My streaming audio player continues to play during

Question

I have an app that consists of multiple activities and one service. The primary activity is a UI for streaming audio. When the user pushes the play button, the service is started, streaming the audio and reading metadata. The metadata is then pushed to the UI if visible and the Notification Bar. Everything functions as expected until a phone call comes in. I had assumed (silly me) that by using the standard media player, android would handle switching audio between the stream and phone call itself. So I created a PhoneStateListener to handle the calls and stop my player as needed. I've done something wrong though, because it still isn't working. If you wouldn't mind looking at the service class and perhaps the log files, I'd really appreciate it!

Sorry everything is so verbose!

Thank you! Dae
