MediaBrowserExtras

Kotlin |Java

class MediaBrowserExtras

Defines constants for extra keys in androidx.media.MediaBrowserServiceCompat.

Media apps can use these extras to enhance their analytics.

They can also take them into account to decide how many media items to return. For example, providing a number of recommendation items that is a multiple of the maximum number of items shown in a grid row will use the screen space more efficiently (avoiding blanks).
