Description Chris Tossing 2012-03-28 18:14:21 UTC
We can run the media picker sample, although it seemed to return a null image for some reason, but when we try to put almost the same code in our app, it crashes in the Xamarin.Mobile assembly.  We checked the permissions, and the sample does not seem to require any permissions (e.g. the camera permission).

We are getting the following stack trace:

      0x7 in Xamarin.Media.MediaPickerActivity.Touch
      0x158 in Xamarin.Media.MediaPickerActivity.OnCreate
      0x12 in Android.App.Activity.n_OnCreate_Landroid_os_Bundle_
      0x12 in System.Object.36e725bc-2d06-4843-bb15-3a6de0d158e2

Where were you trying this? The simulator, or a device (and which device running what version)?

It turns out we were missing the external storage permission.  The NullReferenceException is not an issue, but the null image is still an issue.  I will file a separate bug for this.

It might be a good idea, if it's not already there, to document that the external storage permission is required to use the MediaPicker class to take photos.
