###Introduction

This sample shows how to use query Office 365 API service from a Xamarin Android project.

The sample builds a Xamarin binding to ADAL's native Android Library. The generated binding is then referenced by specific Android projects to authenticate and get tokens for Office 365 API resources.

ADAL team is planning on adding more robust support to Xamarin projects, but until then, Xamarin bindings will help you build the ADAL library you need for your Android projects. You can download and use ADAL v3.0 preview if you are interested to see ADAL vNext. ADAl v3.0 is a PCL and comes with support for Xamarin Android and iOS projects as well. However, please remember that ADAL v3.0 is still a preview and is not recommended to use in production. Here is an ADAL sample that uses ADAL v3.0 preview.

This sample has threee projects:

####XamarinOffice365.AdalBindings This is the actual Xamarin binding project. Read more here to understand how to build the Xamarin binginds project with the latest ADAL Android Library.

####XamarinOffice365.AndroidHelloworld A simple Xamarin Hello World that authenticates and gets a token for Office 365 API discovery service. Useful if you want to have a simple project for getting started with using the ADAL Bindings for Xamarin Android.

####XamarinOffice365.Droid This project describes the code to interact with the Exchange Contacts API and query your contacts.

To run this sample, you need:

1. Visual Studio 2013
2. Office 365 Developer Subscription

From your Git Shell or command line:

git clone https://github.com/OfficeDev/XamarinAndroidO365.git

1. Open the project in Visual Studio 2013.
2. Go to XamarinOffice365.AdalBindings project node.
3. Build the XamarinOffice365.AdalBindings project.

Follow the steps here to manually register an application for your Android client application and copy the following from the portal:

1. Client Id
2. Redirect URI

Under permissions to other applications, select Office 365 Exchange Online as the application and set the following permissions Read users' contacts.

Insert the copied Client Id and Redirect URI in the respective variables where it says:

internal string ClientId = "[insert-your-client-id]";
internal string RedirectUri = "[insert-your-redirect-uri]";

Hit Debug or Press F5 to build and debug the application!
