getLatestVersion method doesn't work

[Mannyrf]

This method always returns nothing and doesn't seem to work. Furthermore, according to CafeBaazar documents, "getVersionCode" must get PackageName as parameters but "getLatestVersion" doesn't have any input parameter, and PackageName not specified before calling.

From cafebazaar check for update document:
long vCode = service.getVersionCode("packagename");
