API Usage

Call CrossMedia.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>
/// 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>
/// <returns>Media file or null if canceled</returns>
Task<MediaFile> PickPhotoAsync();

/// <summary>
/// Take a photo async with specified options
/// </summary>
/// <param name="options">Camera Media Options</param>
/// <returns>Media file of photo or null if canceled</returns>
Task<MediaFile> TakePhotoAsync(StoreCameraMediaOptions options);

Videos

/// <summary>
/// Picks a video from the default gallery
/// </summary>
/// <returns>Media file of video or null if canceled</returns>
Task<MediaFile> PickVideoAsync();

/// <summary>
/// Take a video with specified options
/// </summary>
/// <param name="options">Video Media Options</param>
/// <returns>Media file of new video or null if canceled</returns>
Task<MediaFile> TakeVideoAsync(StoreVideoOptions options);

Usage

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

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

    var file = await CrossMedia.Current.TakePhotoAsync(new Plugin.Media.Abstractions.StoreCameraMediaOptions
    {
        Directory = "Sample",
        Name = "test.jpg"
    });

    if (file == null)
        return;

    await DisplayAlert("File Location", file.Path, "OK");

    image.Source = ImageSource.FromStream(() =>
    {
        var stream = file.GetStream();
        file.Dispose();
        return stream;
    }); 
};

Saving Photo/Video to Camera Roll/Gallery

As of Version 2.1.0 (currently in beta) you can now save a photo or video to the camera roll/gallery. When creating the StoreCameraMediaOptions or StoreVideoMediaOptions simply set SaveToAlbum to true. When your user takes a photo it will still store temporary data, but also if needed make a copy to the public gallery (based on platform). In the MediaFile you will now see a AlbumPath that you can query as well.

Android: When you set SaveToAlbum this will make it so your photos are public in the Pictures/YourDirectory or Movies/YourDirectory. This is the only way Android can detect the photos.

IMPORTANT

Android: The WRITE_EXTERNAL_STORAGE, READ_EXTERNAL_STORAGE & CAMERA permissions are required, but the library will automatically add this for you. Additionally, if your users are running Marshmallow the Plugin will automatically prompt them for runtime permissions.

By adding these permissions Google Play will automatically filter out devices without specific hardward. You can get around this by adding the following to your AssemblyInfo.cs file in your Android project:

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

iOS

The library will automatically ask for permission when taking photos/videos or access the libraries.

Windows Phone 8/8.1 Silverlight:

You must set the IC_CAP_ISV_CAMERA permission.

WP 8/8.1 Silverlight only supports photo, not video.

Windows Phone 8.1 RT:

Set Webcam permission.

In your App.xaml.cs you MUST place the following code:

Plugin.Media.MediaImplementation.OnFilesPicked(args);

Windows Store:

Set Webcam permission.

Future Enhancements

• Auto Rotate on Android
• Image Metadata
• Update Andorid Implentation with new Activity
• Return original album path of picked media
