Viro3DObject disappear when reopen the application in the phone

[Eddie-hubb]

Now I'm using an Android phone to develop, and I found the demo called 'ARSimpleSample' has a bug. when the user has installed the app on the phone and the USB is not connected to the PC, the 3DObject will disappear if the user kills the app and reopen it. it will only show the object once after installation. Not only 'ARSimpleSample' but also 'ARDrivingCarDemo' has this problem. the car will also disappear when reopening the app. I wonder why.
