EGL initialized failed

Question

Hello Everybody,

I used a SurfaceView and EGL to render my 3D contents. When I press BACK and return my activity, the activity's 3D objects become to white.

The reason is when the original activity(3D activity) resume, EGL would initialize again. So EGL would initialize and destroy everytime when different activities switch. I am not sure if the problem is EGL initialize twice... but I did initialize and destroy EGL correctly.

Anybody have this problem ? Have any solutions about this ??

Thank you so much
