The standard way to load an URL into a WebView object is using the loadUrl method.

public void loadUrl (String url)

But if we need to load an URL into the WebView submitting POST data, use instead thepostUrl method.

public void postUrl (String url, byte[] postData)

To create the POST data, use a string and encode it.

1
2
3
4
5
String postData = "submit=1&id=236";
 
webview.postUrl(
    EncodingUtils.getBytes(postData, "BASE64"));
