PRE-TEENFinalizing Design…
![Page 24: Fur Seal Data Entry A Project by Samuel Beecher. Fur Seal Data Entry Client ◦ Dr. Ward Testa ◦ Research Wildlife Biologist ◦ Works with National Marine](https://reader036.vdocuments.us/reader036/viewer/2022081603/56649e7b5503460f94b7c8a8/html5/thumbnails/24.jpg)
Pre-Teen: Finalizing DesignLots of refactoring
◦Project size grew quickly,◦Needed easier way to add new
elements without repeated code i.e. a more Object Oriented design
pattern
Produced◦New design pattern◦New database setup
![Page 25: Fur Seal Data Entry A Project by Samuel Beecher. Fur Seal Data Entry Client ◦ Dr. Ward Testa ◦ Research Wildlife Biologist ◦ Works with National Marine](https://reader036.vdocuments.us/reader036/viewer/2022081603/56649e7b5503460f94b7c8a8/html5/thumbnails/25.jpg)

Pre-Teen: Finalizing Design (cont)Not the end
◦Design changed one last time◦Found classes were getting too large
to be manageable◦Wanted to separate functionality ◦Needed addition of classes to
handle: Database access Xml Parsing Export of CSV
![Page 28: Fur Seal Data Entry A Project by Samuel Beecher. Fur Seal Data Entry Client ◦ Dr. Ward Testa ◦ Research Wildlife Biologist ◦ Works with National Marine](https://reader036.vdocuments.us/reader036/viewer/2022081603/56649e7b5503460f94b7c8a8/html5/thumbnails/28.jpg)

Pre-Teen: Finalizing Design (cont)Each Activity activates its controller
◦Android Activity Management workaround◦Slave wakes up the master….
Controller handles data validation, insertion, etc…
Activity handles all visualsModel-View-Controller Pattern
◦A parallel class hierarchyAlso used Singleton and Adapter patterns
◦dataController◦databaseController

Final UML
![Page 31: Fur Seal Data Entry A Project by Samuel Beecher. Fur Seal Data Entry Client ◦ Dr. Ward Testa ◦ Research Wildlife Biologist ◦ Works with National Marine](https://reader036.vdocuments.us/reader036/viewer/2022081603/56649e7b5503460f94b7c8a8/html5/thumbnails/31.jpg)
Final UML

Pre-Teen: Finalizing Design (cont)More to do
◦Still needed to transfer files to phone
Transfer of Data to Phone◦Mini program ran on computer◦Needed to be compatible with Mac or
Windows platform◦Parsed Excel Document, put into XML
format, transferred to phone SD card
![Page 33: Fur Seal Data Entry A Project by Samuel Beecher. Fur Seal Data Entry Client ◦ Dr. Ward Testa ◦ Research Wildlife Biologist ◦ Works with National Marine](https://reader036.vdocuments.us/reader036/viewer/2022081603/56649e7b5503460f94b7c8a8/html5/thumbnails/33.jpg)
Pre-Teen: Finalizing Design (cont)Done with design
◦Easier to add components ◦More to figure out
Algorithms for parsing Excel, Xml and insertion to database
Now just needed to implement!◦Lots of custom widgets for special
functionality

Teenager: Problems / RefactoringLearning Curve
◦First large scale project◦Fairly new to Android◦Never used SQLite◦Debugging proved really difficult
Not always clear on error
![Page 36: Fur Seal Data Entry A Project by Samuel Beecher. Fur Seal Data Entry Client ◦ Dr. Ward Testa ◦ Research Wildlife Biologist ◦ Works with National Marine](https://reader036.vdocuments.us/reader036/viewer/2022081603/56649e7b5503460f94b7c8a8/html5/thumbnails/36.jpg)
Teenager: Problems / RefactoringMisunderstandings
◦Several, all on my side of the street Tag Creation and Management
Required a change to the database design Seal Code Management
Additional Excel Parsing and insertion
Regular meetings helped, A LOT!

ConclusionLearned Much
◦First Project with a Client◦First Large Scale project◦New to Android
App contained all major features needed
Took longer than expectedHopefully will be used in the fieldWork was hard but well worth it
