How to display and interact with OKHTTP html response in android Studio using webview or Web browser

I am building an android app. I have build a request using OKHTTP and I get the response as a string composed of html css and js content. This response is actualy a form that the user must use to allow the app to communicate with a given website.

Now I want the user to be able to see that response as an html page and clicks on a button to allow the communictaion. Only problem I don't know how to display that response as an html in webview or in the web browser.

From the MainActivity:

                          Authenticate myAouth = new Authenticate("myCostumerKey","mySecretKey");
                           try {
                               myResponse=myAouth.run("myUrlHere");
                               //System.out.println( myResponse);
                           } catch (Exception e) {
                               e.printStackTrace();
                           }

the Autheticate class

public class Authenticate {
private final OkHttpClient client;
String[] myResponse =new String[2];
public Authenticate( final String consumerKey, final String consumerSecret) {

    client = new OkHttpClient.Builder()
            .authenticator(new Authenticator() {
                @Override public Request authenticate(Route route, Response response) throws IOException {
                    if (response.request().header("Authorization") != null) {
                        return null; // Give up, we've already attempted to authenticate.
                    }

                    System.out.println("Authenticating for response: " + response);
                    System.out.println("Challenges: " + response.challenges());
                    String credential = Credentials.basic(consumerKey, consumerSecret);
                    Request myRequest =response.request().newBuilder()
                            .header("Authorization", credential)
                            .build();
                    HttpUrl myURL = myRequest.url();
                    myResponse[0]= String.valueOf(myURL);
                    return myRequest;
                }
            })
            .build();
}

@RequiresApi(api = Build.VERSION_CODES.KITKAT)
public String[] run(String url) throws Exception {
    Request request = new Request.Builder()
            .url(url)
            .build();


    try (Response response = client.newCall(request).execute()) {
        if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
        myResponse[1]=response.body().string();
        System.out.println(" URL is "+myResponse[0]+" my response body is "+myResponse[1]);

    }

    return myResponse;
}}

Any help would be apriciated.

Kind Regards

You can use the following code to convert the String to HTML and then display it in a WebView 

    try {
        String html = new String(response, "UTF-8");
        String mime = "text/html";
        String encoding = "utf-8";

        myWebView.getSettings().setJavaScriptEnabled(true);
        myWebView.loadDataWithBaseURL(null, html, mime, encoding, null);
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
}
