Android Native application crashes on vrapi_EnterVrMode

We are building a native application which targets GearVR but the application just crashes(?) when calling vrapi_EnterVRMode with no real useful information.

It is running on the Samsung Note4 and our regular "plain" 2d-code path works fine. Here is the adb-logcat from our call to vrapi_EnterVrMode to the application being terminated. For all I can tell and adding extensive logging it seems to crash inside vrapi_EnterVRMode.

We set the Display, WindowSurface and ShareContext of the ovrModeParams and all calls to rendering functions including to vrapi_EnterVRMode are done from our rendering thread and we make sure to call AttachCurrentThread for the thread.

Any information or tips would be greatly appreciated.

Hi Dan, looks like its failing somewhere in eglCreateWindowSurface inside VrApi. First thought is make sure your WindowSurface is a valid ANativeWindow and that you are not yourself creating an EGLSurface from it since you are setting the VRAPI_MODE_FLAG_NATIVE_WINDOW flag.

Also, are you using native_app_glue or creating a SurfaceView in java?

I'm looking at our code (unfortunately I am not the author of the code - the author is no longer with us).

            auto vr_mode_parms = vrapi_DefaultModeParms(&_java_render);
            vr_mode_parms.Flags &= ~VRAPI_MODE_FLAG_RESET_WINDOW_FULLSCREEN;
            vr_mode_parms.Flags |= VRAPI_MODE_FLAG_ALLOW_POWER_SAVE;
            vr_mode_parms.Flags |= VRAPI_MODE_FLAG_NATIVE_WINDOW;

            auto* device = plugin_interface().render_api->device();
            vr_mode_parms.Display = reinterpret_cast<unsigned long long>(device->display);
            vr_mode_parms.WindowSurface = reinterpret_cast<unsigned long long>(device->surface);
            vr_mode_parms.ShareContext = reinterpret_cast<unsigned long long>(device->context);

We set the VRAPI_MODE_FLAG_NATIVE_WINDOW flag, but we also provide the Display, WindowSurface and ShareContext to the vrapi_EnterVrMode call.

As far as I can tell we are setting up the WindowSurface ourselves. Is this a proper way to set this up?

EDIT: The second part was actually commented out earlier with this statement:
            // Don't do this or else the ATW will try to seize the EGL rendering context in vain since it's attached to this thread
            // and it will cause an exception upon vrapi_enterVrMode

Will try without it.

What is the type of "device->surface" and where does it come from?
