Necesito ayuda con este archivo para mi aplicación mms. getActivity() provoca un error en la compilación.getActivity() no puede encontrar el símbolo símbolo: método getActivity()
error:cannot find symbol: method getActivity()
He intentado muchas cosas para hacer este trabajo hasta el momento, como extends PreferenceFragment - entonces getActivity() está muy bien, pero esta solución rompe toneladas de otras cosas.
¿Alguien sabe por qué me sale este error?

No entiendo qué espera que haga getActivity()? – njzk2
no está claro ... ¿qué preguntas? –
