A) create an EGL instance

Egl10 megl = (egl10) eglcontext. getegl ();

B) Create an egldisplay instance.

Egldisplay megldisplay = megl. eglgetdisplay (egl10.egl _ default_display );

C) initialize egldisplay

Megl. eglinitialize (megldisplay, version );

D) select Config.

Megl. eglchooseconfig (megldisplay, configspec, configs, 1, num_config );

Eglconfig meglconfig = configs [0];

E) Create an OpenGL Runtime Environment

Eglcontext meglcontext = megl. eglcreatecontext (megldisplay,

Meglconfig,

Egl10.egl _ no_context,

Null );

F) Create a New Surface

Meglsurface = megl. eglcreatewindowsurface (megldisplay,

Meglconfig, holder, null );

G) set the opengles environment to the current

Megl. eglmakecurrent (megldisplay, meglsurface, meglsurface,

Meglcontext );

H) obtain the current opengles canvas

GL = meglcontext. getgl ();

I) display the drawing result to the screen

Megl. eglswapbuffers (megldisplay, meglsurface );
