I have a problem with the Stereo Rendering sample on the ODG R7. I'm using Android Studio 3.0.1 and Vuforia SDK 7.0.43. The app compiles and runs correctly, but the behaviour is not the one I expect: in fact, there's no stereo rendering, but just the roadrunner email "normal" rendering (background is black, and both eyes have english news capread the same view), and the ImageTarget feature works correctly. From the Logcat, there's a red line that says: "E/AR: ODGR7Controller: ODG Display control: Cannot change display mode, there are no SurfaceViews created." The next line says "D/AR: RenderManager: Could not retrieve a valid GLSurfaceView in view hierarchy, therefore cannot set any render mode"
How can I solve this problem? Thanks in advance.
