How to add an Android Asset Pack in an Ionic project

I have an Cordova project I recently brought over to Ionic and all seem to be going along well.
I believe I need to create an Android asset pack, because I have too many images for the Android app store size limit.

The only details I found about the layout of source of an asset pack I found is:
[Integrate asset delivery (native)  |  Android Developers](https://Integrate Asset Delivery (native)) on the android.com.

I’m am going to try following these steps.
Is this the right idea? Is there something more specific to doing it with an ionic app?

Are there any tools that help me with the creation such directory scheme?
By tools I mean command line, in Visual Studio or in Android studio.

Any help in this area would be appreciated.
