class DownloadManager
```
*** ** * ** ***
Manages downloads.
Normally a download manager should be accessed via a[DownloadService](https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/offline/DownloadService). When a download manager is used directly instead, downloads will be initially paused and so must be resumed by calling[resumeDownloads](https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/offline/DownloadManager#resumeDownloads()).
A download manager instance must be accessed only from the thread that created it, unless that thread does not have a[Looper](https://developer.android.com/reference/android/os/Looper.html). 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](https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/offline/DownloadManager#getApplicationLooper()).
