如何获取MANAGE_EXTERNAL_STORAGE权限

Question

我正在尝试在我的Android10(API29)设备上获得MANAGE_EXTERNAL_STORAGE权限。

https://developer.android.com/training/data-storage/manage-all-files

清单：

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

主要活动：

Intent intent = new Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION);
startActivity(intent);

No Activity found to handle Intent { act=android.settings.MANAGE_APP_ALL_FILES_ACCESS_PERMISSION }

In some cases, a matching Activity may not exist, so ensure you safeguard against this.

但我怎样才能得到那个许可呢？

Android10不需要“Android.permission.manage_external_storage”，清单中应用程序标记下的Android:requestlegacyexternalstorage=“true”可以工作。

对于Android11，试试这个

if (Environment.isExternalStorageManager()) {
    //todo when permission is granted
} else {
    //request for the permission
    Intent intent = new Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION);
    Uri uri = Uri.fromParts("package", getPackageName(), null);
    intent.setData(uri);
    startActivity(intent);
}
