Word 文档在使用 Intent 打开时始终为只读

问题描述

我正在尝试使用 MS-Word 在我的 Xamarin.Android 应用程序中打开和编辑位于外部存储中的 word 文档这段代码:

I am trying to open and edit a word document located in my external storage in my Xamarin.Android App with MS-Word with this code:

File wordFile = new File(wordFilePath);
wordFile.SetWritable(true);

FileInfo fileInfo = new FileInfo(wordFilePath);
fileInfo.IsReadOnly = false;

Android.Net.Uri uri = FileProvider.GetUriForFile(Context, Context.PackageName + ".provider", wordFile);

Intent intent = new Intent();
intent.AddFlags(ActivityFlags.NewTask);
intent.AddFlags(ActivityFlags.GrantReadUriPermission);
intent.AddFlags(ActivityFlags.GrantWriteUriPermission);
intent.AddFlags(ActivityFlags.GrantPersistableUriPermission);
intent.SetAction(Intent.ActionView);

intent.SetData(uri);

Context.StartActivity(intent);

问题是，该文件总是只读.当我通过任何文件浏览器(例如 File Manager Pro)打开文档时，它非只读，我可以编辑该文件.

The problem is, that the file is always Read-Only. When I open the document via any file explorer (e.g. File Manager Pro) , it is not Read-Only and I can edit the file.

我是否缺少需要在我的应用或 FileProvider 中设置的任何权限?

Am I missing any permission that i need to set in my app or FileProvider?

intent.SetAction(Intent.ActionView);
intent.SetDataAndType(uri, "application/vnd.openxmlformats-officedocument.wordprocessingml.document");

intent.AddFlags(ActivityFlags.GrantPersistableUriPermission);
