Android SMIL Messenger Presented By: Alex Povkov Brad Gardner Jeremy Spitzig Santiago Jamriska

Introduction This application uses the Android 1.6 Platform and later and will provide a multimedia messaging system for users to communicate with each other, sharing pictures, videos, audio, and text-based content using messages created based on the SMIL specification.

How does it work? Users can create or view messages Multiple media types can be added to a message You can preview, save or send any message

Use Cases We have three Actors: the Sender, the Receiver and the Server Both the Sender and the Receiver have the same main interaction with the application The server is the mediator

Implementation (GUI) Main Menu: Users can choose to create a new message or view stored messages

Implementation (GUI) Messages: In here, the user can view received messages, sent messages, and saved unsent messages.

Implementation (GUI) New Message: In here, users can define the layout of the message After defining the layout, users can go on to creating the contents of the message

Add Components: Users can choose what type of components to add to the message Text Images Audio Files Video Files Implementation (GUI)

Settings: Users can insert text, files, duration time, and a start time to the specific components

Player: Users can preview the messages before sending them, and view the messages as they are received Implementation (GUI)

HTTP Sockets: Using sockets, the devices are able to communicate to a central server where they can download the message details. SMS Messaging: SMS (Short Message Service) will be used to notify devices that they have a new message in the central server. Implementation (Communications)

Team Communication Gmail-based Communications

Team Communication Google code and Wiki-based Communications

All media worked perfectly on the emulator Communications with the server and the other emulated device worked perfectly as well Decided to deploy under Android 1.6 Android 1.6 Testing

Mounted application onto Android-based phone (Running Android 1.6) Application worked perfectly on a single phone. Had a few issues in communications when using a second phone. Issues were resolved by tweaking the code and the server Device Testing

Testing Testing Models: 1.Android 2.1 Testing 2.Android 1.6 Testing 3.Device Testing

Android 2.1 Testing We emulated Android 2.1 for the first tests of the application Emulation of the video playback didn’t work Dropped emulator to version 1.6

Testing Junit:

Summary We have successfully completed the requirements for this project. A fully functional Android SMIL Messenger application has been achieved according to both the Android and SMIL component specifications. The course objectives were also followed and successfully completed throughout the semester.
