Executive Summary

For my final project I would like to develop and compile Java code on the BeagleBoard to create an application for Twitter that allows a user to sign in from the Beagle and post tweets using the Java Twitter API called Twitter4J.

Currently I have a graphical interface built using the Java Swing library. The user can log in to his or her twitter account using twitters external authentication and then will be able to see their profile picture, screen name, and current status. This status can be updated as well as users can be searched for to have their profile pictures and status displayed below.


Installation Instructions

Install the Java Development Kit on the beagle opkg install openjdk-6-jdk

Download the Twitter4j Library from: http://twitter4j.org/en/index.html

Extract the zip file into a directory of your choice

Git Location:

https://github.com/Zitnikdj/BeagleTweet

User Instructions

I compile and run my code on the beagle using the Open JDK6 and using the commands assuming the file Main.java has my main method in it:

Compiling .java files in directory

javac -cp <directory where you saved the twitter4j library>/twitter4j-2.2.5/lib/twitter4j-core-2.2.5.jar <filename>.java

Or compiling all .java files at once

javac -cp <directory where you saved the twitter4j library>/twitter4j-2.2.5/lib/twitter4j-core-2.2.5.jar *.java

Running the application

java -cp <directory where you saved the twitter4j library>/twitter4j-2.2.5/lib/twitter4j-core-2.2.5.jar Main

Highlights

Theory of Operation

Give a high level overview of the structure of your software. Are you using GStreamer? Show a diagram of the pipeline. Are you running multiple tasks? Show what they do and how they interact.

Work Breakdown

Developed Graphical Interface using Java Swing library

Learned how to compile Java code on the command line on the BeagleBoard

Learned how to do basic interfacing with the Twitter Java API (Twitter4j)

Conclusions

Give some concluding thoughts about the project. Suggest some future additions that could make it even more interesting.
