Xamarin.Mobile is an API for accessing common platform features, such as reading the user's address book and using the camera, across iOS, Android, and Windows Phone.

The goal of Xamarin.Mobile is to decrease the amount of platform-specific code needed to perform common tasks in multiplatform apps, making development simpler and faster.

Xamarin.Mobile is currently a preview release and is subject to API changes.

Note: The Windows Phone 7.1 version of the library requires the Microsoft.Bcl.Async NuGet package. You'll need to restore this package to use the samples or download this package to any WP7 app using Xamarin.Mobile.

Examples

To access the address book (requires READ_CONTACTS permissions on Android):

using Xamarin.Contacts;
// ...

var book = new AddressBook ();
//         new AddressBook (this); on Android

if (!await book.RequestPermission()) {
	Console.WriteLine ("Permission denied by user or manifest");
	return;
}

foreach (Contact contact in book.OrderBy (c => c.LastName)) {
	Console.WriteLine ("{0} {1}", contact.FirstName, contact.LastName);
}

To get the user's location (requires ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION permissions on Android):

using Xamarin.Geolocation;
// ...

var locator = new Geolocator { DesiredAccuracy = 50 };
//            new Geolocator (this) { ... }; on Android

Position position = await locator.GetPositionAsync (timeout: 10000);

Console.WriteLine ("Position Status: {0}", position.Timestamp);
Console.WriteLine ("Position Latitude: {0}", position.Latitude);
Console.WriteLine ("Position Longitude: {0}", position.Longitude);

To take a photo:

using Xamarin.Media;
// ...

var picker = new MediaPicker ();
if (!picker.IsCameraAvailable)
	Console.WriteLine ("No camera!");
else {
	try {
		MediaFile file = await picker.TakePhotoAsync (new StoreCameraMediaOptions {
			Name = "test.jpg",
			Directory = "MediaPickerSample"
		});

		Console.WriteLine (file.Path);
	} catch (OperationCanceledException) {
		Console.WriteLine ("Canceled");
	}
}

On Android (requires WRITE_EXTERNAL_STORAGE permissions):

using Xamarin.Media;
// ...

protected override void OnCreate (Bundle bundle)
{
	var picker = new MediaPicker (this);
	if (!picker.IsCameraAvailable)
		Console.WriteLine ("No camera!");
	else {
		var intent = picker.GetTakePhotoUI (new StoreCameraMediaOptions {
			Name = "test.jpg",
			Directory = "MediaPickerSample"
		});
		StartActivityForResult (intent, 1);
	}
}

protected override async void OnActivityResult (int requestCode, Result resultCode, Intent data)
{
	// User canceled
	if (resultCode == Result.Canceled)
		return;

	MediaFile file = await data.GetMediaFileExtraAsync (this);
	Console.WriteLine (file.Path);
}
