I'm building an android app with Xamarin which communicates with an ASP.net server's API. I'm trying to upload a file to the server using the following lines of code:
public async Task<HttpResponseMessage> UploadFile(byte[] file)
{
var progress = new System.Net.Http.Handlers.ProgressMessageHandler();
//progress.HttpSendProgress += progress_HttpSendProgress;
using (var client = HttpClientFactory.Create(progress))
{
client.BaseAddress = new Uri(GlobalVariables.host);
// Set the Accept header for BSON.
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/bson"));
var request = new uploadFileModel { data = file, dateCreated = DateTime.Now, fileName = "myvideooo.mp4", username = "psyoptica" };
// POST using the BSON formatter.
MediaTypeFormatter bsonFormatter = new BsonMediaTypeFormatter();
var m = client.MaxResponseContentBufferSize;
var result = await client.PostAsync("api/media/upload", request, bsonFormatter);
return result.EnsureSuccessStatusCode();
}
}
The app crashes before the server receives the request. The file I'm trying to upload could be a video or an audio file. The server receives the request after the app has crashed. This works fine on the local server but the crash happens with the live server. My server side code looks like this:
[HttpPost]
[Route("upload")]
public async Task<HttpResponseMessage> Upload(uploadFileModel model)
{
var result = new HttpResponseMessage(HttpStatusCode.OK);

What am I doing wrong here that's making the app crash. Is there a better way to do this?
Any help is appreciated.

You need to add event handlers to the combo for either SelectedIndexChangedEvent (if it's a non-editable combo), or TextUpdateEvent if it is (likely both in that latter case). Those event handlers then change the other controls as needed.
I'm trying to work with the UPS api to create a shipping label. The UPS api uses a webservice to send an XML request to UPS. UPS then sends a response back. Here is my question.
Is there a way to view the XML that is outputted when I call the "shipmentRequest" method?
This is the first time I've used an API and a webservice so if you need me to provide more information just let me know.
Thanks!

You can inherit from the UPS service and read the response as xml by providing your own XmlWriter by overriding GetWriterForMessage(). You can see a working example here.
i am using this code display xml it may help you.
XDocument mySourceDoc = new XDocument();
mySourceDoc = XDocument.Load(shipmentResponse);
txtxml.Text = mySourceDoc.ToString();
