Animator/AnimatorSet issue on some devices

Question

I have made some tests with the ObjectAnimator class on some devices and everything is OK except for one device : Huawei P8 Lite 2017.

On this device, the View "disappears" when the animation starts and "appears" at the end. The issue appears only when I'm using AnimatorSet/Animator (Java code or XML), but animations which use the old Animation class (TranslateAnimation, AlphaAnimation...) are working well.

Here is the list of devices where there is no issue : Nexus 5 Nexus 5X Nexus 9 HTC One M9 Samsung GS4 Pixel XL Alcatel OneTouch Idol 5

What is the problem with this Huawei ?

Edit : I have made some other tests, the issue seems to be only with Rotation animation.

ObjectAnimator r = ObjectAnimator.ofFloat(myView, View.ROTATION_Y, 540);
r.setDuration(5000);
r.start();

works on every devices except the Huawei.

If I replace ROTATION_Y by ALPHA or TRANSLATION_X or Y, it is working on the Huawei.

Here is a link with more or less the same issue : ObjectAnimator causes ImageView to disappear

i have no idea what `disappears` / `appears` really mean but most likely animators are disabled under `developer options` — pskink, Oct 20 '17 at 08:37
As if View.VISIBILITY = INVISIBLE. I have checked in dev options, Animation scale is on "1X" — Tonio Marco, Oct 20 '17 at 09:03
so no animations work on that phone? even those in home launcher app? — pskink, Oct 20 '17 at 09:11
Only in my app. I have tested a ObjectAnimator.ofFloat(Rotation).setDuration(1 second), the View appears, becomes invisible for 1 second, and appears at the end of the animation. This is crazy. — Tonio Marco, Oct 20 '17 at 09:14
so your `ObjectAnimator` is wrong and nobody will tell you why without your code — pskink, Oct 20 '17 at 09:16
tried: `myView.animate().setDuration(1000).rotationBy(360);`? — pskink, Oct 20 '17 at 16:16

I had the same problem with Huawei devices (P9 Lite).

The problem is "camera distance" during transformation. Default value for camera distance for Huawei is too small and you should set it by code:

image.setCameraDistance(float)

From documentation:

If you want to specify a distance that leads to visually consistent results across various densities, use the following formula:

float scale = context.getResources().getDisplayMetrics().density;
 view.setCameraDistance(distance * scale);

Thanks but set it to what? What the distance variable equals to? — Oz Shabat, Oct 20 '22 at 23:40
