updated to adapter view

adapter view displays only, doesn't handle clicks yet
updated member variables to android style guidelines
better network error handling, more logging
cherry pick, play sends intent

play button sends intent with action and url

the hope is that when the service is closed for memory, and resumes later, the intent to play the url will be redelivered
