| ↳ | android.media.MediaActionSound |
A class for producing sounds that match those produced by various actions taken by the media and camera APIs.
Use this class to play an appropriate camera operation sound when implementing a custom still or video recording mechanism (through the Camera preview callbacks with Camera.setPreviewCallback, or through GPU processing with Camera.setPreviewTexture, for example), or when implementing some other camera-like function in your application.
There is no need to play sounds when using Camera.takePicture or MediaRecorder for still images or video, respectively, as the Android framework will play the appropriate sounds when needed for these calls.

A sound to indicate that focusing has completed. Because deciding when this occurs is application-dependent, this sound is not used by any methods in the media or camera APIs.
The sound used by Camera.takePicture to indicate still image capture.
The sound used by MediaRecorder.start() to indicate the start of video recording.
The sound used by MediaRecorder.stop() to indicate the end of video recording.
Construct a new MediaActionSound instance. Only a single instance is needed for playing any platform media action sound; you do not need a separate instance for each sound type.
Preload a predefined platform sound to minimize latency when the sound is played later by play(int).
| soundName | The type of sound to preload, selected from SHUTTER_CLICK, FOCUS_COMPLETE, START_VIDEO_RECORDING, or STOP_VIDEO_RECORDING. |

Play one of the predefined platform sounds for media actions.
Use this method to play a platform-specific sound for various media actions. The sound playback is done asynchronously, with the same behavior and content as the sounds played by Camera.takePicture, MediaRecorder.start, and MediaRecorder.stop.
Using this method makes it easy to match the default device sounds when recording or capturing data through the preview callbacks, or when implementing custom camera-like features in your application.
If the sound has not been loaded by load(int) before calling play, play will load the sound at the cost of some additional latency before sound playback begins.
| soundName | The type of sound to play, selected from SHUTTER_CLICK, FOCUS_COMPLETE, START_VIDEO_RECORDING, or STOP_VIDEO_RECORDING. |
