Centralize the support libraries dependencies in gradle

Working with multi-modules project, it is very useful to centralize the dependencies, especially the support libraries.

A very good way is to separate gradle build files, defining something like:

root
  --gradleScript
 ----dependencies.gradle

        ImageView imageView = (ImageView) findViewById(R.id.card_thumbnail_image);
        Bitmap mBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.rose);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
            //Default 
            imageView.setBackgroundResource(R.drawable.rose);
        } else {
            //RoundCorners 
            RoundCornersDrawable round = new RoundCornersDrawable(mBitmap,
                    getResources().getDimension(R.dimen.cardview_default_radius), 0); //or your custom radius
