looks like you are running your app in the browser. Now build your app with this command: 

ionic cordova build android

Or connect USB and turn on debug mode from developer options then run this cmd:

ionic cordova run android

If you will run your app with USB, so with USB you can inspect your device app in chrome by running this URL:

chrome://inspect/#devices

Hope this helps you...

    Thanks for reply. The app work on mobile after the build. but this console error is confusing. I want to find why error occur instead of cordova not available warning – No One Aug 21 '19 at 05:10
  • Have you found the origin of that error? I have the same using Ionic 5, and that error prevents me from running unit testing with the command npm test – Pierre May 03 '20 at 02:52
