Answer 1

this works for me for API version greater than 18

 mWebView = findViewById(R.id.web_view);   
        String url = "https://duckduckgo.com";

        mWebView.loadUrl(url);  
        mWebView.getSettings().setJavaScriptEnabled(true);

        final String js = "javascript:document.getElementById('search_form_input_homepage').value='android';" +
                "document.getElementById('search_button_homepage').click()";

        mWebView.setWebViewClient(new WebViewClient(){

            public void onPageFinished(WebView view, String url){
                if(Build.VERSION.SDK_INT >= 19){
                    view.evaluateJavascript(js, new ValueCallback() {
                        @Override
                        public void onReceiveValue(String s) {
                        }
                    });
                }
            }
        });

here important is view.evaluateJavascript
