Getting a picture from Android to a WCF Service

Had a fun time today getting a picture taken from an Android 2.3.4 HTC Vivid to my Mobile WCF Platform. Oddly enough, I could not find any tutorials on it for Monodroid like there are for MonoTouch. Piecing together several stackoverflow posts, I finally figured it out. Here is a possible solution (most likely not the best):

At the top of your class, add the following:

private string _imageUri;
private ImageView imageView;

private Boolean isMounted {
            get {
                return Android.OS.Environment.ExternalStorageState.Equals(Android.OS.Environment.MediaMounted);
            }
        }

Inside your Button Click Event:

     var uri = ContentResolver.Insert(isMounted ? Android.Provider.MediaStore.Images.Media.ExternalContentUri : Android.Provider.MediaStore.Images.Media.InternalContentUri, new ContentValues());
     _imageUri = uri.ToString();
     var i = new Intent(Android.Provider.MediaStore.ActionImageCapture);
     i.PutExtra(Android.Provider.MediaStore.ExtraOutput, uri);
     StartActivityForResult(i, 0);

Right below your Click Event function (or anywhere inside the Activity Class you're in):

protected override void OnActivityResult(int requestCode, Result resultCode, Intent data) {
            if (resultCode == Result.Ok && requestCode == 0) {
                imageView = FindViewById<ImageView>(Resource.Id.ivThumbnail);
                imageView.DrawingCacheEnabled = true;

                imageView.SetImageURI(Android.Net.Uri.Parse(_imageUri));

                btnUploadImage.Visibility = ViewStates.Visible;
            }
        }

Then inside your "Upload Button Click" function:

Bitmap bitmap = imageView.GetDrawingCache(true);
MemoryStream ms = new MemoryStream();

// Note anything less than 50 will result in very pixelated images from what I've seen
bitmap.Compress(Android.Graphics.Bitmap.CompressFormat.Jpeg, 100, ms);

// At this point set your Byte[] variable/property with ms.ToArray();
// for instance I have a SyncFile object with a FileData Property, so I use
// SyncFile sFile = new SyncFile() { FileData = ms.ToArray(); };

Effectively this code captures a picture, puts it in an ImageView as a thumbnail on the Activity and then upon hitting your Upload Button it converts the image into a Byte Array after compressing it (or not like in my case) and from there call your WCF service upload function.

Hopefully that helped someone out.
