Ionic Build in Android not taking in account device width

I am running my android app on my device after running Gulp Tasks to uglify JS, and Minify Css. My app seems to run smoothly on Chrome Web(in device views as well) when i do ionic serve. But when I run command Ionic Run Android. The resulting build doesn’t take account of my device width and the first page of my app is maximized view. The index.html in my android/assets/www/ seems fine, cordova.js and all the libraries are there too. No error is generated!. Am i missing a trick here?
Below is my info:
Cordova CLI: 5.1.1
Gulp version: CLI version 3.9.1
Gulp local: Local version 3.9.1
Ionic Version: 1.0.0
Ionic CLI Version: 1.7.12
Ionic App Lib Version: 0.6.5
OS: Distributor ID: Ubuntu Description: Ubuntu 14.04 LTS
Node Version: v0.12.7

Ps: I used to make builds on my app normally before I resorted to the trick of Gulp Uglification/Minification. After that I am facing this issue. Thanks in advance.
