Breakpoints cause app to crash in new Android version 4.2.2

Hi,

I have just updated my HTC One X to:

Android version 4.2.2
HTC Sense version 5.0
Software Number 4.18.206.4
HTC SDK API Level 5.41

and everytime my app hits a breakpoint in either Visual Studio 2010 or Xamarin Studio, it causes an error 'System Null Exception:Loading' and then crashes the app. If i run this on an older android version it runs and breaks fine.

If I remove all break points and run on the new android version, it all works fine. its everytime I hit a break point.

Here is the few lines of code from my output when the break point is hit.

Mono.Android.VisualStudio.MonoAndroidPackage Verbose: 0 : AD7DebugExceptionEvent ctor: An unhandled exception occured.
Mono.Android.VisualStudio.MonoAndroidPackage Verbose: 0 : AD7DebugExceptionEvent GetException: An unhandled exception occured.
Mono.Android.VisualStudio.MonoAndroidPackage Verbose: 0 : AD7DebugExceptionEvent GetException: An unhandled exception occured.
Mono.Android.VisualStudio.MonoAndroidPackage Verbose: 0 : AD7DebugExceptionEvent GetExceptionDescription: An unhandled exception occured.

Hope you guys can help.

Thanks.

Sam

    Right just in case anybody else is having the problem...i fixed it by using Soft break points, however I need to do this everytime my machine starts up.

    Run the following in command prompt

    adb shell setprop debug.mono.env MONO_DEBUG=soft-breakpoints

    Found the solution from THIS thread

  • Thanks, I had the exact same problem. The command prompt thing worked. The adb tool can be found here: <sdk>/platform-tools/. On Windows usually C:\Users\you\AppData\Local\Android\android-sdk\platform-tools
