The account Manager is now complete. I have made it as an Android library, that can be used in any other projects too.
It will keep your account synced up and ready to go.
If you use the code, please change the Constants class to reflect your own API creds, as there is a chance that the current creds may hit limits if we all use the same thing.
Any bugs, please do let me know!
