Fur Seal Data EntryA Project by Samuel Beecher

Fur Seal Data EntryClient

◦Dr. Ward Testa◦Research Wildlife Biologist◦Works with National Marine Mammal

Laboratories

Project◦Data Entry App ◦Motorola Defy (Android 2.0 Update 1)

HISTORYIn the beginning was…

History: Where it BeganDesignated as depleted in 1988

◦National Marine Fisheries Service

More specific monitoring after 2000◦National Marine Mammal Laboratory

History: Where it Began (cont)Done on Pribilof Islands

Archipelago ◦St. Paul and St. George◦70% of total Fur Seal Population

globally

History: What it Looked LikeTrack population composition:

◦Size◦Age◦Sex◦Natural Mortality

Performed Observations◦Summer months◦Process needs to be accurate

Used for statistics

History: What it Looked Like (cont)

History: What it Looked Like (cont)Codes are important

◦Visibility ( 1 - 3◦Pup (0 – 5)◦Age (P, J, A)◦Loss (0 – 6)

Used for easy reference and writing◦Cheat sheet on back of printed form

Used in Excel Sheet◦Statistics and entry

History: What it Looked Like (cont)Entered into an Excel

Spreadsheet◦Used to create statistical data

History: What it Looked Like (cont)Also done by performing

“Counts”◦Summer months

Pad and Paper

Entered into Excel Spreadsheet

PROJECT GROWTHFrom birth to adulthood…

The Growth of a ProjectBirth

◦Initial SpecificationsToddler

◦DesignPre-Teen

◦Finalizing DesignTeenager

◦Problems and RefactoringAdult

◦Final Touches

BIRTHInitial Specifications…

Birth: Initial SpecificationsClient Specifications: Observations

◦Check IDLookup table for consistency Tag Side, color, type, and number

◦Insert new record, or Edit previous record

◦Check plausibility of Tag Type / Color combo

◦Check plausibility of Island / Rookery / Section combo

Birth: Initial Specifications (cont)Additional Specifications:

Observations◦Lookup table of all observations for

that day◦Dynamic Island, Rookery, Section,

Tag Types, Tag Colors, and all codes I.e. they can’t be hardcoded There must be a centralized place to

manage and transfer data to phone◦Transfer IDLookup spreadsheet to

Phone

Birth: Initial Specifications (cont)Client Specifications: Counts

◦Counters for Females, pups, harem bulls, territorial bulls, and lone bulls

◦Harem Bulls must have femalesAdditional Specifications: Counts

◦Counters for dead adults, bulls, females and pups

◦Lookup table of all previous counts for that day

◦Ability to enter “negative” counts

Birth: Initial Specifications (cont)Client Specifications: General

◦Export counts, observations to CSV◦Move CSV from phone to computer

Additional Specifications: General◦Export count totals in a separate CSV

Birth: Initial Specifications (cont)Design Environment

◦Started with MotoDev for Eclipse◦Switched to NBAndroid for Netbeans

Schedule◦Planned for 8 hours a week◦Spent much more

TODDLERInitial Design…

Toddler: DesignPrototyping

◦Convenient for working on Android◦First large scale project

First Design Ideas◦Based on initial specifications◦Changed drastically by the end

PRE-TEENFinalizing Design…

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

patternProduced

◦New design pattern◦New database setup

Pre-Teen: Finalizing Design (cont)

Pre-Teen: Finalizing Design (cont)

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

Pre-Teen: Finalizing Design (cont)

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

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

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

TEENAGERProblems and Refactoring…

Teenager: Problems / RefactoringLearning Curve

◦First large scale project◦Fairly new to Android◦Never used SQLite◦Debugging proved really difficult

Not always clear on error

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 insertionRegular meetings helped, A LOT!

ADULTReview…

Adult: ReviewPlanned 8 hours per week

◦Actual roughly 20 - 22 per week

Still working on bugs◦Dr. Testa is working with phone

CONCLUSIONTo Conclude…

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
