问题描述
我正在尝试在我的Android 10(API 29)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" />
MainActivity:
Intent intent = new Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION);
startActivity(intent);
结果是:
No Activity found to handle Intent { act=android.settings.MANAGE_APP_ALL_FILES_ACCESS_PERMISSION }
好的,此行为是可能的。医生说:
In some cases,a matching Activity may not exist,so ensure you safeguard against this.
但是我如何获得该许可?
解决方法
Android 10 不需要“android.permission.MANAGE_EXTERNAL_STORAGE”,manifest 中应用程序标签下的 android:requestLegacyExternalStorage="true" 将起作用。
对于 android 11,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);
}
