POUsing SimpleAdapter with Mono for Android
text
Body
copied!<p>I have created a FileDialog activity in Mono for Android. However, it seems to me that there is an issue with some MonoObject to JavaObject casting when using ListView simpleadapter. After I have left onCreate the VM crashes with the following stacktrace: </p> <pre><code>07-05 15:04:46.493 D/FileDialogActivity( 3430): Left OnCreate 07-05 15:04:46.503 D/AndroidRuntime( 3430):

Or have any clues to what happens here??</p>
