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.

Base DataSource implementation to keep a list of TransferListeners.
Subclasses must call transferInitializing(DataSpec), transferStarted(DataSpec), bytesTransferred(int), and transferEnded() to inform listeners of data transfers.

    Specified by:
    
    addTransferListener in interface DataSource
    
    Parameters:
    
    transferListener - A TransferListener.
  - transferInitializing
```
protected final void transferInitializing(DataSpec dataSpec)
```
    Deprecated.
    
    Notifies listeners that data transfer for the specified DataSpec is being initialized.
    
    Parameters:
    
    dataSpec - DataSpec describing the data for initializing transfer.
  - transferStarted
```
protected final void transferStarted(DataSpec dataSpec)
```
    Deprecated.
    
    Notifies listeners that data transfer for the specified DataSpec started.
    
    Parameters:
    
    dataSpec - DataSpec describing the data being transferred.
  - bytesTransferred
```
protected final void bytesTransferred(int bytesTransferred)
```
    Deprecated.
    
    Notifies listeners that bytes were transferred.
    
    Parameters:
    
    bytesTransferred - The number of bytes transferred since the previous call to this method (or if the first call, since the transfer was started).
  - transferEnded
```
protected final void transferEnded()
```
