How To Get ASP.NET Web API to Return JSON

- by mahmood

first remove xml format :

config.Formatters.Remove(config.Formatters.XmlFormatter);

accepts text/html requests and returns application/json responses :

public class BrowserJsonFormatter : JsonMediaTypeFormatter
    {
        public BrowserJsonFormatter()
        {
            this.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
            this.SupportedMediaTypes.Add(new MediaTypeHeaderValue("multipart/form-data"));
            this.SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/json"));
            this.SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/x-www-form-urlencoded"));
            this.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/plain"));
            this.SerializerSettings.Formatting = Formatting.Indented;
        }

        public override void SetDefaultContentHeaders(Type type, HttpContentHeaders headers, MediaTypeHeaderValue mediaType)
        {
            base.SetDefaultContentHeaders(type, headers, mediaType);
            headers.ContentType = new MediaTypeHeaderValue("application/json");
        }
    }

Register like so:

config.Formatters.Add(new BrowserJsonFormatter());

Use OWIN to Self-Host ASP.NET Web API and SignalR

- by mahmood

Startup.cs

[assembly: OwinStartup(typeof(ERPSelfHostServer.Startup))]
namespace ERPSelfHostServer
{
    public class Startup
    {
        // This code configures Web API. The Startup class is specified as a type
        // parameter in the WebApp.Start method.
        public void Configuration(IAppBuilder appBuilder)
        {
            // Configure Web API for self-host. 
            HttpConfiguration config = new HttpConfiguration();
            config.Formatters.Remove(config.Formatters.XmlFormatter);
            config.Formatters.Add(new BrowserJsonFormatter());

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "{controller}/{action}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );


            // Any connection or hub wire up and configuration should go here
            appBuilder.MapSignalR();

            appBuilder.UseWebApi(config);
            
        }
    }
}

Program.cs

static void Main(string[] args)
        {
            // bind to all network interfaces
            //string baseAddress = "http://*:13602/";
            string baseAddress = "http://172.20.63.161:13602";

            using (WebApp.Start<Startup>(baseAddress))
            {
                Thread.Sleep(Timeout.Infinite);
            }
        }

How to update gradle for Android

- by mahmood

To update Android Plugin for Gradle:
You can find the list of available plugin versions in:
Android Studio\gradle\m2repository\com\android\tools\build\gradle\ directory. In my case I have:

  • 1.3.0
  • 1.5.0
  • 2.1.0-alpha3
  • 2.1.0-alpha4

Use the desired version by editing your project build.gradle file.
Example of build.gradle:

dependencies {
    classpath 'com.android.tools.build:gradle:2.1.0-alpha4'
}

To update Gradle:
In your project directory navigate to \gradle\wrapper\ directory and edit:
gradle-wrapper.properties file.
Example: To change from version 2.8 to version 2.10
before: distributionUrl=https\://services.gradle.org/distributions/gradle-2.8-all.zip
after: distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip
At the end in Android Studio select: Tools→Android→Sync Project with Gradle files
