In you CodeScanner Callback Load the WebView

runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    resultData.setText(result.getText());
                    MywebView.loadUrl(result.getText());
                }
            });

if i create the variable above then it crashes ! – Sep 22 '20 at 02:17
If you WebView and CodeScanner are in different activities then you can use Intent to pass the result from CodeScanner to MainActivity and then load the WebView with it.
