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

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.

MediaPicker and FilePicker

The time has finally come for brand new media capabilities in Xamarin.Essentials. These new APIs enable you to easily access device features such as picking a file from the system, selecting photos or videos, or having your user take a photo or video with the camera.

async Task TakePhotoAsync()
{
    try
    {
        var photo = await MediaPicker.CapturePhotoAsync();
        await LoadPhotoAsync(photo);
        Console.WriteLine($"CapturePhotoAsync COMPLETED: {PhotoPath}");
    }
    catch (Exception ex)
    {
        Console.WriteLine($"CapturePhotoAsync THREW: {ex.Message}");
    }
}

App Actions

App actions, shortcuts, and jump lists have all been simplified across iOS, Android, and UWP with this new API. You can now manually create and react to actions when the user selects them from the app icon.

try
{
    await AppActions.SetAsync(
        new AppAction("app_info", "App Info", icon: "app_info_action_icon"),
        new AppAction("battery_info", "Battery Info"));
}
catch (FeatureNotSupportedException ex)
{
    Debug.WriteLine("App Actions not supported");
}

Contacts

Does your app need the ability to get contact information? The brand-new Contacts API has you covered with a single line of code to launch a contact picker to gather information:

try
{
    var contact = await Contacts.PickContactAsync();

    if(contact == null)
        return;

    var name = contact.Name;
    var contactType = contact.ContactType; // Unknown, Personal, Work
    var numbers = contact.Numbers; // List of phone numbers
    var emails = contact.Emails; // List of email addresses 

}
catch (Exception ex)
{
    // Handle exception here.
}

So Much More

That is just the start of brand-new features in Xamarin.Essentials 1.6. When you install the latest update, you will also find new APIs including Screenshot, Haptic Feedback, and an expanded Permissions API. Additionally, there has been tweaks and optimizations to existing features and of course some bug fixes.
