'TAG' tiene acceso privado en 'android.support.v4.app.FragmentActivity'

Casi todo en mi actividad está funcionando bien, excepto donde se hace referencia a TAG . TAG obtiene una línea roja y dice: 'TAG' has private access in 'android.support.v4.app.FragmentActivity' . No tengo ni idea de lo que esto significa, así que por favor ayúdenme aquí.

MainActivity (sin importaciones) –

• Hacer algunas cosas de la interfaz de usuario de Android en un subproceso no UI
• Supervisar la memoria ocupada por mi aplicación en Android
• Utilizar la biblioteca de Zxing en PreviewFrame para aumentar la realidad
• Significado de android @override
• Mi listview no rellena el padre
