Android App POSIT – September Code Sprint in Toronto

A firsthand account from the UCOSP Code sprint in Totonto on XX. by POSIT project team members :

UCOSP (Undergraduate Capstone Open Source Projects) gives students all across Canada the opportunity to work together and collaborate on joint open source projects. One of the great projects of UCOSP is POSIT, an android application from the Humanitarian FOSS project.

Since many of the students in UCOSP are from different regions of Canada, the wonderful steering committee of UCOSP organized a 3-day code sprint, held in Toronto, for students to meet face to face and familiarize themselves with the projects together. Members of the POSIT project, Gordon, Stanley, Ryan, Kalin, and Eric were all extremely excited to attend the code sprint; some even traveled from Vancouver and Edmonton to Toronto.

On the first day of code sprint, we devised a tentative plan for the next three days, based on our supervisor Professor Ralph Morelli’s agenda. Since working on POSIT was our first time working in an Android development environment, we decided to set up the Java Android environment and work through Google’s online tutorials to  really understand the structure and workflow of an Android application. We have found that the Notepad Tutorial (http://developer.android.com/resources/tutorials/notepad/index.html) was particularly helpful because not only did it show us the standard Android framework, it also introduced the Java SQL database, which was essential in understanding the inner-working of the POSIT application.

One of the biggest challenges of working with team members all around Canada is effective team communication and efficient project coordination. We were thus grateful that, during the second day of the code sprint, our supervisor Ralph showed us many tools that we could utilize to easily collaborate and share with the team online. Such tools include online POSIT wiki and ticketing system where we can report and resolve issues encountered in using POSIT; and Mercurial for managing POSIT’s online code repository. With the help of Ralph, we also successfully deployed the demo POSIT application on our phone to test out its basic features.

Ralph also mentioned that he and POSIT’s past development team decided to overhaul POSIT’s overall framework to make it a more agile and configurable application. He introduced us the concept of “plug-in”, with one “plug-in” being its own separate application that has different user interface and supports one or more data types (texts, images, videos, etc). He also shared with us his vision on how users could simply configure the “plug-in” online and our code base would auto-magically generate a brand new version of POSIT with the specifications defined in “plug-in”.

We were all very excited with the idea of configurable application, but in order to get there, we needed to first understand the structure of the existing POSIT code base. On the last day of code sprint, Ralph pointed us to some fundamental POSIT framework and we each read through a part of the POSIT code base. Before we all left for our lovely home city, we had set up the date for our weekly Skype meeting so that we could update each other on our progress and coordinate project features.

Throughout the three days of code sprint, we all felt like we had accomplished a lot. We were so glad to meet each other face to face and were given the opportunity to work on such a great project. We really look forward to collaborating with each other and we cannot wait to see what our final POSIT application will be like.
