Call to the function:

DbxAccountManager mDbxAcctMgr = DbxAccountManager.getInstance(this.getApplicationContext(), Constants.DROPBOX_APP_KEY, Constants.DROPBOX_APP_SECRET); //error is here
toolbox.setmDbxAcctMgr(mDbxAcctMgr);

I got the library v13, dropboxsync-sdk in the project, and all the permissions and stuff on the manifest. Any idea about this?

I got the problem. I didnt had the armeabi libraries. Adding it to the libs folder fixed my problem.

From d3mon 's answer: After adding .so to libs folder: right click on project -> Properties -> Java Build Path -> "Libraries" tab -> unfold "Android Private Libraries" and edit "Native Library Location". Point to your "libs" folder.
