Deprecated.
com.google.android.exoplayer2 is deprecated. Please migrate to androidx.media3 (which contains the same ExoPlayer code). See the migration guide for more details, including a script to help with the migration.

Interface for loaders of ads, which can be used with AdsMediaSource.
Ads loaders notify the AdsMediaSource about events via AdsLoader.EventListener. In particular, implementations must call AdsLoader.EventListener.onAdPlaybackState(AdPlaybackState) with a new copy of the current AdPlaybackState whenever further information about ads becomes known (for example, when an ad media URI is available, or an ad has played to the end).
start(AdsMediaSource, DataSpec, Object, AdViewProvider, EventListener) will be called when an ads media source first initializes, at which point the loader can request ads. If the player enters the background, stop(AdsMediaSource, EventListener) will be called. Loaders should maintain any ad playback state in preparation for a later call to start(AdsMediaSource, DataSpec, Object, AdViewProvider, EventListener). If an ad is playing when the player is detached, update the ad playback state with the current playback position using AdPlaybackState.withAdResumePositionUs(long).
If AdsLoader.EventListener.onAdPlaybackState(AdPlaybackState) has been called, the implementation of start(AdsMediaSource, DataSpec, Object, AdViewProvider, EventListener) should invoke the same listener to provide the existing playback state to the new player.

  - setPlayer
```
void setPlayer(@Nullable
               Player player)
```
    Deprecated.
    
    Sets the player that will play the loaded ads.
    This method must be called before the player is prepared with media using this ads loader.
    This method must also be called on the main thread and only players which are accessed on the main thread are supported (player.getApplicationLooper() == Looper.getMainLooper()).
    
    Parameters:
    
    player - The player instance that will play the loaded ads. May be null to delete the reference to a previously set player.
  - release
```
void release()
```
    Deprecated.
    
    Releases the loader. Must be called by the application on the main thread when the instance is no longer needed.
  - setSupportedContentTypes
```
void setSupportedContentTypes(@ContentType
                              @com.google.android.exoplayer2.C.ContentType int... contentTypes)
```
    Deprecated.
    
    Sets the supported content types for ad media. Must be called before the first call to start(AdsMediaSource, DataSpec, Object, AdViewProvider, EventListener). Subsequent calls may be ignored. Called on the main thread by AdsMediaSource.
    
    Parameters:
    
    contentTypes - The supported content types for ad media. Each element must be one of C.CONTENT_TYPE_DASH, C.CONTENT_TYPE_HLS, C.CONTENT_TYPE_SS and C.CONTENT_TYPE_OTHER.

           AdsLoader.EventListener eventListener)
```
    Deprecated.
    
    Starts using the ads loader for playback. Called on the main thread by AdsMediaSource.
    
    Parameters:
    
    adsMediaSource - The ads media source requesting to start loading ads.
    
    adTagDataSpec - A data spec for the ad tag to load.
    
    adsId - An opaque identifier for the ad playback state across start/stop calls.
    
    adViewProvider - Provider of views for the ad UI.
    
    eventListener - Listener for ads loader events.
  - stop
```
void stop(AdsMediaSource adsMediaSource,
          AdsLoader.EventListener eventListener)
```
    Deprecated.
    
    Stops using the ads loader for playback and deregisters the event listener. Called on the main thread by AdsMediaSource.
    
    Parameters:
    
    adsMediaSource - The ads media source requesting to stop loading/playing ads.
    
    eventListener - The ads media source's listener for ads loader events.
  - handlePrepareComplete
```
void handlePrepareComplete(AdsMediaSource adsMediaSource,
                           int adGroupIndex,
                           int adIndexInAdGroup)
```
    Deprecated.
    
    Notifies the ads loader that preparation of an ad media period is complete. Called on the main thread by AdsMediaSource.
    
    Parameters:
    
    adsMediaSource - The ads media source for which preparation of ad media completed.
    
    adGroupIndex - The index of the ad group.
    
    adIndexInAdGroup - The index of the ad in the ad group.
  - handlePrepareError

```
    Deprecated.
    
    Notifies the ads loader that the player was not able to prepare media for a given ad. Implementations should update the ad playback state as the specified ad has failed to load. Called on the main thread by AdsMediaSource.
    
    Parameters:
    
    adsMediaSource - The ads media source for which preparation of ad media failed.
