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.
I would suggest creating a new blank ionic app and then repalce the src folder n the blank version with the src folder from your original version - then produce the APK and see what the file size is.
From my own experience the update procedure keeps files in the www and production folders which have been deleted or renamed in the src folder.
