    I need a small update to my Android app to fix a webview so that it will play HTML5 (mainly YouTube videos). I also need a small change in one of the input forms from a single line to a multi-line input. The full source of my existing app will be provided.Finally, I need some help via TeamViewer to set up this project in my own system (with source gontrol GitHub or similar) and to show me how to make minor edits to the sources code in the Android Development Environment. I am familiar with this in iOS and Windows Phone but have no experience with Android and need some help getting setup. This is a very small project - not more than a few hours work - but if all goes well, there can be larger jobs in the future. I am looking for a developer who can help with larger projects in the future. Thank you for your interest.
