"libesl called unimplement opengl es API"

I tried to make a demo of opengles 2.0 by using android ndk,

Logcat showed the error information "libesl called unimplement opengl es API".

Why?

I'm following OpenGL ES 2.0 Programming Guide's first exa开发者_如何转开发mple.

Regards,

Did you run it in the emulator or on a proper Android device? The emulator doesn't support OpenGL at all!

You may want to check this answer:

Android: GLES20: Called unimplemented OpenGL ES API

In a nutshell, the application needs to be told to use OpenGLES 2.0.

You could start with the hello-gl2 sample in the NDK. The Java-side setup looks a bit complicated but does the job.
