添加Facebook登錄名時應用崩潰

Question

在我添加Facebook登錄名之前，我的應用程序運行良好。 我所做的一切與在其他應用程序上所做的相同，但仍然會出錯。 我添加了Facebook SDK，並對其進行了初始化。 我在Facebook網站上注冊了我的應用程序。 還是不明白問題所在。

Answer 1

Facebook權限應分開：

login.setReadPermissions("public_profile","email");

並且不需要：
login.setOnClickListener(new View.OnClickListener()
因為在單擊login按鈕時它將調用：
login.registerCallback(callbackManager, new FacebookCallback<LoginResult>()方法來調用com.facebook.FacebookActivity
