Sorry about that.

Are you testing it on a real device? It fails to load the native (C++) library.

Yes Erel,

It have been tested on 4 different real device:
HUAWEI VNS-L21, ARM64-v8a (64-bit) - (FAILS)
LGE LG-H815, ARM64-v8a (64-bit) - (FAILS)
HTC Desire 601, armeabi-v7a (32-bit) - (WORKS)
Prestigio PMP5770D, armeabi-v7a, armeabi (32-bit) - (WORKS)

and BlueStacks Android Emulator:
SAMSUNG-SM-N900A x86, armeabi-v7a (32-bit) - (WORKS)

My conclusion is that the conflict is generated on 64-bit devices and fails to load .so library
After research I found this:
https://stackoverflow.com/questions...es-on-64-bit-android-device/30799825#30799825

If so, is there way to workaround this and force 32-bit native libraries on 64-bit Android device using B4A.

Open the compiled APK with 7zip or a similar tool. Which folders and files do you see inside the lib folder?

BTW, you should test XUI2D.

libopenslplayer.so is missing from folders:

\lib\arm64-v8a

• libgdx.so
• libgdx-box2d.so
• libgdx-freetype.so

\lib\armeabi

• libgdx.so
• libgdx-box2d.so
• libgdx-freetype.so
• libopenslplayer.so

\lib\armeabi-v7a

• libgdx.so
• libgdx-box2d.so
• libgdx-freetype.so
• libopenslplayer.so

\lib\x86

• libgdx.so
• libgdx-box2d.so
• libgdx-freetype.so

\lib\x86_64

• libgdx.so
• libgdx-box2d.so
• libgdx-freetype.so

Basically I just need some good graphics library to rotate 1 image (wheel) at constant rate of 60 FPS.
I tried GameView Lib with timer but that wasn't so smooth on all devices.

Then I moved to LibGDX and animation is great but having conflict with other libraries.
So you are saying its easier to move on XUI2D than try to fix this conflict?

GameView is no longer relevant.

XUI2D is a good option. It is also cross platform.

About the error, you can delete all of the folders except of armeabi (from the library jar). It will then work.

Thank you Erel, after deleting it works on all tested phones.
BTW i saved 2MB
So, no phone will be impacted with deleting this folders?

No. However starting from August 2019 all native libraries must also include 64 bit libraries: https://android-developers.googleblog.com/2017/12/improving-app-security-and-performance.html
