Java.lang.runtimeexception: невозможно запустить активность android.view.inflateexception: бинарная линия файла XML #13 ⇐ Android

[Anonymous]

Я новичок в изучении Android. Я буду коротким. Я получаю ошибку, как упомянуто внизу. Я добавил фрагмент через XML. Я искал решения, но до сих пор ни один из них не работал. Где я ошибаюсь? Могу я получить объяснение, почему это происходит? < /P>
