Intro to Xamarin Essentials

In this article we take a look at Xamarin.Essentials, Microsoft’s official cross-platform library for accessing native features in your Xamarin apps.

Xamarin.Forms makes creating a beautiful and functional mobile app possible straight out of the box. Sooner or later, though, you’ll want access to some native functionality of the device. You may need access to the device’s precise location, or maybe to detect a device shake or open the phone dialer.

Of course, Xamarin has access to all of the native APIs that you need, and it’s pretty straightforward to drop down into native code through Dependency Services—although you’ll need some pretty deep knowledge of the underlying platform for some tasks.

That’s where Xamarin.Essentials comes in. It’s an official NuGet package from Xamarin that gives you access to over 30 features across iOS, Android and UWP, all from your shared C## code.

Getting up and running with Xamarin Essentials couldn’t be easier. Simply add the NuGet package, add a little setup code for Android, and it’s ready to use.

Xamarin.Essentials currently offers the following features:

• Accelerometer: Retrieve acceleration data of the device in three-dimensional space.
• App Information: Find out information about the application.
• Barometer: Monitor the barometer for pressure changes.
• Battery: Easily detect battery level, source, and state.
• Clipboard: Quickly and easily set or read text on the clipboard.
• Color Converters: Helper methods for System.Drawing.Color.
• Compass: Monitor compass for changes.
• Connectivity: Check connectivity state and detect changes.
• Detect Shake: Detect a shake movement of the device.
• Device Display Information: Get the device’s screen metrics and orientation.
• Device Information: Find out about the device with ease.
• Email: Easily send email messages.
• File System Helpers: Easily save files to app data.
• Flashlight: A simple way to turn the flashlight on/off.
• Geocoding: Geocode and reverse geocode addresses and coordinates.
• Geolocation: Retrieve the device’s GPS location.
• Gyroscope: Track rotation around the device’s three primary axes.
• Launcher: Enables an application to open a URI by the system.
• Magnetometer: Detect device’s orientation relative to Earth’s magnetic field.
• MainThread: Run code on the application’s main thread.
• Maps: Open the maps application to a specific location.
• Open Browser: Quickly and easily open a browser to a specific website.
• Orientation Sensor: Retrieve the orientation of the device in three-dimensional space.
• Phone Dialer: Open the phone dialer.
• Platform Extensions: Helper methods for converting Rect, Size, and Point.
• Preferences: Quickly and easily add persistent preferences.
• Secure Storage: Securely store data.
• Share: Send text and website uris to other apps.
• SMS: Create an SMS message for sending.
• Text-to-Speech: Vocalize text on the device.
• Unit Converters: Helper methods to convert units.
• Version Tracking: Track the applications version and build numbers.
• Vibrate: Make the device vibrate.

Let’s get started by building a cross-platform app that uses a few device features. It’s going to be a handy little compass app with a battery level indicator—perfect for demonstrating some simple cross platform services.

Xamarin.Essentials 1.6 preview: macOS, media, and more!

Xamarin.Essentials has been a staple for developers building iOS, Android, and Windows apps with Xamarin and .NET since it was first released last year. Now, we are introducing Xamarin.Essentials 1.6, which adds new APIs including MediaPicker, AppActions, Contacts, and more. Not to mention that this release also features official support for macOS! This means that Xamarin.Essentials now offers over 50 native integrations with support for 7 different operating systems. All from a single library that is optimized for performance, linker safe, and production ready. Here is a highlight reel of all the new features:

Welcome macOS

Since the first release of Xamarin.Essentials the team and community have been continuously working to add more platforms to fit developer’s needs. After adding tvOS, watchOS, and Tizen support the next natural step was first class support for macOS to compliment the UWP desktop support. I am pleased to announce most APIs are now supported for macOS 10.12.6 (Sierra) and higher! Take a look at the update platform support page to see all of the APIs that you can leverage on your macOS apps.
