AndAR Camera

[Google Code Exporter]

I use the AndAR Example with other acticity

What steps will reproduce the problem?
1. First I start  AndARActivity that runs ok
2. Then, I start other activity via an options menu. The new activity runs ok 
too
3. But When I return to the AndARActivity I see that it was destroyed

What version of the product are you using? On what operating system?

I use android 2.2 with the last version of AndAR

I think that it's a problem with the camera because when i leave the 
AndARActivity I don't turn it off. When I start AndARActivity the method 
ShowPreview() initiates the camera but i don't know how to stop it.

Thx
