Xamarin.OneDrive.Connector

A wrapper around microsoft identity connector and microsoft graph api to access one drive content

Sample of how to use the library

Simplest get-started sample

   using Xamarin.OneDrive;

   var connector = new Connector("YOUR_MICROSOFT_APPLICATION_ID", "User.Read");
   if (await connector.ConnectAsync())
   {
      var httpMessage = await connector.GetAsync("me");
      /* json message with the requested data */
   }
   connector.Dispose();

Using the profile plugin to request user profile data

   using Xamarin.OneDrive;
   using Xamarin.OneDrive.Profile;

   var connector = new Connector("YOUR_MICROSOFT_APPLICATION_ID", "User.Read");
   if (await connector.ConnectAsync())
   {
      var profile = await connector.GetProfileAsync();
      Console.WriteLine($"Connected to {profile.Name} account through address {profile.Mail}");
   }
   connector.Dispose();

Using the files plugin to search download and manipulate files stored in OneDrive

   using Xamarin.OneDrive;
   using Xamarin.OneDrive.Files;

   var connector = new Connector("YOUR_MICROSOFT_APPLICATION_ID", "Files.Read");
   if (await connector.ConnectAsync())
   {
      var fileList = await connector.SearchFilesAsync("*.zip");
      Console.WriteLine($"Retrieved {fileList.Count} files on the search request");
      var file = fileList[0];
      Console.WriteLine($"The file {file.FileName} has {file.Bytes} bytes and is located on {file.FilePath}.");
   }
   connector.Dispose();

Android project required MainActivity overrides

protected override void OnCreate(Bundle savedInstanceState)
{
   ...
   Xamarin.Forms.Forms.Init(this, savedInstanceState);
   Xamarin.OneDrive.Connector.Init(this); /* optionally we could pass a specific redirectUrl */
   ...
}
protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
   base.OnActivityResult(requestCode, resultCode, data);
   Xamarin.OneDrive.Connector.SetAuthenticationContinuationEventArgs(requestCode, resultCode, data);
}
