It was not possible to complete an automatic installation. This might be due to a problem with your network, proxy servers or an unsolvable installation conflict. At this point, you can continue the installation by manually downloading and installing the independent pieces. The list below shows each component that you need to install.

Java JDK

Download the Java JDK v1.7.0 installer to any directory on your disk, double-click the downloaded file and follow the on-screen instructions.

It is very important to install the 32-bit version of Java JDK even if you're using 64-bit Windows. It is also important that Java JDK v1.6 is installed (although it is fine to have Java JDK 1.7 or newer installed at the same time)

Android SDK

Download the Android SDK for Windows version 22.0.0 to any directory on your disk and double-click it to start main SDK installation process. You can install the SDK either system wide or only for your account. You will need to point your IDE to that location after the installation is completed.

Click here in order to start the Android SDK Manager application. In the GUI make sure the following components are installed or selected for installation:

• Android SDK Tools
• Android SDK Platform-tools
• Android SDK Build-tools
• Android API 15
• Android API 19
• Android API 21

 

Once all the required components are selected (you can select others as well, if you wish) start the installation. Click here to open target dir

Download the Android NDK for Windows version r10d to any directory on your disk and double-click it to start the NDK installation.

When the Android SDK installation is finished you might want to start the Android Emulator Manager and create as many emulator images as you might need for your development. This step can be performed at any time, on an as-needed basis.

GTK#

Download the GTK# v2.12.26 installer to any directory on your disk, double-click the downloaded file and follow the on-screen instructions.

Xamarin Studio

Download the Xamarin Studio v5.9.3 installer to any directory on your disk, double-click it and follow the on-screen instructions.

Xamarin

Download the Xamarin v3.11.590 installer to any directory on your disk, double-click it and follow the on-screen instructions.

 

After installation, restart your Windows workstation to make sure all of the installed system services are running.

Xamarin + Visual Studio

 

Xamarin's Visual Studio plug-in lets you build for iOS and Android on Windows.

Yes, it seems impossible but you can build iOS and Android apps alongside Windows apps in Visual Studio. The Xamarin plug-in for Visual Studio provides project types, UI Designers, and build options for both Android and iOS.

Android Apps

 

Once you've installed Xamarin for Windows you can create, build, test, and debug Android apps from within Visual Studio.

Learn from Microsoft how to build cross-platform apps for Android and Windows Phone!

Xamarin's Android UI Designer works in Visual Studio, letting you create your user interface by dragging and dropping controls onto each screen.

The Xamarin Android Player also runs on Windows, and provides a great Android simulator experience for testing your Android apps (read more).

iOS Apps

 

Xamarin brings iOS development to Visual Studio, from UI design to C# coding, deploying, and debugging iPhone and iPad apps. You just need to have a networked Mac to take care of the compiler and host the simulator or plug in a device.

Once installed the development experience is just like any other Visual Studio project. Check out our introduction to Xamarin.iOS for Visual Studio and see how the iOS Designer works.

Xamarin.Forms

 

You can create Android, iOS, and Windows Phone apps - from business logic to user interface - with almost 100% common code using Xamarin.Forms in Visual Studio. You can even use our XAML syntax to declaratively build your screens, with styles, behaviors, and triggers.

Start with our documentation and free downloadable book chapters to learn more.

Cross-Platform Apps

 

Using Portable Class Libraries or Shared Projects, you can write common code, to share with Xamarin.iOS, Xamarin.Android projects, as well as Windows Phone, WPF, Windows RT or other C#-based platforms from inside Visual Studio. Start with our docs on setting up a cross-platform app.
