AudioMetadata.Key
| android.media.AudioMetadata.Key<T>
|
Key interface for the AudioMetadata map.
The presence of this Key interface on an object allows
it to reference metadata in the Audio Framework.
Vendors are allowed to implement this Key interface for their debugging or
private application use. To avoid name conflicts, vendor key names should be qualified by
the vendor company name followed by a dot; for example, "vendorCompany.someVolume".
