I don't really know what the difference is between : Container, View and Appui.
If you have an idea....

I would like to make an application where I have a Camera, the displaying of the last picture taken, a processing on this image, the displaying of the result and the possibility to send in MMS.
I think that only one view is necessary and I don't understand what the container is.
Could you help me please.

Thanks in advance.
