I'm on a Windows 7 PC. When I run the Android emulator from Android Studio on the command line, I get this error:
Failed on eglChooseConfig
Could not initialize emulated framebuffer
I can fix it by selecting software rendering, but that's really slow, and the GPU emulation was working a couple days before; it just suddenly stopped working.
I've tried changing it not to use multi-core CPU since it's labelled experimental, but I get the same problem.
Update: I just upgraded from AS 2.3.3 to 3.0.1. It installed a bunch of new emulator software, and I still get the same error.
