To make changes to the webpage, webView needs to be enabled to execute Javascript.
\nThis is done by the API setJavaScriptEnabled()<\/code> which accepts a boolean parameter. True<\/strong> for enabling javascript execution.<\/p>\n

To remove the header and footer, the ids of the same are needed. That can be obtained by checking the JS file of the webpage.<\/p>\n

Say the id for header is page_header<\/code>and that of footer is page_footer<\/code>.<\/p>\n

Assign a string variable to the script javascript:document.getElementById('page_header').remove();<\/code><\/p>\n

This will find the id in that web page and remove it due to the remove()<\/code> method.<\/p>\n

We then just need to execute the above script.
\nwebview.evaluateJavaScript()<\/code> helps us do that. The parameters required are the script and callback. The callback can be null if none is needed.<\/p>\n

Hence to remove the header,<\/p>\n

`String removeHeader = \"javascript:document.getElementById('page_header').remove();\";\nif (Build.VERSION.SDK_INT >= 19) {\n        webView.evaluateJavascript(script, callback);\n\n} else\n    webView.loadUrl(script, null);`\n<\/code><\/pre>\n<\/p><\/div>\n
