GLSurfaceView causing ANR after activity is destroyed

Question

I have an Activity containing a GLSurfaceView. When I hit the back button to go the previous Activity, it manages to show that Activity, but the screen is then unresponsive and will eventually ANR.

Here is the onSurfaceCreated() code:

-EDIT-

If I move the mSurfaceView.onPause(); to the owner fragment's onPause() then the app does not freeze after backing out of the fragment, but it will usually crash silently (no force close) a few seconds after backing out of the fragment.

@Override
public void onSurfaceCreated(GL10 gl, EGLConfig config) {
    if (mOpenGlesVersion == OPENGLES_VERSION_10) mOpenGles = new OpenGles10();
    else if (mOpenGlesVersion == OPENGLES_VERSION_11) mOpenGles = new OpenGles11();
    else if (mOpenGlesVersion == OPENGLES_VERSION_20) mOpenGles = new OpenGles20();

    // Let the caller know the surface has been created.
    if (mListener != null) mListener.onGLSurfaceViewCreated();
    // No intention of drawing anything, just gathering info.
    mSurfaceView.onPause();
}

This is the logging info taken from /data/anr/traces.txt: (There are two lines that got messed up because of --MORE--)

Answer 1

This is a known bug in GLSurfaceView. This is due to having more than a single live GLSurfaceView in your app. I've tried the suggested fix (look at the previous link), but ended having to redesign my app to dispose GLSurfaceView instances manually.

My trick was to call removeView() on the GLSurfaceView's parent, thus causing its םnDetachedAFromView() event to be fired.

This is less than optimal, but that's life.

(B.T.W. a refrence for future Googlers - in my app the culprit was ArcGIS's MapView).

Your Graphics.onSurfaceCreated() invoked GLSurfaceView.onPause(). You should not invoke onPause or you meet a dead lock. onPause() will invoke wait() and your surfaceDestroyed() will invoke wait().
