下载管理器请求 setNotificationVisiblity

Question

参考：https://developer.android.com/reference/android/app/DownloadManager.Request

setNotificationVisibility(int visiblity)

Control whether a system notification is posted by the download manager while this download is running or when it is completed. If enabled, the download manager posts notifications about downloads through the system NotificationManager. By default, a notification is shown only when the download is in progress.

It can take the following values: VISIBILITY_HIDDEN, VISIBILITY_VISIBLE, VISIBILITY_VISIBLE_NOTIFY_COMPLETED.

If set to VISIBILITY_HIDDEN, this requires the permission android.permission.DOWNLOAD_WITHOUT_NOTIFICATION.

所以我想setNotificationVisiblity到VISIBLITY_HIDDEN。根据 docs 我需要在 AndroidManifest.xml 中设置权限。权限在哪里？

我在 Manifest.permission

中找不到权限 android.permission.DOWNLOAD_WITHOUT_NOTIFICATION

参考：https://developer.android.com/reference/android/Manifest.permission

此权限是否已从 Android 中删除？如果我未经许可设置 downaloadReq.setNotificationVisibility(DownloadManager.Request.VISIBILITY_HIDDEN)，它会抛出一个 SecurityException。那我该怎么办？

Answer 1

AndroidManifest.xml 文件中确实缺少您的许可。

只需添加以下行：

<uses-permission android:name="android.permission.DOWNLOAD_WITHOUT_NOTIFICATION"/>
