ionic 3 app size is more than 30 mb

问题:

I am using ionic 3 new. When i check my app size is more than 30 mb. i removed my all assets... But still i dont know how this much app size is coming.

And this is my folder of my project:

Node Module = 178mb
resource = 1.2 mb
src= 2.3 mb
www= 14 mb
platform= 468 mb
plugins = 7.8 mb

So in my platform folder i saw more mb. So here inside my Plugin folder images:

Platform --> Android -->

Asssets :14 mb
cordova :3.3 mb
cordova plugin-croswalk: 6 kb
cordovalib:1.3 mb
gradle:56 kb
libs: 2kb
platform_www: 100kb
res: 300kb
src: 200kb
build: 444MB

So inside build:

Generated: 60kb
intermediates: 376 mb
output: 30mb
tmp:0kb

i tried deleting this intermediates and i build it again.. still it automatically shows up..

Please help me , with in two days i need to ship my app.. But my app is very small. its not more than 10 mb...But i dont know 30 mb..
