Oh my god, really? We are in 2009 again or something? Since Android 3.0, you can call setPreserveEGLContextOnPause method to prevent GLSurfaceView from releasing context, if you are targeting older version simply back-port (or use one of existing back-ports eg. the one from Replica Island).

The context  may still be lost if for example another OpenGL app runs.  The preserve context only prevents GLSurfaceView from releasing it to "play nice", it does not prevent the OpenGL driver from forcibly removing it from you if it needs the resources.

 

It's not true: driver is not allowed to forcibly remove context if it needs resources - context may be lost only due to power management events - think about deep sleep or hibernation. It's common that OS teardown process when user navigates away and given process consumes a lot of RAM you can emulate this by enabling developer option: "don't keep activities).
