Error in call to API function "files/download"
I use DropBox API to implement Dropbox in Xamarin.Forms (NET Standard). I upload a file success, but when I download I get this error
Dropbox.Api.BadInputException: Error in call to API function "files/download": Bad HTTP "Content-Type" header: "application/x-www-form-urlencoded". Expecting one of "text/plain", "text/plain; charset=utf-8", "application/octet-stream", "application/octet-stream; charset=utf-8".
using (var client = new DropboxClient(this.AccessToken)) { using (var response = await client.Files.DownloadAsync(file.FilePath + "/" + file)) { var pickedFile = await response.GetContentAsByteArrayAsync(); //FileImagePreview.Source = ImageSource.FromStream(() => pickedFile); } }
this answer solved my problem.

Thanks!
In addition, I think the problem originates from Xamarin using the "AndroidClientHandler" as HttpMessageHandler. So using the current lib version, a workaround would be explicitly setting the (less efficient) HttpClientHandler
dbx = new DropboxClient(accessToken, new DropboxClientConfig() { HttpClient = new HttpClient(new HttpClientHandler()) });
I am facing error when downloading shared file using DropBox API. getting 503.

nguyenthanhliem The Dropbox .NET SDK isn't officially supported on Xamarin, but there was another thread where a developer ran into this issue and was reportedly able to resolve it here:
I have look in your link and I think they still not found solution for this!

I'm afraid I can't offer more information though, as the Dropbox .NET SDK isn't officially supported on Xamarin. Apologies I can't be of more help in that regard!
