need modify uploadpicture class:
extract field variable:
string path = mpath + mfile.getname();put snippet onpostexecute method in upload successful case:
dropboxapi.entry filesinpath = mapi.metadata(path, 1, null, true, null); // basing on provided code, 1 file uploaded dropboxapi.entry uploadedfile = entries.contents.get(0); string shareurl = mapi.share(uploadedfile.path).url;
after manipulations shareurl variable contain sharing link image.
