i got library v13, dropboxsync-sdk in project, , permissions , stuff on manifest. idea this?

i got problem. didnt had armeabi libraries. adding libs folder fixed problem.

from d3mon 's answer: after adding .so libs folder: right click on project -> properties -> java build path -> "libraries" tab -> unfold "android private libraries" , edit "native library location". point "libs" folder.
