Load ANGLE from APK
Allow using ANGLE for GLES instead of native libraries.
To enable this, we also pass a handle to vendor libEGL
to use in GLES backend. A new GLAttrib is added to
facilitate this: EGL_PLATFORM_ANGLE_EGL_HANDLE_ANGLE. To
facilitate this, we are adding eglext_angle.h to the tree
from ANGLE revision: 57ff6f95
If a namespace is provided, it will be used to find ANGLE.
This should be the default route for most applications.
The namespace will point to the system ANGLE unless an update
has been applied, then it will point to the update.
To install system version:
adb root
adb shell mkdir -p /system/app/ANGLEPrebuilt
adb push ANGLEPrebuilt.apk /system/app/ANGLEPrebuilt/ANGLEPrebuilt.apk
adb reboot
To install update version:
adb install ANGLEPrebuilt.apk
To invoke with APK based apps:
adb shell settings put global angle_enabled_app <package-name>
Test: Manual (calculator, copyTexImage)
