[Android (C) and HTML5 (JS)] GPU skinning "too many uniforms" crash on android Adreno while fine on Mali GPU

Does anyone came across to this error with armory and know what is actually causing this issue?

I suspect my 3d model is too complex and I am searching after some directions in order to run it correctly in Armory and making it more simple.

What is a "uniform" and how does it translate in Blender?

Any input will be much appreciated.
Thanks

The report concerns GPU skinning, an Adreno Android crash, HTML5/JS, and a Blender model, but names no files, tests, or entry points. Start by reproducing the uniform-limit failure on Adreno and comparing it with Mali; done would require a confirmed cause and a documented way to run the model without the crash.
