Did you check console in the inspector? Maybe there’s an error.

yes i checked but there is no any error
its running perfect in the browser too

Connect USB Debugging on mobile then run a app-debug.apk.Open Chrome Remote Devices. check your app on that. click and see console of that mobile

check this cmd

ionic cordova run android --prod --device (if you want to run it on your mobile device using USB cable)

or

ionic cordova build android --prod (if you want to create a apk from it and install it manually)

hi thank-you but when I debug code but not getting any error
