Use ObjectAnimator and BlurView together then UI frames drop a lot.

[imknown]

Activity has one BlurView. I show some Views by using ObjectAnimator. Frames drop too many.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/colors">

    <com.github.mmin18.widget.RealtimeBlurView
        android:id="@+id/blurView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:visibility="gone"
        app:realtimeBlurRadius="10dp"
        app:realtimeOverlayColor="#BB000000" />

    <Button
        android:id="@+id/source"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="30dp"
        android:background="@drawable/shape_circle"
        android:text="＋"
        android:textSize="50sp" />

</RelativeLayout>

private void doExpandAnim() {
    blurView.setVisibility(View.VISIBLE);

    PropertyValuesHolder z1 = PropertyValuesHolder.ofFloat("alpha", 0, 1);
    ObjectAnimator z = ObjectAnimator.ofPropertyValuesHolder(blurView, z1);
    z.setInterpolator(new LinearInterpolator());
    z.setDuration(350);

    PropertyValuesHolder c1 = PropertyValuesHolder.ofFloat("rotation", 0, 360 + 45);
    ObjectAnimator c = ObjectAnimator.ofPropertyValuesHolder(source, c1);
    c.setDuration(350);

    AnimatorSet animatorSet = new AnimatorSet();
    animatorSet.playTogether(z, c);
    animatorSet.start();
}

private void doCollapseAnim() {
    PropertyValuesHolder z1 = PropertyValuesHolder.ofFloat("alpha", 1, 0);
    ObjectAnimator z = ObjectAnimator.ofPropertyValuesHolder(blurView, z1);
    z.setInterpolator(new LinearInterpolator());
    z.setDuration(350);
    z.addListener(new AnimatorListenerAdapter() {
        @Override
        public void onAnimationEnd(Animator animation) {
            blurView.setVisibility(View.GONE);
        }
    });

    PropertyValuesHolder c1 = PropertyValuesHolder.ofFloat("rotation", 360 + 45, 0);
    ObjectAnimator c = ObjectAnimator.ofPropertyValuesHolder(source, c1);
    c.setDuration(350);

    AnimatorSet animatorSet = new AnimatorSet();
    animatorSet.playTogether(z, c);
    animatorSet.start();
}

But using PopupWindow / Dialog does not have this problem.

Can't reproduce. I'm testing on a galaxy s3 phone. Add some buttons under the blur view.

WOW!! THX A LOT!! You are right!!

I find that i closed the hardware accelerated for this.

I should NOT use at all:

android:hardwareAccelerated="false"

and

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEA
    getWindow().setFlags(
        WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED,
        WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED);
}

use these instead:

myView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
