  • @Deprecated
public final class DownloadManager
extends Object
    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.
    Manages downloads.

    Normally a download manager should be accessed via a DownloadService. When a download manager is used directly instead, downloads will be initially paused and so must be resumed by calling resumeDownloads().

    A download manager instance must be accessed only from the thread that created it, unless that thread does not have a Looper. In that case, it must be accessed only from the application's main thread. Registered listeners will be called on the same thread. In all cases the `Looper` of the thread from which the manager must be accessed can be queried using getApplicationLooper().

      • DownloadManager

        public DownloadManager​(Context context,
                       DatabaseProvider databaseProvider,
                       Cache cache,
                       DataSource.Factory upstreamFactory,
                       Executor executor)
        Deprecated.
        Constructs a DownloadManager.
        Parameters:
        context - Any context.
        databaseProvider - Provides the SQLite database in which downloads are persisted.
        cache - A cache to be used to store downloaded data. The cache should be configured with an CacheEvictor that will not evict downloaded content, for example NoOpCacheEvictor.
        upstreamFactory - A DataSource.Factory for creating DataSources for downloading data.
        executor - An Executor used to download data. Passing Runnable::run will cause each download task to download data on its own thread. Passing an Executor that uses multiple threads will speed up download tasks that can be split into smaller parts for parallel execution.
