tl; dr - I cannot get the PhoneGap application to run successfully on WP8.1. There are a number of problems in my problem diagnosis process.
Setup: I created PhoneGap 3.4 for Windows Phone, tested it on Windows Phone 8 using Visual Studio 2012 for WP, and sent it. I have received many crash reports from people with Windows Phone 8.1.
Diagnosing the problem: I went ahead and tried to run the application on the WP8.1 emulator using Visual Studio 2013 for Windows. I get the following error:
Deployment of application to device failed.
Exception from HRESULT: 0x89721500
Then I will try to select "Retarget to Windows Phone 8.1". The application starts and a splash screen appears, but then it crashes and I get the following error:
An exception of type 'System.SystemException' occurred in Microsoft.Phone.Interop.ni.dll but was not handled in user code
Additional information: An unknown error has occurred. Error: 80020006.
If there is a handler for this exception, the program may be safely continued.
