COMMUNICATION Team 5 ADIL KHAN

COMMUNICATION Team 5 COMMUNICATION PROVIDER Two Modules Comprise the CommunicationProvider SmilTransporter CloudDataProvider Both are Singletons

COMMUNICATION Team 5 COMMUNICATION PROVIDER

COMMUNICATION Team 5 COMMUNICATION PROVIDER Steps to Transmit the SMIL Message Upload assets (Audio,Video,Image to cloud) Handled by CloudDataProvider HTTP (Apache HttpClient Library) Returns BlobStore Key

COMMUNICATION Team 5 Encode the URL of the BlobStore Key in the Smil object. Replaces local path eg: “/sdcard/chair.bmp” With Cloud path: key=AMIfv945sJ1WUX9sIqeJr_jjAS3XcWCuNH5ReIuamFOuBCtOh0TENWzk wdCcRQMVnja0Gb0xO3YeaCecac6vmV8sX5_exnxUdb1s1JBxyc62Tj1JZMkt oLH2IdnPfTtoSc4i8kie4WZbtVmgzCO4Au-RCjmwdhOLrg"

COMMUNICATION Team 5 COMMUNICATION PROVIDER Generate XML using the Simple Xml Framework’s serialize functionality

COMMUNICATION Team 5 COMMUNICATION PROVIDER Simple XML SimpleFramework Light weight alternative to JAXB. Annotate Model Classe Serialize/Deserialize from JAVA to XML and back

COMMUNICATION Team 5 COMMUNICATION PROVIDER 4. Send SMIL XML to endpoint using XMPP protocol. Conducted in the SmilTransporter class Asmack Library is used to provide high level XMPP functionality ComposerPlayer XMPP via ASMACK Library

COMMUNICATION Team 5 COMMUNICATION PROVIDER 5.Player checks for new message, using the SmilTransporter class. CloudDataProvider used to download Assets from cloud SMILMedia List generated and consumed by Player to play the file. Player

COMMUNICATION Team 5 COMMUNICATION PROVIDER Player Files Downloaded. SMIL Objects renamed with local paths Http Request for download with blob-key SimpleXML framework used to Deserialize SMIL xml to List of SMILMedia Objects and made available to the Player

CLOUD ENVIRONMENT Team 5 KEITH BROWN

CLOUD ENVIRONMENT Team 5 Cloud Platform: Google App Engine  Some familiarity  Good integration with Eclipse IDE Seemed like a logical choice for Android

Design Considerations Team 5 Considerations: Had to be able to upload and download large multimedia files.  Blobstore API provided this functionality Had a choice of developing in Python or JAVA (modified J2EE)  Chose JAVA due to familiarity and performance  JAVA would be running as a Servlet which has inherent Multi- Threading  This would be more efficient than Multi-Processing which Python would be as a CGI

Implementation Issues Team 5 Issues Overcome: The greatest challenge was conforming to the API for the Blobstore  Blobstore designed more for accessing from a web page  Getting the upload key presented a challenge  Keeping track of file types also presented a challenge Where as our app should have been able to run for free in order to use the Blobstore billing needed to be enabled.

MULTI-THREADING Team 5 Android Activities was used to handled all of the our multitasking(AsyncTask Class). God Loves passing INTENTS! Non-blocking Activity calls, like a fork Handler Class – Tried to use, found better ways

PROJECT MANAGEMENT Team 5 JIM NEILAN

Project Management – Pass/Fail What Worked – Communication – X-Programming – Text and Sites – “Day of Code” Meetings – 2 Hour Design Meetings – SVN (At the end) – Google Talk Team 5 What Didn’t – Communication – Initial Assignments – Water Fall Method – Time Management – ½ hr. Discussions – SVN Usage “Tell me and I will forget. Show me and I may remember. Involve me and I will learn” - MIT

INSPECTION Team 5 HANS HAGEN

INSPECTION - DOCUMENTS Team 5 Formal Inspection Fagan Inspection Forms Reviewed each section of the document One final review for the document. Inspection Meeting Form Issue Logging Form Inspection Moderator Form

INSPECTION - CODE Team 5 Informal Review  Desk check of a software engineering  Verify that the software meets its requirements Pair Programming  Uncover errors in function, logic, and implementation

TESTING Team 5 ADIL KHAN

TESTING Team 5 White Box Testing Black Box Testing

TESTING Team 5 White Box Testing Tested SmilTransporter library with google chat client. Tested CloudDataProvider with local GAE server and then with actual Cloud with billing enabled. (inconsistencies found). Tested Composer/Player functionality, in playing various components on emulator/real device. (Inconsistencies on emulator found). Tested SMILMedia ArrayList Structures, passed to and from CommunicationProvider.

TESTING Team 5 Black Box Testing Tested Interface between Composer and Communication Provider. Upload of files Passing of SMIL Messages. Tested interface between Player and Communication Provider. Download of Files Receiving of SMIL Message.

TESTING Team 5 Black Box Testing (Continued) Tested consistency of SMIL message passed from Composer to Player. Play SMIL on composer and compare to Playing on player.
