During the last few weeks I developed an Android application for helping people prepare for the Israeli driving theory test. The application uses the questions database available from http://data.gov.il/dataset/249 (and the corresponding ones for Russian and Arabic). It was a nice and fun exercise, which helped me master more parts of the Android development platform.
The application is now at version 0.1 and is working. Its look and feel is not polished, yet; and some missing features have been identified by comparing it to three other applications available from Google Play doing the same thing.
Today the source code has been released under the GPLv3 and is available from https://github.com/tddpirate/teuria and if you are looking for an Android developer with few weeks worth of experience and known quality of work, you may have a look at the above.
