does choosing new android sdk provide better performance ?

hello,
what is the best android sdk to choose.

thx.

Based on my experience I don’t think so. It’s not just Unity application any other Android app doesn’t get performance boost just by declaring random sdk-api number. since Unity Apps run on OpenGL ES you can ask Unity to run on a specific GLES api if you are using higher openGL ES shaders. It all comes down how you optimize your Unity Game-code.
