Subject: Re: [mono-android] getting a pic from the camera
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?
