Apk won't install.

Try instead of new project to add existing xdk project and add certificate to that and other thing that it needs.

May be android OS version is a problem . Have you checked that which version your mobile os and the app settings for which version.

It works now. Thank you guys!

Okay, it's not working again. The App is signed and everything should be fine. I deleted it and wanted to install an updated version of it. When I tap "install" nothing happens. I decided to try it out again with the version that has worked previously but this wasn't working too... Don't know what to do right now.

So may be this the file has been corrupted or a virus problem.

nav It's strange because it worked again yesterday in the morning but last night it didn't work again. Everytime it worked it was in the morning or afternoon and everytime it doesn't it's night. It works right now.

Yasharitsu that is strange! Well if you run Night Mode app then your app will not install. If you have Night Mode app stop that and then try to install your apk.
