Android：如何将parse.com链接到Facebook

Question

我正在研究ParseFacebookUser。从其文档中，我将facebook登录模块编码如下：

代码：

@Override  
    protected void onResume() 
    {  
        super.onResume();  
        ....

        Parse.initialize(this, "XXX", "XXX"); 
        ParseFacebookUtils.initialize(this);

        // FB: Logs 'install' and 'app activate' App Events.
        AppEventsLogger.activateApp(this);

        List<String> permissions = Arrays.asList("user_birthday", "user_location", "user_friends", "email", "public_profile");
        ParseFacebookUtils.logInWithReadPermissionsInBackground(this, permissions, new LogInCallback() 
        {
              @Override
              public void done(ParseUser user, ParseException err) 
              {
                    if (user == null) 
                    {
                        Log.d("MyApp","Uh oh. The user cancelled the Facebook login.");
                    } 
                    else if (user.isNew()) 
                    {
                        Log.d("MyApp", "User signed up and logged in through Facebook!");
                    } 
                    else 
                    {
                        Log.d("MyApp", "User logged in through Facebook!");
                    }
              }
        });


    }

清单：

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/MyTheme" >
        <activity
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

        <activity android:name="com.abc.user.LoginActivity"             android:screenOrientation="portrait"/>
        <activity android:name="com.abc.user.RegisterActivity"              android:screenOrientation="portrait"/>
        <activity android:name="com.abc.user.User_leaderboard"              android:screenOrientation="portrait"/>   
        <activity android:name="com.facebook.LoginActivity" 
                        android:theme="@android:style/Theme.Translucent.NoTitleBar" android:label="@string/app_name" /> />

        <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>   

    </application>

问题：

引起：登录尝试失败：无法启动FacebookActivity。请确保您已将FacebookActivity添加到AndroidManifest。没有页面重定向登录facebook。上面的代码有什么问题？

谢谢！

Answer 1

您尚未在Manifest文件中包含Facebook登录活动。加上这个。

<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" />
