Android Studio - Emulator - eglSurfaceAttrib not implemented

Question

I have created an application with android studio, never change a single word in any file.

when trying to run it on the emulator I got the following error:

W/EGL_emulation﹕ eglSurfaceAttrib not implemented
W/OpenGLRenderer﹕ Failed to set EGL_SWAP_BEHAVIOR on surface 0xa6c1ace0,error=EGL_SUCCESS
I/Choreographer﹕ Skipped 45 frames!  The application may be doing too much work on its main thread.
W/EGL_emulation﹕ eglSurfaceAttrib not implemented
W/OpenGLRenderer﹕ Failed to set EGL_SWAP_BEHAVIOR on surface 0xa6c1ace0, error=EGL_SUCCESS

I am not getting the same problem when I run it on a real device:

W/IInputConnectionWrapper﹕ getExtractedText on inactive InputConnection
W/IInputConnectionWrapper﹕ getTextBeforeCursor on inactive InputConnection
W/IInputConnectionWrapper﹕ getSelectedText on inactive InputConnection
W/IInputConnectionWrapper﹕ getTextAfterCursor on inactive InputConnection
W/art﹕ Before Android 4.1, method int android.support.v7.internal.widget.ListViewCompat.lookForSelectablePosition(int, boolean) would have incorrectly overridden the package-private method in android.widget.ListView

Answer 1

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!
