问题
I'd like to use glBeginQuery(GL_TIME_ELAPSED,query) in OpenGLES, so I found out that this can be done using this extension: EXT_disjoint_timer_query and only OpenGL ES 2.0 or greater is required. My device is a Nexus 4 and I found here that it supports this extension. But when I use String extensions = GLES20.glGetString(GLES20.GL_EXTENSIONS);, I can't see this extension avaiable there. Do you know what could be the problem?
Thanks!
