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 ?
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.
I'm facing a weird problem. When I'm trying to debug my app on Windows Phone Emulator I'm getting this error:
Deployment failed because no Windows Phone was detected. Make sure a phone is connected and powered on.
However Emulator is launched, the app is deployed correctly and I'm able to debug it without any problems. I'm writing this question because this error is a bit annoying. I'm using the same settings on another machine and everything works fine there.
I'm using Visual Studio 2013 Ultimate / Win 8.1 with settings like below:
I found a problem. I have 3 Windows Phone projects, one of them (which was in fact not marked as a startup one) was targeting the physical device, and that caused the problem. Problem was solved by switching Target device in project properties -> Debug to emulator.
I've been trying to get the emulator to work for days. Previously I tried the Windows Phone 8.1 Emulator as well as the Windows 8.1 Simulator and both were stuck at loading the OS.
Earlier today I installed the new Windows 10 Tools and thought I should give it another try with the new Windows 10 Emulator... And no, still the same result.
What's strange is that, the Hyper-V Manager seems to be doing OK. I can see the app displays correctly on the little Preview window (see the box on the left side of the picture below).
Also, breakpoints are hit, the project seems to be running OK.
As many answers have already suggested, I tried letting it running for an hour, but still nothing came up.
Things that I've also tried include uninstalling all the Virtual Machines as well as repairing the WP 8.1 Emulator, nothing has worked so far.
Please help, this has driven me completely insane. :(
Update
Not sure if this would help, but if I change the Windows Phone Emulator Internal Switch to use Private network instead of Internal, I will get a couple of warnings saying Unable to determine the Host IP address and then the Emulator will show up with the Emergency Call screen. Not much I can do from there as the three buttons on the bottom are not functioning at all.
I understand that changing the connection type is not the right way to do it, but this at least tells me that the Emulator can work, it's just a matter of how.
I believe you have two Windows Phone Internal Switch connections and one seems to be unplugged while the other is running. Disable the one that is unplugged and leave the latter. This worked for me after 2days of tinkering. God speed.
Try the following.
Open the Hyper-V Manager
In the Actions pane, click Hyper-V Settings
In the Server pane, select Physical GPUs
Uncheck, Use this GPU with RemoteFX
Click OK to save/close.
Attempt to start the Windows Phone emulator VM from within Hyper-V Manager or Visual Studio.
I solved this problem by simply adding XDE.EXE as an exception to my Windows Firewall.
Just today
Many times it is not stuck. It just does take too long to start. I have an 8 core processor and it took like 5 minutes to launch, I tought it was stuck but it did launch.

when you set it to private network, Windows can't interact with your WP Emulator. Open Network Adapter, and try disable and try start emulator again, then enable again this adapter if it is not work *
I contacted the Visual Studio Team a couple of weeks ago and looks like they have fixed this issue in the latest update. And here is how I finally got it all working.
Update your Windows 10 TP to the latest version (currently 10074).
Install the latest Visual Studio 2015 (currently RC).
Install Windows 10 developer tools preview from here (I got
some weird errors with Error code: -2147023294. Ignore them, go
straight to the next step).
Install the standalone Windows SDK for Windows 10 Insider
Preview from here.
Install the Pre-release Microsoft Emulator for Windows 10 Mobile
from here.
That's all! After all these are done, both my Simulator and Emulator are loading up fine.
In my case, deleting the internal switch from Hyper-V virtual switch manager helps, whenever you run your app using emulator as the target, it'll add a new internal switch by itself and the emulator will run normally (no longer stuck on loading screen)
The problem is, I have to do it every single time I restart my PC
The workaround steps to install the Windows SDK and Emulator are no longer needed.
We have released a fix as of 7PM PDT 30 April 2015 for the setup error
Windows 10 SDK 10.0.10069 : The installer failed.
User cancelled installation. Error code: -2147023294"
New setups should no longer encounter this issue.

This worked for me:
Go to Windows Defender.
Add exclusion following path: "C:\Users\UserName\AppData\Local\Microsoft\XDE\YourEmulatorVersion"
YourEmulatorVersion - for example 10.0.14393.9
2 days, tried all that is posted here but nothing worked! Finally, since it is a lot easier nowadays to (re)install windows without loosing your files (3 hours including updates), I just resorted to that. Same thing happened, but then I saw the alert that I had not yet activated my VS to run in developer mode :) Did that, and voila, the emulator now works.
If this might be helpful: my problem started when I installed Android Studio and disabled Hyper-V from Android. Enabling it back for VS just couldn't get me to run it again. But I hear there is a way to run both Android & VS emulators using VS emulator for Android. I will try to see how that works later...
I know the question is old, but none of the above answers worked for me so I write down my two cents:
Go to Hyper-V console and remove all emulators
Go to Devices Management, under network adapters tree node, delete all virtual switches
Run an emulator from Visual Studio and see the magic happen
I'm trying to browse files of my game (windows phone 8.1), but have problems with it. I tried to do it with ISETOOL.exe, but it always starting another emulator. Even with deviceindex option. WP Power Tools program also can not connect to running emulator. How can I browse files on running emulator, not starting another one?
OS language and language of Visual Studio must be the same. I changed language of VS and it's work.
I have a really weird issue that will make me crazy soon I think.
I've installed Visual Studio Express 2013 for Windows to test Windows Store Apps development. I want to use XAML and C#. So, I created a new project from the blank app template and just try to start it. Unfortunatelly it has never worked, the screen stay blocked on the splash screen of my app. No errors in Visual Studio, it just try to launch a Visual Studio Just in Time debbuger for an unhandled exception in .Net framework, but when I select the debugger nohthing happen. There's no trace of an exception in the EventViewer either...I tried local machine and simulator debug...no change !
Sometime i have this message in Visual Studio too but it's not all the time :
I tried everything I found on the internet :
Reset VS settings
Renew developper license
(...)
When I make a new Windows Store App with Javascript it works perfectly..it seems to be only a XAML/C# issue.
Any help would be much appreciated ! Thank you in advance !
My configuration :
Windows 8.1
Visual Studio Express 2013 for Windows Update 1
SSD drive, Intel i7, Lenovo IdeaPad
Ok I fixed it by re-installating all the system. I suppose there was something wrong with the .net Framework. Now it worked well !
EDIT :
I found that was messing the whole system. If I install SQL Server 2012 Express Edition it stop working. So...I switch to another DBMS !
