    The above is basically the issue. Android EGL is successfully loading the interceptor, and it is reporting 2 errors, one that it can't parse the process mappings, and one that it can't get a handle to /vendor/lib/egl/libGLES_mali.so. The latter looks like a bug to me as it should also look in /system/lib/egl/ so I've passed this onto the team.

    Hth,
