Question

So I’ve gotten as far as getting the camera to open, take the picture and then return the camera result as follows:

bt.Click += delegate
   {
      Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
      StartActivityForResult(intent, 0);
   };
protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
    {
        base.OnActivityResult(requestCode, resultCode, data);

        if (resultCode == Result.Ok && requestCode == 0)
        {
            string result = data.ToURI();            
        }

The value of result ends up as “#Intent;action=inline-data;B.bitmap-data=true;end”. I don’t really know where to go from here as far as taking the picture result and being able to turn it over to my web-service that will then save it as an image file on the server.

Edit: The final code for anyone with the same problem

bt.Click += delegate
   {
  Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
  StartActivityForResult(intent, 0);
  };
protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
 {
    Bitmap bitmap = (Android.Graphics.Bitmap)data.Extras.Get("data");

    using (var stream = new System.IO.MemoryStream())
    {
      bitmap.Compress(Android.Graphics.Bitmap.CompressFormat.Png, 0, stream);
      byte[] imageBytes = stream.ToArray();
      string base64String = Convert.ToBase64String(imageBytes);

      inst.saveImage(base64String);
    }
 }
    [WebMethod]
    public void saveImage(string stream)
    {
        byte[] imageBytes = Convert.FromBase64String(stream);
        MemoryStream ms = new MemoryStream(imageBytes, 0,
          imageBytes.Length);
        var filepath = "C:\\Temp\\Test.png";

        using (Stream file = File.OpenWrite(filepath))
        {
            ms.CopyTo(file, (int)stream.Length);
        }

    }

Answer 1

The data you get back includes the bitmap data, as your “result” string shows. You can pull the bitmap out of the Intent and compress it out to a stream by doing something like this:

var bitmap = (Android.Graphics.Bitmap) data.Extras.Get("data");

using (var stream = new MemoryStream())
{
    bitmap.Compress(Android.Graphics.Bitmap.CompressFormat.Png, 0, stream);

    // stream now contains the image data
}

You can use any type of .NET stream there, so the MemoryStream is just an example.
