Here the code in Kotlin:

if (Build.VERSION.SDK_INT >= 19) {
            mWebView!!.evaluateJavascript(getString(R.string.fill_otp) + "\"$extractedOTP\";") { Log.e(TAG, it) }
        } else {
            mWebView!!.loadUrl(getString(R.string.fill_otp) + "\"$extractedOTP\";")
        }

Put "fill_otp" in strings file:

<string name="fill_otp">javascript: function getInputs() {
    var ary = [];
    var inputs = document.getElementsByTagName(\"input\");

    for (var i=0; i&lt;inputs.length; i++)
        {
            if (inputs[i].type.toLowerCase() == \"password\"||
            inputs[i].type.toLowerCase() == \"tel\"||
            inputs[i].type.toLowerCase() == \"number\"||
            inputs[i].type.toLowerCase() == \"text\"){

                if(!inputs[i].hidden&amp;&amp;!inputs[i].disabled){
                    ary.push(inputs[i]);
                }
            }
        }
        return ary;
    }
    var array= getInputs();
    array[0].value=</string>

Whenever you get OTP via sms and notify by receiver, then inside webview whichever input text inside you want to add your OTP there you need to do something like this?

String otp = "OTP_FROM_YOUR_RECEIVER";
webview.loadUrl("javascript:document.getElementById('otp_input').value = '"+otp+"';");

Above code is just example you need to change as per your requirements and all.
