Capture stats from volleyball video using my Android app

I have developed an Android app to record statistics for volleyball matches. I am looking for multiple people with Android tablets to install the software and use it to capture statistics from a video I will provide. You will also be provided with a list of players and other admin data that you will be expected to enter into the application. Finally, you will be provided with a document that explains how to recognize when something in one of the various statistical categories occurs. This is a test run, so everyone who participates will be provided with the same video. The match you will be processing is approximately 40 minutes in length. I expect the whole process should take no more than 1.5 hours. The application has an export function that you will use to submit the finished work to me.
