How to reduce the size of apk?

UPDATE: The minification is now part of the standard build process for TypeScript and JavaScript.

Check out the following post for a simple integration of uglify:

Ionic 2 - app.bundle.js - Minification

UPDATE: This is no longer needed because it’s now part of the build process for TS and JS. @tonyawad88 First of all I would recommend you to not modify anything under node_modules (unless you want to apply a temporary fix) because your changes will be lost when you update your packages. If you want to customize your build process you could use the gulpfile.js file for that purpose. Disclaimer: I still don’t have any experience with gulp/browserify so this is just a quick example and most p…

Furthermore I would recommend to exclude the source maps from the .apk file by further modifying the code like this (check out the full code in the other post):

// ...
      buildBrowserify({ browserifyOptions: { debug: !isRelease } }).on('end', function(){
        minifyScripts('www/build/js', done);
      });
// ...

Note that this is a temporary workaround, AFAIK the built-in minification is on the way and I guess that it will be released pretty soon.
