The app functions as follows:

• A single user is able to login, the user Trov/User, other users will not be able to login.
• The Trov/User is pre-populated for simplicity sake
• The server is simulated by writing to a database table called TweetServer, to better simulate a round trip to a real server a delay of 5 seconds is injected in writes to TweetServer.
• The tweets activity has the following features:
  • Tweets that have not been synced to the server show a sync icon next to them
  • If there is no network connection then tweets will not be synced to the server.
  • If a network connection is established while on this screen then tweets will be synced
  • Remember there is a five second delay so tweets sync five seconds after network connection is established.
  • Note that I would not necessarily synchronize after every tweet in a real app scenario As a minimum I would delay sending the tweets for a configurable amount of time and/or until several have accumulated. For simplicity sake in this demo, i re-sync immediately.
  • Note too that I stored a password in cleartext, for the sole purpose of simulating a server with user accounts. Normally ofcourse I would not store a password as cleartext, and instead would use AccountManager to store the password or not store the password at all and rely on a token from an authentication server, etc.

Used the following libaries:

• Butterknife, as 2 way binding is the best way to go with UIs
• Dagger - nice IOC container, instances injected nicely
• SugarOrm - ORM (Objects<-->Sqlite)
• EasyMock - mock objects for unit tests
• Junit4 - latest greatest junit version

Unit Test

• Demonstrated use of mocks (i.e. expect->run->verify) and injection of mocks.

I did not spend too much time on following:

• making the UI look really nice (i.e. just used stock android controls)
• because of time constraints did not put in stuff like SwipeRefresh (i.e. pull down refresh)
• Normally I would put all strings would be in strings.xml for localization efforts
• The targeted and minimu Android versions I just used the defaults provided when I newly created the project.

Note that I have put the apk in git in case you have problems building, needless to say normally I would not save generated files to source control
