Android 13中的存储权限 - Flutter Android 13

Question

我正在开发一个Flutter应用程序，需要在Android设备上访问存储。该应用程序在Android 12及以下版本上正常运行，但在Android 13设备上遇到了存储权限问题。我已经按照标准的实现方式请求了存储权限，并在应用程序的AndroidManifest.xml文件中包含了必要的权限声明。然而，在Android 13设备上，该应用程序无法访问外部存储并遇到了权限错误。

错误：

我按照标准的实现方式来请求存储权限。但是有一个错误，因为在Android 13中所需的权限已经发生了变化。清单文件中缺少读取媒体文件的权限。 - undefined

我在你的错误日志中没有看到任何与存储或权限有关的内容。 - undefined

Answer 1

根据Android文档，从API级别33开始，READ_EXTERNAL_STORAGE权限不再起作用。对于API级别33及以上，您可以根据您的使用情况使用READ_MEDIA_IMAGES、READ_MEDIA_VIDEO、READ_MEDIA_AUDIO权限。

您可以修改AndroidManifest.xml文件，根据API级别请求相关权限。

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" 
android:maxSdkVersion="32" />

<uses-permission android:name="android.permission.READ_MEDIA_IMAGES"/>
<uses-permission android:name="android.permission.READ_MEDIA_VIDEO"/>
<uses-permission android:name="android.permission.READ_MEDIA_AUDIO"/>

Answer 2

我遇到了完全相同的问题。我的经验是，同样的清单曾用于请求访问文件的权限，现在却要求访问媒体，如图片所示：

这个问题始于2023年7月的最新安全补丁。
