        }
        return data;
    }
}

From the compilation i get an error :

The error indicates that you are calling your get request without passing a HashMap. My suggestion would be to either pass an empty HashMap if you have some URLs that require a body. Else remove it entirely:

public static String Ok_Get(Context context,String url) {
    String data = "";
    OkHttpClient okHttpClient= MyApp.handleSSLHandshake();
    FormBody.Builder builder = new FormBody.Builder();
    builder.build();
    Request request = new Request.Builder().url(url).build();

If you still need it, when you call it make sure you include the HashMap:

Ok_Get(context, "your/url/string/here", Collections.<String, String>emptyMap())
