How to test my app on my device without Ionic serve

Hello,
I’m new to ionic and i just finished my first app and it work perfectly on my browser, but I just wanna know how to run it on my android device without the need of ‘ionic serve’ being launched on my PC, I mean my app currently works on my mobile but only if I run ‘ionic serve’ on my pc is there any way to make it run without the need of that. Or I’m missing something ?

Usage Syntax: ionic cordova run [] [options]

For Android :ionic cordova run android

did u even read my problem ?I said

my app currently works on my mobile but only if I run ‘ionic serve’ on my pc is there any way to make it run without the need of that

This is the documentation link.

U can use: ionic cordova build android

This will generate .apk file.

ionic cordova run android --will build .apk file and execute it in Your mobile device if ur connected with a mobile device. After that u can even launch .apk directly. If u have any doubt go through above documentation link.
