¿Cómo hago que HtmlUnit funcione bajo Android?

Aquí está mi código:

import com.gargoylesoftware.htmlunit.WebClient; import com.gargoylesoftware.htmlunit.html.HtmlPage; final WebClient webClient = new WebClient(); final HtmlPage startPage = webClient.getPage("http://htmlunit.sf.net"); 

Y este es el error que recibo:

• OkHttpClient cerrar la conexión
• El botón de Android muestra diferentes mensajes de Toast dependen del número de clics
• ¿Por qué estoy recibiendo una excepción de puntero nulo aunque hay valor show cuando println?
• AndroidManifest.xml para Gradle instrumentTest
• Añadir acceso directo a la aplicación de Android En la pantalla principal, haga clic en el botón

He incluido casi todos los jar , mientras que una pareja ha sido eliminado porque eran responsables de Eclipse estrellarse. Supongo que he incluido todo lo necesario para que 2 líneas de código.

En la práctica, HtmlUnit está experimentando dificultades para trabajar en Android.

Cualquier consejo sería muy apreciado.

 Document doc = Jsoup.connect("http://jsoup.org/") .timeout(4000) .get(); 

 Connection.Response res = Jsoup.connect("http://example.org") .data("q", username, "password", password) .method(Method.GET) .execute(); Document doc = res.parse(); System.out.println(doc);
