Приложението за Android се срива при влизане във Facebook

Нов съм в Android. Опитвах се да интегрирам вход във FB с приложението си за Android. Следвах всички инструкции на developers.facebook.com за тази интеграция. Въпреки това, когато се опитам да стартирам приложението си, то се срива при стартирането.

Моля, имайте предвид, че вече имам идентификатор на приложението Facebook, маркер за мета данни, маркер за активност на android в моя AndroidManifest.xml.

Оформлението е следното:

Следва кодовият фрагмент за моята LoginActivity:

Следва изключението, което получавам:
