Description Stephan Desmoulin 2013-01-31 17:18:20 UTC
I have encountered an exception today in Android 4.2.1 Jellybean, Samsung Galaxy S3, Monodroid 4.4.55.104956787, Windows 8 x64, Visual Studio 2012 Ultimate SP1.

The exception occurs when passing an array of Object variables to AsyncTask.Execute(). I've included a stack trace below for reference. I do not believe that Windows or Visual Studio have any bearing, as the same project deployed to an Android 2.3.5 device (Motorola Electrify) does not exhibit the same issue.

I would be happy to perform any additional troubleshooting and debugging to assist in the resolution of this issue.

Thanks!

Stephan Desmoulin

Comment 1 Stephan Desmoulin 2013-01-31 17:54:10 UTC
Additional notes:

I have not been able to replicate if the parameters passed to AsyncTask.Execute are all string values. It appears that a mixture of data types being passed causes this exception.
Comment 2 Miguel de Icaza [MSFT] 2013-05-22 15:52:02 UTC
Stephan, to help us accelerate this, do you have a code snippet that shows what exactly you were doing that caused this?
Comment 3 Jonathan Pryor 2014-01-10 21:58:12 UTC
Please provide a repro, or try a more recent version. (There have been a number of marshaling fixes since 4.4.x.)
