  2. Goals for the week - Test the data base for usability SQLlite Memory Leak Detection

  3. SQLite • SQLite databases can only be supported with a max filesize of 4.5 MB. • SQLite databases are local to the application in Android and doesn’t handle well with inter-application linking. • To examine the database you want to use the Android Debug Bridge • Through shell, you can reference the tag and check the database. • Example – sqlite3 database.db • Please refer to - http://www.screaming-penguin.com/node/7742 for an amazing tutorial

  4. Memory Leaks • The biggest hurdle while developing applications is MEMORY LEAKS. • They’re lines in your code that cause the following: • Your program uses memory that it is unable to release, which becomes a vicious cycle. • Your program will keep eating more and more memory and will keep accessing the ‘ram’ and will keep using up the battery and slowly it will drain your phone of the battery and crash its OS. • If you see the ‘Application Crashed’ message its PROBABLY a memory leak. • Read about it here - http://groups.google.com/group/android-porting/browse_thread/thread/9c84baa10cebbb68?pli=1 • Andhttp://developer.android.com/resources/articles/avoiding-memory-leaks.html

  5. The UI • The UI is almost complete. Some minor changes required once the database is linked (we still need the floor plansof the MSEE and EE buildings). • Once the plansare acquired, the arrays for the buildings and floors will be completed. • The plans will then be uploaded into the database and arrays in the UI will be modified. • DONE!

  6. Next four weeks – Complete the database – We currently have a memory leak occurring in the algorithm for the database. Needs to be fixed. Need to fix some non-java related errors – eclipse and recognizing android on some machines. Modify the UI to fit – Once the aforementioned errors have been fixed, we will need the floor plans (Prof. Allebach and Prof. Delp!!!!). Once the floor plans have been acquired, we need to add the buildings and floors to the user interface.
