How do I upload a file from an android device to a restful wcf service?

I'm building an Android app and I need to upload a photo taken with the camera. I need to upload it to a restful WCF service. I have looked at many tutorials but I just can't seem to get it working. I think my problem lies with the WCF service. I do not get any exceptions but I get a response 400 BAD REQUEST. Since the WCF service is currently running on my localhost, I am using 10.0.2.2 to access it from the android emulator. I am able to call other service methods on my local service but this one fails.

Java

HttpPost httppost = new HttpPost("http://10.0.2.2:53943/ImageService/UploadInspectionPhoto");
File photo = new File(Environment.getExternalStorageDirectory(), "01.jpg");
MultipartEntity t = new MultipartEntity();
t.addPart("t", new FileBody(photo));
//t.addPart(new FormBodyPart("t", new FileBody(photo))); I tired this too
httppost.setEntity(t);
HttpResponse response = httpclient.execute(httppost);

WCF

[ServiceContract]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
public class ImageService
{
        [WebInvoke(Method = "POST")]
        public void UploadInspectionPhoto(Stream t)
        {
            // I put a breakpoint here but it never gets here
            // Do something with the stream
        }
}

              </behavior>
          </serviceBehaviors>
      </behaviors>
  </system.serviceModel>

</configuration>

What am I doing wrong?


Is using the WebHttpBinding raw programming model on the service side an option for you? See these two blog posts for detailed step-by-step instructions on how to pull it off.


For anyone that comes across this, as I just did, it turned out that I needed to update the maxReceivedMessageSize for my WCF service. This question helped: WCF REST service 400 Bad Request
