This is not the issue, you must have something wrong with your code, this is supposedly a warning and not an indication of a serious thing. if you're on an emulator enable useHostGpu & add
<uses-feature android:glEsVersion="0x00020000" android:required="true" />
In your Manifest File
0x00020000 = OpenGles 2.0 (API >=8)
0x00020000 = OpenGles 3.0 (API >=18)
This will force android studio to use a specific OpenGles Library.
