How can I import a file into my Windows Phone 8.1RT App?

Question

Hi All,
I'm running into a bit of an issue associating my app with a custom file type.  Users create a file using my app and upload it to their OneDrive for sharing.  So I then want to give the users the ability to download the file from a share link and
have that file open automatically in my app.  I've got the appropriate declarations set and file type associations, but I'm getting a file access exception when I try to open the file.  Whats the best way to import a file into my app?  Here's
the code I've got so far:
protected override async void OnFileActivated(FileActivatedEventArgs args)
var path = args.Files[0].Path;
var name = args.Files[0].Name;
StorageFile newFile = await StorageFile.GetFileFromPathAsync(path);
await newFile.CopyAsync(ApplicationData.Current.LocalFolder, name.Substring(0, name.Length - 4));
The path comes back as
C:\Data\Users\DefApps\APPDATA\Local\Packages\microsoft.microsoftskydrive_8weke\LocalState\OpenWithTempFolder\e68c261-db3b-472d-a8b7-93427450\File Name.extension
and the exception is
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
Clearly I'm trying to access the file in an inappropriate way, so what's the best way to get the file into my app's local storage?

Answer 1

You have the StorageFile in arg.Files[0] already. Just use that rather than getting its path and then trying to create a new StorageFile from it.
var path = args.Files[0].Path; // <= Path is unnecessary and unhelpful
var name = args.Files[0].Name;
await args.Files[0].CopyAsync(ApplicationData.Current.LocalFolder, name.Substring(0, name.Length - 4));
See my blog entry Skip the path: stick to the StorageFile for more details.
