How to post data for WebView android

Question

I need to post data to Webview.
I found from some of the links the below code:

 WebView webview = new WebView(this);  setContentView(webview);  String url = "http://www.example.com";  String postData = username=my_username&password=my_password";  webview.postUrl(url",EncodingUtils.getBytes(postData, "BASE64")); 

But in my android studio I see EncodingUtils as deprecated
Can anyone help me what is the alternative for EncodingUtils to post data to Android WebView?

Try like below...

Java:

 WebView webview = new WebView(this);  setContentView(webview);   String url = "http://www.example.com";   String postData = "username=" + URLEncoder.encode(my_username, "UTF-8") + "&password=" + URLEncoder.encode(my_password, "UTF-8");  webview.postUrl(url,postData.getBytes()); 

Kotlin:

val webview = WebView(this) setContentView(webview)  val url = "http://www.example.com"  val postData = "username=${URLEncoder.encode(my_username, "UTF-8")}" + "&password=${URLEncoder.encode(my_password, "UTF-8")}" webview.postUrl(url, postData.toByteArray())
