Android Studio not recognizing changes

For some reason, when I make a change to my code, and then build it: ionic build, ionic capacitor copy, the change is not picked up in the Android Studio. When I run the app, some old version of the code is ran on the app.

I am really stuck on this, any help would be appreciated.


Ionic CLI : 5.4.16 (C:\Users\craig\AppData\Roaming\npm\node_modules\ionic)
Ionic Framework : @ionic/angular 5.0.5
@angular-devkit/build-angular : 0.900.6
@angular-devkit/schematics : 9.0.6
@angular/cli : 9.0.6
@ionic/angular-toolkit : 2.2.0


Capacitor CLI : 1.5.1
@capacitor/core : 1.5.1


Cordova CLI : 9.0.0 (cordova-lib@9.0.1)
Cordova Platforms : none
Cordova Plugins : no whitelisted plugins (0 plugins total)


cordova-res : 0.10.0
native-run : 0.3.0


NodeJS : v12.15.0 (C:\Program Files\nodejs\node.exe)
npm : 6.13.4
OS : Windows 10

npx cap copy is just updating your “template”, you need npx cap sync to update your plugins.

Indeed that’s what I do whenever I want to test my changes:

ionic build --prod && npx cap copy && npx cap sync && npx cap open android

the double & operator will allow you to do all this stuff one-by-one in sync mode.

After that I recommend to do **Build** -> **Clean Project** before launch your app.

Let me know if it works!

Thanks for you help. There are some good tips there.
It looks like my app had Ionic Deploy enabled, so it was installing the right one, then over-writing it in the background with whatever old version was available via Ionic Deploy.
Painful, I lost so much time on this.
