I don't think you can post data with WebView. You may want to post it using some HTTP library, and load the response HTML into WebView — Vladyslav Matviienko, Jan 29 '19 at 12:39
@VladyslavMatviienko yes we tried that too, Can you suggest me how to post — Manjunath, Jan 29 '19 at 12:42
@VladyslavMatviienko i tried to follow this tutorial https://androidexample.com/How_To_Make_HTTP_POST_Request_To_Server_-_Android_Example/index.php?view=article_discription&aid=64 — Manjunath, Jan 29 '19 at 12:45
if you want to just post data on the server then you can use retrofit. — Uday Nayak, Jan 29 '19 at 13:30
