I am encountering a strange problem and I am clueless about what to do. I try to use second technique to integrate Google VR SDK to Vuforia. I open a new project add Vuforia package and rename manifest. Then I import Google VR SDK and encounter 3 errors. I can run vuforia without the SDK with no errors. But since I want to change the stereo viewport sizes I need to integrate Google VR SDK. Does anyone has a ny idea about this? Any help is appreciated.
