Working with Audio

Much like video, the Android SDK provides methods for audio playback and recording. Audio files can be resources, local files, or Uri objects to shared or network resources. Audio recording takes place through the built-in microphone on the device, if one is present (typically a requirement for a phone because one speaks into it quite often).

Recording Audio

The MediaRecorder object of the Android SDK provides audio recording functionality. Using it is a matter of following a few simple steps you should now find familiar:

1. Instantiate a new MediaRecorder object.

2. Set the audio source.

3. Set the audio format to record with.

4. Set the file format to store the audio in.

5. Set the file to record to.

6. Prepare the object for recording.
