Unused HockeyApp component for Android (Xamarin Component Store)

I tried to include the component mentioned above.

http://components.xamarin.com/view/hockeyappios

I created a very simple project based on the Xamarin Studio (Android Ice Cream Sandwich Application) template. Then I added the necessary code to send exceptions to HockeyApp. This code is described on the next page.

http://components.xamarin.com/gettingstarted/hockeyappandroid

Unfortunately, I found a serious problem saving the exception data file

HockeyApp.ManagedExceptionHandler.SaveException (e.ExceptionObject)

This call results in the following error

While studying the problem, I came across the following information

  • The processed exception can be saved without problems.
  • The problem only occurs in the AppDomain.CurrentDomain.UnhandledException handler

AppDomain.CurrentDomain.UnhandledException

string eStr = e.ExceptionObject.ToString();
Java.Lang.Throwable thr = new Java.Lang.Throwable(eStr);
