Windows 8 app crashes on start and certification fails

[Jochen_M_]

Good evening,

I ported one of my Android apps to Windows 8. When I upload it to Windows Store, everything seems fine. The icon could be extracted etc., but hours later I always receive a message from Microsoft, that my app crashes on the start at because of that it will be refused. On the emulator it all works fine.

Windows Store ist not so important for me, but I ask myself, why it runs perfectly on Android, but not on Windows 8/10 (I mean the "real" Windows 8 - it´s not Windows Phone).

Do you have a hint for me what I can try?

Is it planned that XDK will support Windows 10 universal apps in the future?

XDK is a really great environment - I hope, it will be available for a long time!

Best Regards,
Jochen M.

Jochen -- do not rely on the Emulate tab to test your app, please see this doc page for some reasons why > https://software.intel.com/en-us/xdk/docs/intel-xdk-dev-emulator-limitations -- Regarding IE package apps, the webview in them (especially the Win 8 and Win 8.1 webview) is quite restrictive and much different than what you find on your Android phone. See this blog for some background regarding what a webview is and why you care > http://blogs.intel.com/evangelists/2014/09/02/html5-web-app-webview-app -- See this JS file for some help in resolving the Windows problems > https://github.com/xmnboy/xdk-win8x-compat.js -- it also contains links to additional information.

Thank you Paul. I used App Preview, not the emulator tab. I´m still struggling with installing .appx files directly on my computer, so I must use the App Preview app. I´m sure your links will help me.

To install Windows apps on your desktop machine you need to open up the package you download from the build system and right-click the *.ps1 file inside of it (extract the ZIP file to a temp directory, then right-click the app-name.ps1 file) and choose run with powershell. The Powershell script will take you through the steps required to install the app on your system.
