android – How to make post requests with webview?

Posted by: admin June 15, 2020 Leave a comment


I want to make an http post request using webview.

webView.setWebViewClient(new WebViewClient(){

            public void onPageStarted(WebView view, String url,
                Bitmap favicon) {
            super.onPageStarted(view, url, favicon);

            public boolean shouldOverrideUrlLoading(WebView view,
                String url) {

            webView.postUrl(Base_Url, postData.getBytes());

            return true;


The above code snippet loads the webpage. I want to access the response of this request.

How can i obtain the response of an http post request using webview?

Thanks in Advance

How to&Answers:

The WebView does not let you access the content of the HTTP response.

You have to use HttpClient for that, and then forward the content to the view by using the function loadDataWithBaseUrl and specifying the base url so that the user can use the webview to continue navigating in the website.


// Executing POST request
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
HttpResponse response = httpclient.execute(httppost);

// Get the response content
String line = "";
StringBuilder contentBuilder = new StringBuilder();
BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
while ((line = rd.readLine()) != null) { 
String content = contentBuilder.toString();

// Do whatever you want with the content

// Show the web page
webView.loadDataWithBaseURL(url, content, "text/html", "UTF-8", null);


First add the support of the http library to your gradle file:
To be able to use

useLibrary 'org.apache.http.legacy'

After this you can use the following code to perform post request in your webview:

public void postUrl (String url, byte[] postData)
String postData = "submit=1&id=236";
webview.postUrl("http://www.belencruzz.com/exampleURL",EncodingUtils.getBytes(postData, "BASE64"));
