Android will add a new developer option to enable ANGLE as the system OpenGL ES driver

Android will add a new developer option to enable ANGLE as the system OpenGL ES driver. ANGLE currently ships on Pixel not as the default OpenGL ES driver but as a data driver, but that could change in a future release.

ANGLE is an open source, cross-platform OpenGL driver that translates OpenGL ES calls to one of the hardware-supported APIs available for that platform.

Currently most Android devices ship with native OpenGL ES drivers developed by the GPU vendor.
