/**
* A simple GLSurfaceView sub-class that demonstrate how to perform
* OpenGL ES 2.0 rendering into a GL Surface. Note the following important
* details:
*
* - The class must use a custom context factory to enable 2.0 rendering.
* See ContextFactory class definition below.
*
* - The class must use a custom EGLConfigChooser to be able to select
* an EGLConfig that supports 2.0. This is done by providing a config
* specification to eglChooseConfig() that has the attribute
* EGL10.ELG_RENDERABLE_TYPE containing the EGL_OPENGL_ES2_BIT flag
* set. See ConfigChooser class definition below.
*
* - The class must select the surface's format, then choose an EGLConfig
* that matches it exactly (with regards to red/green/blue/alpha channels
* bit depths). Failure to do so would result in an EGL_BAD_MATCH error.

- robert58832014-06-11有错误。Native API找不到。花我这么多分,郁闷。加个说明怎么改吧
- linqingchi82014-12-05不好用啊,没什么内容
- ada8504112015-01-30init 和step 这两个函数在什么地方?native中没有啊 还我的分
