Cordova Ionic apk with chrome/chromium webview -

i'm developing arabic android hybrid application using ionic , cordova, seems issues ( not applying font, scrolling not smooth etc...) android 4.0-to 4.4. solve issue tried cocoonjs+webview , issues solved apk size coccoon , webview+ 18mb.

suggest me solution less apk size?, have option in cocoon js reduces apk size? other solution at-least work applying font change less size of apk? option install less size apk , and run-time if user wishes download , add chrome-view installed apk?

even had issue of having slow scrolling. adding overflow-scroll="true" ion-content removes scroll effects, worthy cause scroll lag gone; added , scroll flawless.

so, html like:

<ion-content overflow-scroll="true" class="has-header"> 

and why unable use fonts? have imported correct files in right manner? how import font using css , works good:

@font-face {   font-family: "roboto-regular";   src: url("../fonts/roboto-regular.ttf"); } 

and use in way:

.titlemenu {   font-family: "roboto-regular" !important; }
