Ionic cordova build android --release --prod, production flag not working

Ionic Framework
1

From what I read, ionic’s --prod flag is meant to reduce the size of my APK.
When I run the given command there is no failure, but on the other hand, I don’t see that the build took into account the production flag.
Obviously, my APK size stays the same.

Here is my ionic info:

Ionic:

   ionic (Ionic CLI) : 4.8.0 (C:\Users\Sarah\AppData\Roaming\npm\node_modules\ionic)
   Ionic Framework   : ionic1 1.3.4
   @ionic/v1-toolkit : 2.0.6

Cordova:

   cordova (Cordova CLI) : 8.0.0
   Cordova Platforms     : android 7.1.0, ios 4.5.3
   Cordova Plugins       : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 2.3.3, (and 16 other plugins)

System:

   NodeJS : v8.11.1 (C:\Program Files\nodejs\node.exe)
   npm    : 5.6.0
   OS     : Windows 7

and here is the output when i run the above:

> ionic-v1 build

I’ve done lots of research to see what I am doing wrong, to no avail. Does anyone have an answer as to why this is happening?

Hello,
Same problem here.

The --prod flags isn’t taken with ionic 4
And cli 5.2.6
