I did to export the main folder to the jar and use it as a library in my project. From the Android client folder, I use the camera package and most of the classes from the client.android package (there is only one action left, captureActivity). I uninstalled the encode, history, result, share and wifi package and deleted any links of these packages in the camera or android package.
I took the remaining classes (camera classes and androids) and I included them in my project
thanks
