I found this blog helpful:

It will help you set initial zoom level and on seek-change content of webview resizes

// Set the initial progress of seek bar mSeekBar.setProgress(mWebView.getSettings().getTextZoom()/25);

    // Set a change listener for seek bar
    mSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        @Override
        public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
            /*
                public abstract void setTextZoom (int textZoom)
                    Sets the text zoom of the page in percent. The default is 100.

                Parameters
                    textZoom : the text zoom in percent
            */

            // Zoom the web page text
            // We will allow text zooming 25% to 300%
            mWebView.getSettings().setTextZoom(i*25);
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {

        }
    });

Answer 2

You can set the zoom to 0.1f

mWebView.zoomBy(0.1f);

Answer 3

setDefaultZoom is deprecated.

webview.getSettings().setDefaultZoom(WebSettings.ZoomDensity.FAR);

So instead of that you can use like below,

webview.setInitialScale(1);
webview.getSettings().setLoadWithOverviewMode(true); 
webview.getSettings().setUseWideViewPort(true);

This help you to remove

setDefaultZoom(WebSettings.ZoomDensity.FAR).
