Android Studio – Emulator – eglSurfaceAttrib not implemented
I’ve found the same thing, but only on emulators that have the Use Host GPU setting ticked. Try turning that off, you’ll no longer see those warnings (and the emulator will run horribly, horribly slowly..) In my experience those warnings are harmless. Notice that the “error” is EGL_SUCCESS, which would seem to indicate no error at all!
