Runtime Exception in windows build

Question

I am able to generate & install windows phone build in my Microsoft Lumia 640. Its running on Windows OS 8.1.

But as soon as I run application generated by CN1 build server, it gives error

An internal application error occurred: java.lang.RuntimeException Unsupported operation as per below screen shot.

For a testing purpose I created new CN1 Project and without changing any code / theme.res I just sent windows phone build and it ended up with the same error.

Unfortunately I didnt get any log output from windows phone, as it doesnt support Logcat like Android. Also I tried to grab Isolated Storage by WP Power Tools but there was nothing in it.

Anyone faced / facing this in Codename One windows phone build ?

Answer 1

The Windows Phone port is the least mature of the Codename One ports having gone thru 3 rewrites due to changes from Microsoft.

We are now debating the 4th rewrite, in the meantime some community members did their own port which should be more complete: https://github.com/Pmovil/CN1WindowsPort

So as the short answer I suggest using that. For an explanation on how we got here read on.

The reason we didn't already start with the 4th port was Microsofts project astoria that they suddenly (might have) canceled. We were relying on this project for future Windows Phone support but now that its status is unclear we are in a bind.

We also have the JavaScript port & the Windows desktop port as options for targeting windows phone alleviating some of the problem.

If MS cancels the project for good we'll dedicate the resources for a complete rewrite of the port, but that will take time. However, we don't want to start off on such a huge effort and suddenly be faced with a huge shortcut of Android compatibility.
