Continuous audio capture

The goal of this app is to continuously record audio with minimal interruption. Once activated by the user, the app should start a background service which continuously records all audio from the microphone. The service should persist even after the main app interface is closed, and should automatically start after a reboot or crash. The recording should only stop recording when the user specifically turns it off. Critical: Do not interfere with any other functionality of the device, including phone calls, Skype calls, etc. Required features: - A switch to activate/deactivate the recording service - A persistent service which outlives the main app activity, launches automatically at boot if active, etc. - Store the audio in small files with timestamp metadata (recordings should be broken up into smaller files if above a certain size) - Configurable audio quality (configurable in source code is good enough) Nice to have: - A switch to enable/disable recording audio during phone calls (available in the main app settings, not as a button during a phone call) - Automatic upload to a web service over wifi (we can discuss the implementation of this) Not necessary: - Playback of audio in the app (this may be implemented in the future)
