android - How to make post requests with webview?

Question

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

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"));
