnimation(animace);

animace.setAnimationListener(new Animation.AnimationListener() {
    @Override
    public void onAnimationStart(Animation animation) {
        imageView.setVisibility(View.VISIBLE);
    }

    @Override
    public void onAnimationEnd(Animation animation) {
        imageView.setVisibility(View.INVISIBLE);
        imageView.startAnimation(animace);
    }

    @Override
    public void onAnimationRepeat(Animation animation) {
    }
});
