Artifact: [androidx.media3:media3-datasource](https://developer.android.com/jetpack/androidx/releases/media3) [View Source](https://cs.android.com/search?q=file:androidx/media3/datasource/DataSourceBitmapLoader.java+class:androidx.media3.datasource.DataSourceBitmapLoader)

```
@UnstableApi
public final class DataSourceBitmapLoader implements BitmapLoader
```

<br />

*** ** * ** ***

A `https://developer.android.com/reference/androidx/media3/common/util/BitmapLoader` implementation that uses a `https://developer.android.com/reference/androidx/media3/datasource/DataSource` to support fetching images from URIs and `https://developer.android.com/reference/android/graphics/BitmapFactory.html` to load them into `https://developer.android.com/reference/android/graphics/Bitmap.html`.

Loading tasks are delegated to a `https://guava.dev/releases/snapshot-android/api/docs/com/google/common/util/concurrent/ListeningExecutorService.html` defined during construction. If no executor service is passed, all tasks are delegated to a single-thread executor service that is shared between instances of this class.
