Nit: don't really need a member, just call AccountTrackerService.get(mContext)
here directly?

Acknowledged. Just make it align with OAuth2TokenService and so on. Also make
class dependency a little bit clear to get the instance in SigninHelper
constructor. 

+
             // Account details have changed so inform the token service that credentials
             // should now be available.
             mOAuth2TokenService.validateAccounts(mContext, false);
