I'am using OpenGL ES 2.0 on android and trying to enable alpha to coverage.

glEnable(GL_SAMPLE_ALPHA_TO_COVERAGE);

But it doesn't give any effect as I expect. The same code works well on windows and linux desktops.

Is the alpha to coverage supported on android devices? May be I need to enable some additional options?

Have you tried this with more than one device? Some devices might not support it. – EDD Jan 23 '17 at 11:13
Yes, I've tried with few other devices. It didn't work. Is it possible to check if the device supports this feature? – Dmitry Jan 23 '17 at 11:17

Do you have MSAA enabled in your app ? Alpha to coverage only makes sense if you are using anti aliasing. – VB_overflow Jan 25 '17 at 10:18
Enabling multisampling fixed it. Thanks a lot. – Dmitry Jan 25 '17 at 13:16
