Platform Support

API Usage

Call Media.Current from any project or PCL to gain access to APIs.

Before taking photos or videos you should check to see if a camera exists and if photos and videos are supported on the device. There are five properties that you can check:

/// <summary>
/// Only for Windows. Initialize all camera components, must be called before checking properties below
/// </summary>
/// <returns>If success</returns>
Task<bool> Initialize();

/// <summary>
/// Gets if a camera is available on the device
/// </summary>
bool IsCameraAvailable { get; }

/// <summary>
/// Gets if ability to take photos supported on the device
/// </summary>
bool IsTakePhotoSupported { get; }

/// <summary>
/// Gets if the ability to pick photo is supported on the device
/// </summary>
bool IsPickPhotoSupported { get; }

/// <summary>
/// Gets if ability to take video is supported on the device
/// </summary>
bool IsTakeVideoSupported { get; }

/// <summary>
/// Gets if the ability to pick a video is supported on the device
/// </summary>
bool IsPickVideoSupported { get; }

Photos

/// <summary>
/// Picks a photo from the default gallery
/// </summary>
/// <param name="token">Cancellation token</param>
/// <param name="request">Pick Photos Request</param>
/// <returns>Media file</returns>
/// <exception cref="OperationCanceledException">Thrown when the operation is canceled by user.</exception>
Task<MediaFile?> PickPhotoAsync(PickRequest? request = null, CancellationToken token = default);

/// <summary>
/// Picks multiple photos from the default gallery
/// </summary>
/// <param name="request">Pick Photos Request</param>
/// <param name="multiOptions">Options for picking multiple photos</param>
/// <param name="token">Cancellation token</param>
/// <returns>Media files</returns>
/// <exception cref="OperationCanceledException">Thrown when the operation is canceled by user.</exception>
Task<List<MediaFile>?> PickPhotosAsync(PickRequest? request = null, MultiPickerOptions? multiOptions = null, CancellationToken token = default);

/// <summary>
/// Takes a photo
/// </summary>
/// <param name="request">Camera Photo Request</param>
/// <param name="token">Cancellation token</param>
/// <returns>Media file of photo</returns>
/// <exception cref="OperationCanceledException">Thrown when the operation is canceled by user.</exception>
Task<MediaFile?> TakePhotoAsync(CaptureRequest? request = null, CancellationToken token = default);

Videos

/// <summary>
/// Picks a video from the default gallery
/// </summary>
/// <param name="request">Pick Video Request</param>
/// <param name="token">Cancellation token</param>
/// <returns>Media file of video or null if canceled</returns>
/// <exception cref="OperationCanceledException">Thrown when the operation is canceled by user.</exception>
Task<MediaFile?> PickVideoAsync(VideoPickRequest? request = null, CancellationToken token = default);

/// <summary>
/// Takes a video
/// </summary>
/// <param name="request">Camera Video Request</param>
/// <param name="token">Cancellation token</param>
/// <returns>Media file of new video</returns>
/// <exception cref="OperationCanceledException">Thrown when the operation is canceled by user.</exception>
Task<MediaFile?> TakeVideoAsync(CaptureRequest? request = null, CancellationToken token = default);

Set up

To be able to use this library you need to initialize in in you MauiProgram.cs file as next:

builder.
    .UseMauiApp<App>()
    .UseMpowerKitMediaPlugin(registerInterface: false); // This will register the IMedia interface for you if set to true

Android

By default, the library adds android.hardware.camera and android.hardware.camera.autofocus to your apps manifest as optional features. It is your responsbility to check whether your device supports the hardware before using it. If instead you'd like Google Play to filter out devices without the required hardware, add the following to your AssemblyInfo.cs file in your Android project:

[assembly: UsesFeature("android.hardware.camera", Required = true)]
[assembly: UsesFeature("android.hardware.camera.autofocus", Required = true)]

Other additional setup is not required.

iOS / MacCatalyst

Your app is required to have next keys in your Info.plist

<key>NSCameraUsageDescription</key>
<string>This app needs access to the camera to take photos.</string>


<key>NSMicrophoneUsageDescription</key>
<string>This app needs access to microphone.</string>


<key>NSPhotoLibraryUsageDescription</key>
<string>This app needs access to photos.</string>

<key>NSPhotoLibraryAddUsageDescription</key>
<string>This app needs access to the photo gallery.</string>

If you want the dialogs to be translated you must support the specific languages in your app. Read the iOS Localization Guide

Windows

Add this to your Package.appxmanifest if you want to take photo / video:

<Capabilities>
    <DeviceCapability Name="webcam"/>

    
    <DeviceCapability Name="microphone"/>
</Capabilities>

Permissions

By default, the Media Plugin will attempt to request multiple permissions, but each platform handles this a bit differently, such as iOS which will only pop up permissions once.

Usage

Via a Xamarin.Forms project with a Button and Image to take a photo:

takePhoto.Clicked += async (sender, args) =>
{
    // only for Windwos
    await Media.Current.Initialize();
    
    if (!Media.Current.IsCameraAvailable || !Media.Current.IsTakePhotoSupported)
    {
        DisplayAlert("No Camera", ":( No camera available.", "OK");
        return;
    }

    try
    {
        var file = await Media.Current.TakePhotoAsync(new CaptureRequest
        {
            DesiredDirectory = "Sample",
            DesiredName = "test.jpg"
        });

        image.Source = file.Path; 
    }
    catch (OperationCancelledException oce)
    { 
        // user cancelled
    }
};

Photo & Video Settings

Directories and File Names

These settings are available only for taking photos and videos over CaptureRequest object. These properties are optional. Any illegal characters will be removed and if the name of the file is a duplicate then a number will be appended to the end. The default implementation is to specify a unique time code to each value.

Default Camera

By default when you take a photo or video the default system camera will be selected. Simply set the DefaultCamera on CaptureRequest. This option does not guarantee that the actual camera will be selected because each platform is different. It seems to work extremely well on iOS, but not so much on Android. Your mileage may vary.

var file = await Media.Current.TakePhotoAsync(new CaptureRequest
{
    DefaultCamera = CameraDevice.Front
});
