Xamarin.DropBox.APi - HTTP 400 (Bad request) on DownloadAsync
Hi, I have the following code in a static helper class which works perfectly in a Windows UWP app: public static DropboxClient dbxClient { get; private set; } ...... public static async Task<stri...
The Dropbox API does require one of a certain set of Content-Type values for download calls like this. The official Dropbox.Api library (i.e., the official Dropbox API v2 .NET SDK) does automatically set a valid Content-Type, so you don't need to do that yourself when using it.
It sounds like when you switch to Xamarin and the Xamarin.Dropbox.Api library, something is overriding it and setting an incorrect Content-Type. I'm afraid we can't offer help with those though, as they're made/maintained by a third party. You may be better served contacting the Xamarin maintainers or asking on a Xamarin forum.

Thanks Greg - I thought the Xamarin DropBox APi was a variant on the official but as it's not I'll ask over on the Xamarin forums.
Hello,
I have the same problem. did you solve it?.
thanks
No, I still have not fixed this but I have not really been looking at it due to other projects. However, I am now back trying to work out why I get his error - but so far no luck.
If I find out i will post here - but if you have solved the problem could you please post your answer here?
Hi Guys,
I too was stuck at this problem, as i wanted a free data storage and retreval for my Xamarin.forms App.
Here are some of the points that i understood with this problem:
1. Xamarin is not yet supported by DropBox yet.
2. The above problem is in the autosetting done by xamarin frame work at the backend.
Ans:
Right click on android project of your solution > Select Properties
Goto Android Options> Select Advance Properties
- Select HttpClient implementation as Default ( this would be by default set to Android).
and Select SSL/TLS implementation as Native TLS 1.2+.
Now compile and run your Xamarin.Forms application, it should work like a charm.
