Может ли кто-нибудь мне помочь?

Answer 1

Примечание: ParseFacebookUtils требует Facebook Android SDK v4.x.x from Parse docs

Could not find method com.facebook.FacebookSdk.sdkInitialize 

Это означает, что вам нужно Facebook SDK также. Функция вызова сеанса из SDK для Facebook, которая не существует в вашем проекте.

Answer 2

Вы должны использовать FacebookSdk.sdkInitialize (getApplicationContext()); до setContentView (R.layout.activity_main); как заявляет documentation. Если вам нужна полная facebook login example, проверьте здесь.
