Android 13 中的存储权限 - Flutter Android 13

Question

我正在开发一个需要 Android 设备上的存储访问权限的 Flutter 应用程序。该应用程序在 Android 12 版本之前可以正常运行，但我在 Android 13 设备上遇到了存储权限问题。我遵循请求存储权限的标准实现，并在应用程序的 AndroidManifest.xml 文件中包含必要的权限声明。但是，在 Android 13 设备上，应用程序无法访问外部存储并遇到权限错误。

根据 Android文档， READ_EXTERNAL_STORAGE从 API 级别 33 开始，权限无效。对于 API 级别 33 及以上，您可以根据您的用例使用READ_MEDIA_IMAGES, READ_MEDIA_VIDEO,权限READ_MEDIA_AUDIO

您可以修改 AndroidManifest.xml 以根据 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"/>
