Well i have a device which supports OpenGl ES 2.0 (HTC Desire), and of course deploy app on device much faster then on emulator. Default android emulator does not support 2.
As of Feb 2017, emulator 25.3.0 supports OpenGL 2.0 fully.

Fully GLES 2.0 compliant. Given a host GPU that has conformant desktop OpenGL drivers, the emulator now passes 100% of CTS dEQP-GLES2 must-pass.
After it stabilizes, assuming there are no critical bugs with it, you should be able to test with it.
