3. INTRODUCTION After the implementation of the Konnichiwa we had to make some changes from the architectural design that we made before What and why will be described in this document along with this a tutorial on how to install and use the program Our main focus throughout this project was testability we chose pattern for this reason and we will present our test results along with comments and problems through the development DESIGN DETAILS IMPLEMENTATION DETAILS Since we decided on using the MVC pattern we have split the architecture in three parts model view and controller The decision on using the MVC pattern is the result from the requested quality attribute testability as dividing functionality in layers makes it easier to test each part In Android the view and controller parts are more or less intertwined the XML files in res layout describes the graphical interface but its content is decided in the controller which can also be used to affect the GUI Our main controller class is Konnichiwa which is in charge of starting the application allowing the user to log in and then utilizes the NetworkHandler class to populate the model ContactList with the current contact list ContactList is an ArrayList of Contact elements which is fetched from Google s servers It then starts the UserList activity if the user is successful in logging in The Konnichiwa class also has functionality for testing the Internet connection When th
4. because of the school trip to japan and miscommunication Also there were problems with our svn this resulted to time wasted Another thing was we started implementing Smack but we didn t get it to work So we switched to aSmack and things went smoother So at the end of this iteration we had to sacrifice some functionality to make the ends meet A lesson we definitely learned is that getting comfortable with new technologies SVN Android and design methods MVC and other Architectural Patterns takes more time than you think We also learned that it s important to know where our focus should lie throughout the whole implementation phase We had to scrap a lot of code due to the fact that we derailed from some of the architectural patterns we choose to use In this first version of our application the data flow didn t follow the MVC pattern But in the final revision we implemented it correctly at least we thought together with other patterns Singelton first and for most Another thing we realized is that Singelton makes sharing data with other classes a lot easier One of our security scenarios was have penetration test we didn t have enough time to implement excessive security or test for it In the midst of development we had to make changes on how the application should behave and work and this has made many of our scenarios meaningless Though the application has more or less the same functionality
