public interface BitmapLoader

Known direct subclasses

BitmapLoader, CacheBitmapLoader, DataSourceBitmapLoader, SimpleBitmapLoader, SizeLimitedBitmapLoader

`BitmapLoader`	This interface is deprecated. Use `androidx.media3.common.util.BitmapLoader` instead.
`CacheBitmapLoader`	A `BitmapLoader` that caches the result of the last `decodeBitmap`, `loadBitmap` or `loadBitmapFromMetadata` request.
`DataSourceBitmapLoader`	A `BitmapLoader` implementation that uses a `DataSource` to support fetching images from URIs and `BitmapFactory` to load them into `Bitmap`.
`SimpleBitmapLoader`	This class is deprecated. Use `androidx.media3.datasource.DataSourceBitmapLoader` instead.
`SizeLimitedBitmapLoader`	A `BitmapLoader` that limits the size of bitmaps loaded by `decodeBitmap` or `loadBitmap` request.

Loads images.

Summary

Public methods
`abstract ListenableFuture<Bitmap>`	`decodeBitmap(byte[] data)` Decodes an image from compressed binary data.
`abstract ListenableFuture<Bitmap>`	`loadBitmap(Uri uri)` Loads an image from `uri`.
`default @Nullable ListenableFuture<Bitmap>`	`loadBitmapFromMetadata(MediaMetadata metadata)` Loads an image from `MediaMetadata`.
`abstract boolean`	`supportsMimeType(String mimeType)` Returns whether the given `mimeType` is supported.

Public methods

decodeBitmap

abstract ListenableFuture<Bitmap> decodeBitmap(byte[] data)

Decodes an image from compressed binary data.

loadBitmap

abstract ListenableFuture<Bitmap> loadBitmap(Uri uri)

Loads an image from uri.

loadBitmapFromMetadata

default @Nullable ListenableFuture<Bitmap> loadBitmapFromMetadata(MediaMetadata metadata)

Loads an image from MediaMetadata. Returns null if metadata doesn't contain bitmap information.

By default, the method will try to decode an image from artworkData if it is present. Otherwise, the method will try to load an image from artworkUri if it is present. The method will return null if neither artworkData nor artworkUri is present.

supportsMimeType

abstract boolean supportsMimeType(String mimeType)

Returns whether the given mimeType is supported.
