I developed an app in j2me which is working fine in default emulator. I added 3rd party library in this app but I'm facing a problem when I try to deploy it in device(Mobiles) . I get an error of Undefined Exception. Please help me to solve it.

I'm trying to run a Hello World kind of problem for a HoloLens on emulator but it is showing error:
The following unexpected error occurred during bootstrapping stage
'Connecting to the device '<device>'.': NullReferenceException - Object reference not set to an instance of an object. [0x80004003]
I have tried making a new project, reinstalling emulator and checked Hyper-V on my system
Please refer to the Troubleshooting section of https://learn.microsoft.com/en-us/windows/mixed-reality/using-the-hololens-emulator. I suspect you're hitting an installation issue where XDE is installed to the wrong folder. The documentation includes a solution for this. Please let me know if this does not resolve the issue.
i'm new to react native and native apps in general and i'm using windows 10.
i have downloaded java and android studio and configured path variables.

I am getting the following error when trying to deploy WP8 cocos2dx project on device.
Could not find file 'E:\Projects\cocos2d-x-2.2.1\projects\MyProject\proj.wp8\ARM\Debug\XapCacheFile.xml'. Please rebuild the solution and try again.Deployment of application to device failed.
I can see XapCacheFile.xml was generated in proj.wp8\Debug folder, but this seems to generated when deploying for emulator.
Can anyone tell me why this is happening.
Simply Clean and Rebuild the solution.

I tried to launch my project, but i got this error while compiling it on the simulator.WorkOut is the name of my project.
Couldn't register com.AE557593PG.WorkOut with the bootstrap server. Error: unknown error code.
Try making sure the app isn't running on the simulator already. Worst case scenario, quit and restart both Simulator and Xcode. That's always fixed this for me.
