Ionic 3 App Size for android is more then compared to ionic 2

I am working in Ionic for couple of months. I developed ionic 2 App with more 10pages and App size was 6Mb after Apk Generated, but in ionic 3 I have not even used more than 8pages and less lines of code then compared to Ionic 2 App. Still my Ionic 3 App Size is 35Mb. Any solution for this?

Note: No images are used for both App,

and is it required to keep .module.ts in all the pages which is new feature in Ionic 3.

You just need to build your project using below CLI: It builds the application for production with very small package size. You can see all the build CLI options here.

ionic cordova build android --prod

Q: is it required to keep .module.ts in all the pages which is new feature in Ionic 3?

A: This is not a must thing. But it is a really awesome feature. It will significantly boost your app's performance.You can read more about lazy loading here.

Check if you are using cordova-plugin-crosswalk-webview in your new project. This plugin usually adds ~20-30MB to your final .apk size.

You will need an angular-module for every page that has an @IonicPage decorator. The main advantage of this is that you can utilize lazy-loading (load pages when they are needed, not all of them when the app starts) when you just push a string onto the nav-stack like this: this.nav.push('IonicPageName'). And of course you have a modularized application which is always good from architecture point of view.

Have a look at the following blog entries by the ionic-team on lazy-loading
