这里是 MainActivity.java，

package com.example.arpit.facebooklogindemo;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;

import com.facebook.CallbackManager;
import com.facebook.FacebookCallback;
import com.facebook.FacebookException;
import com.facebook.FacebookSdk;
import com.facebook.Profile;
import com.facebook.login.LoginResult;
import com.facebook.login.widget.LoginButton;

public class MainActivity extends AppCompatActivity 

    CallbackManager callbackManager;
    LoginButton loginButton;
    TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        FacebookSdk.sdkInitialize(getApplicationContext());

        callbackManager = CallbackManager.Factory.create();

        loginButton = (LoginButton)findViewById(R.id.login_button);

        loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() 
            @Override
            public void onSuccess(LoginResult loginResult) 
                Profile profile = Profile.getCurrentProfile();
                if(profile != null)
                    textView = (TextView)findViewById(R.id.textView);
                    textView.setText(profile.getName());
                
            

            @Override
            public void onCancel() 

            

            @Override
            public void onError(FacebookException error) 

            
        );
    

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data)
        super.onActivityResult(requestCode, resultCode, data);
        callbackManager.onActivityResult(requestCode, resultCode, data);
    

【问题讨论】：

尝试在setContentView(R.layout.activity_main);之前调用FacebookSdk.sdkInitialize(getApplicationContext());。

【参考方案1】：

你还没有初始化 FacebookSDK

根据Caused by: The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize() first.

这里推荐的方法是创建一个应用程序类并在那里初始化 SDK：

public class MyApp extends Application 

    @Override
    public void onCreate() 
        super.onCreate();

        FacebookSdk.sdkInitialize(getApplicationContext());

并更新您的 AndroidManifest：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.arpit.facebooklogindemo">

    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:name=".MyApp"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

         //from http://developers.facebook.com
        <meta-data android:name="com.facebook.sdk.ApplicationId"
            android:value="@string/app_id"/>

        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        //from http://developers.facebook.com
        <activity android:name="com.facebook.FacebookActivity"
            android:configChanges=
                "keyboard|keyboardHidden|screenLayout|screenSize|orientation"
            android:theme="@android:style/Theme.Translucent.NoTitleBar"
            android:label="@string/app_name" />

    </application>

</manifest>
