<!-- Allows an application to read from external storage.
<p>Any app that declares the {@link #WRITE_EXTERNAL_STORAGE} permission is implicitly
granted this permission.</p>
<p class="note"><strong>Note: </strong>Starting in API level 33, this permission has no
effect. If your app accesses other apps' media files, request one or more of these permissions
instead: <a href="#READ_MEDIA_IMAGES"><code>READ_MEDIA_IMAGES</code></a>,
<a href="#READ_MEDIA_VIDEO"><code>READ_MEDIA_VIDEO</code></a>,
<a href="#READ_MEDIA_AUDIO"><code>READ_MEDIA_AUDIO</code></a>. Learn more about the
<a href="{@docRoot}training/data-storage/shared/media#storage-permission">storage
permissions</a> that are associated with media files.</p>
<p>This permission is enforced starting in API level 19. Before API level 19, this
permission is not enforced and all apps still have access to read from external storage.
You can test your app with the permission enforced by enabling <em>Protect USB
storage</em> under Developer options in the Settings app on a device running Android 4.1 or

<p>Starting in API level 29, apps don't need to request this permission to access files in
their app-specific directory on external storage, or their own files in the
<a href="{@docRoot}reference/android/provider/MediaStore"><code>MediaStore</code></a>. Apps
shouldn't request this permission unless they need to access other apps' files in the

developer documentation.</p>

full form until the installer on record allowlists the permission.
