Answer 1

However in the answer for the post PCL is deprecated.
Actually , you just need to do the same thing in Share Projects . DependencyService is available in Xamarin.Forms , which you can refer https://learn.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/dependency-service/introduction .
in Forms
public interface ISavePhotosToAlbum
{
void SavePhotosWithStream(string name, Stream data);
}
in iOS
[assembly: Dependency(typeof(SaveToAlbum))]
namespace xxx.iOS
{
public class SaveToAlbum : ISavePhotosToAlbum
{
public void SavePhotosWithStream(string name,Stream stream)
{
var imageData = NSData.FromStream(stream);
var image = UIImage.LoadFromData(imageData);
image.SaveToPhotosAlbum((img, error) =>
{
});
}
}
}
And add the following code in info.plist
<key>NSCameraUsageDescription</key>
<string>App need to access your camera</string>
<key>NSPhotoLibraryAddUsageDescription</key>
<string>App need to access your albums</string> // new in iOS 11 and later
<key>NSPhotoLibraryUsageDescription</key>
<string>App need to access your albums</string>
In addition , if you want to implement it in Android
in Android
[assembly: Dependency(typeof(SaveToAlbum))]
namespace xxx.Droid
{
public class SaveToAlbum : ISavePhotosToAlbum
{
public void SavePhotosWithStream(string name,Stream stream)
{
var documentsPath = Environment.GetFolderPath(Environment.SpecialFolder.Personal);
documentsPath = Path.Combine(documentsPath, "Orders", temp);
Directory.CreateDirectory(documentsPath);
string filePath = Path.Combine(documentsPath, name);
byte[] bArray = new byte[data.Length];
using (FileStream fs = new FileStream(filePath , FileMode.OpenOrCreate))
{
using (data)
{
data.Read(bArray, 0, (int)data.Length);
}
int length = bArray.Length;
fs.Write(bArray, 0, length);
}
}
}
}
