<div class="block">A helper for initializing and removing downloads.
|
|
|

<p>The helper extracts track information from the media, selects tracks for downloading, and

creates <a href="DownloadRequest.html" title="class in com.google.android.exoplayer2.offline"><code>download requests</code></a> based on the selected tracks.
|
|
|
|
<p>A typical usage of DownloadHelper follows these steps:
|
|
|
|
<ol>
|
|
<li>Build the helper using one of the <code>forMediaItem</code> methods.
|
|
<li>Prepare the helper using <a href="#prepare(com.google.android.exoplayer2.offline.DownloadHelper.Callback)"><code>prepare(Callback)</code></a> and wait for the callback.
|
|
<li>Optional: Inspect the selected tracks using <a href="#getMappedTrackInfo(int)"><code>getMappedTrackInfo(int)</code></a> and <a href="#getTrackSelections(int,int)"><code>getTrackSelections(int, int)</code></a>, and make adjustments using <a href="#clearTrackSelections(int)"><code>clearTrackSelections(int)</code></a>, <a href="#replaceTrackSelections(int,com.google.android.exoplayer2.trackselection.DefaultTrackSelector.Parameters)"><code>replaceTrackSelections(int, Parameters)</code></a> and <a href="#addTrackSelection(int,com.google.android.exoplayer2.trackselection.DefaultTrackSelector.Parameters)"><code>addTrackSelection(int, Parameters)</code></a>.
|
|
<li>Create a download request for the selected track using <a href="#getDownloadRequest(byte%5B%5D)"><code>getDownloadRequest(byte[])</code></a>.
|
|
<li>Release the helper using <a href="#release()"><code>release()</code></a>.
