I have a very simple application that works but when i add roboguice it throws
java.lang.RuntimeException: Unable to instantiate application com.MyFirst
Well i found out what the problem was. i was using SDK v17+ and in that version external library's need te be placed in a "libs" folder and only in the libs folder. so all the tutorial's i found where they just put it in the assets folder where wrong.
Link to where i got the answer i was looking for: http://groups.google.com/group/roboguice/browse_thread/thread/474116b052050ae2
