Hi Wally,
Actually you can do something useful with the intent you're getting back from
the activity result.
protected override void OnActivityResult(int requestCode, Result resultCode,
Intent data)
{
base.OnActivityResult(requestCode, resultCode, data);
if (requestCode == TakePictureRequestCode && resultCode == Result.Ok)
{
var dataUri = data.ToURI();
var imageView = FindViewById<ImageView>(Resource.Id.selected_picture);
imageView.SetImageURI(Android.Net.Uri.Parse(dataUri));
}
}
This is basically the thing to get a picture back from the camera :)

Onderwerp: [mono-android] getting a pic from the camera
I'm trying to start the camera application and get an image back. I think I
should be able to get the image back in the OnActivityResult method.
Unfortunately, I am missing something as I don't seem to get anything back.
All of what look to be the interesting pieces of the data Intent seem to be
null. I suspect that the problems are on my end. I get the "data" object
back. Unfortunately, I don't get a file uri that I can open as an image. I
don't get anything back. Any suggestions on how to get the image back when I
take a picture?
Wally
