How to manage files permission with SVN in Android

view story

http://stackoverflow.com – We are developing an Android application in java, using SVN as revision control system. I want some source files don't be shared. That is, I don't want that every developer has all source files, else it only should have the files he is working in. But I want this source files were uploaded to SVN manager. The problem is all source files are necessary to run the app in the emulator. In Embarcadero Delphi, I could give them only .dcu files (precompiled files), and then, they only has the source files I let them. I don't know how could I do it in Android, and How should I manage it with SVN. (HowTos)
