pero eso desde donde lo llamo??
Tengo que llamarlo con un AsyncTask(ni puta idea lo que es lo he leido en internet) o directamente en el MainActivity ?
Yo ahora mismo estoy intentando poner un boton que ponga conectar y en ese boton llamar al readJSON (He puesto mil codigos que he encontrado en internet, y el tuyo tambien), y pongo el debug para ver que cuando llega al final, el String que retorna es correcto, pero en la linea
"HttpResponse response = client.execute(httpGet);" se sale.
El error es:
