app crash when adding any android component to SceneObject

[spakanati123]

Hi, all of sudden our app started crashing on launch and the crash is happening while adding any Android component to the SceneObject. I can reproduce the issue on given demo's gvr-events as well. The crash trace is:

Requesting a quick update on this. Thanks in advance

Hi @spakanati123, Which constructor of GVRViewSceneObject are you using? What version of GVRf are your using? What branch of GVRf-Demos are you on?

[spakanati123]

@ragner seems my demo branch is old and with the updated one it's working fine. I can see API diff to register android layout in the commit: https://github.com/gearvrf/GearVRf-Demos/commit/51c5d35a528dfa7bf53cd796f2d308f4d6d846aa#diff-7bcfc0e30ec452a2b0ad5aefb0c6b022

@ragner when i am checking the gvr-videoplayer demo app the cursor not working with remote controller only in player screen when playing video(galley scene no issue) but it's working fine with track pad in player scene as well on samsung gear VR headset. This is logic i seen in demo app.

   private void initCursorController() {
        mScene.getEventReceiver().addListener(mTouchHandler);
        GVRInputManager inputManager = mContext.getInputManager();
        inputManager.selectController(new GVRInputManager.ICursorControllerSelectListener() {
            public void onCursorControllerSelected(GVRCursorController newController, GVRCursorController oldController) {
                if (oldController != null) {
                    oldController.removePickEventListener(mTouchHandler);
                }
                mCursorController = newController;
                newController.addPickEventListener(mTouchHandler);
                newController.setCursor(createCursor());
                newController.setCursorDepth(-CURSOR_DEPTH);
                newController.setCursorControl(GVRCursorController.CursorControl.CURSOR_CONSTANT_DEPTH);
            }
        });
    }

But if i use built in API gvrContext.getInputManager().selectController(); remote working fine but this API not helpful for doing any customiztion , please suggest to fix the issue on demo app gvr-videoplayer.

I am using galaxy S8 device with Samsung Gear VR headset

@spakanati123 The cursor is not working in what way? I tried and it works pretty good if you use the trigger button for clicking. If you are clicking via the touch pad then there might be a problem which is a known issue. Is there any other demo app in which you experience this issue?
