Polished the code a little bit.
Initial sync frequency now matches with the values shown in the initial app settings.
AbstractThreadedSyncAdapter already had a context and getContext() method, therefore, it is unnecessary to hold a reference for passed context in RottenTomatoesSyncAdapter.
I was passing a wrong content uri in one line of RottenTomatoesSyncAdapter. I fixed that.
Made getInstance()  method of RobotoTypefaceUtils synchronized.
