整体来说，Facebook在国际化中做的是非常好的。也是，Twitter和YouTube都是Google自己家的，在中国政府受挫之后，就不方便投入太多，怎么做都好像一个血脉，一个味道。

然后Facebook就不一样，小札的丈母娘祖上就是中国的，而且小札年轻，特别喜欢和挑战新的事务。。据说，Facebook为了在非洲的使用体验，专门派工程师到非常调研，非常到位的。

Facebook 的开发者支持分成两块：

账户登录 Account login，和 Account Kit 。

提供的这两个服务，都提供了各种平台的支持，ios,andorid,web,mobilePhone等等。

Account Kit 提供电话号码和邮箱登录功能，无需玩家记忆任何其他密码。

“Facebook 登录”让玩家能够使用他们现有的 Facebook 帐户两步轻松完成帐户注册。

两者结合使用，效果更好 — 可用于壮大您的客户群。

2018 年 8 月之前，Account Kit 不会收取任何短信费用，之后会按照标准的短信费率，对每月确认短信数量超出 10 万的应用收费。

应该说，这两个功能属于异曲同工的作用，具体的使用可以参考产品和业务的需要进行选型，。。在开发的时候，可以同时继承和包装，需要的时候，直接使用。

AndroidSDK文档：https://developers.facebook.com/docs/accountkit/android

客户端SDK_android下载：https://developers.facebook.com/docs/android

一，用户登录

好了，下面开始进行具体的步骤了：：

1，跟所有的三方账户一样，注册开发者账户，创建应用，获得应用编号口令什么的。

2，gradle配置

repositories {
  jcenter()
}

dependencies {
  compile 'com.facebook.android:account-kit-sdk:4.+'
}
{
  jcenter()
}

dependencies {
  compile 'com.facebook.android:account-kit-sdk:4.+'
}

3，配置manifest

<meta-data android:name="com.facebook.accountkit.ApplicationName"
           android:value="@string/app_name" />
<meta-data android:name="com.facebook.sdk.ApplicationId"
           android:value="@string/FACEBOOK_APP_ID" />
<meta-data android:name="com.facebook.accountkit.ClientToken"
           android:value="@string/ACCOUNT_KIT_CLIENT_TOKEN" />

<activity
  android:name="com.facebook.accountkit.ui.AccountKitActivity" />
 android:name="com.facebook.accountkit.ApplicationName"
           android:value="@string/app_name" />
<meta-data android:name="com.facebook.sdk.ApplicationId"
           android:value="@string/FACEBOOK_APP_ID" />
<meta-data android:name="com.facebook.accountkit.ClientToken"
           android:value="@string/ACCOUNT_KIT_CLIENT_TOKEN" />

<activity
  android:name="com.facebook.accountkit.ui.AccountKitActivity" />

根据应用的情况，可能需要更多的配置，允许AccountKitActivity的启动，

<activity
  android:name="com.facebook.accountkit.ui.AccountKitActivity"
  android:theme="@style/AppLoginTheme"
  tools:replace="android:theme" />

  android:name="com.facebook.accountkit.ui.AccountKitActivity"
  android:theme="@style/AppLoginTheme"
  tools:replace="android:theme" />

4*，如果想禁用应用内事件，可以加入。。这里默认的value是true。。这里的应用内事件表示 AccountKit 登录展示，AccountKit登录开始，AccountKit登录尝试，AccountKit的登录。这里的统计可以在控制面板的漏斗里面看到。

<meta-data android:name="com.facebook.accountkit.FacebookAppEventsEnabled"
           android:value="false"/>
 android:name="com.facebook.accountkit.FacebookAppEventsEnabled"
           android:value="false"/>

5，检查当前会话，意思就是登录之后的回调类似于。当在开发者的控制面板里启用客户端的访问口令流程，登录状态就会传给客户端程序。

import com.facebook.accountkit.AccountKit;
import com.facebook.accountkit.AccessToken;

AccessToken accessToken = AccountKit.getCurrentAccessToken();

if (accessToken != null) {
  //Handle Returning User
} else {
  //Handle new or logged out user
}
 com.facebook.accountkit.AccountKit;
import com.facebook.accountkit.AccessToken;

AccessToken accessToken = AccountKit.getCurrentAccessToken();

if (accessToken != null) {
  //Handle Returning User
} else {
  //Handle new or logged out user
}

6，短信登录流程。

import com.facebook.accountkit.AccountKit;

public static int APP_REQUEST_CODE = 99;

public void phoneLogin(final View view) {
  final Intent intent = new Intent(getActivity(), AccountKitActivity.class);
  AccountKitConfiguration.AccountKitConfigurationBuilder configurationBuilder =
    new AccountKitConfiguration.AccountKitConfigurationBuilder(
      LoginType.PHONE,
      AccountKitActivity.ResponseType.CODE); // or .ResponseType.TOKEN
  // ... perform additional configuration ...
  intent.putExtra(
    AccountKitActivity.ACCOUNT_KIT_ACTIVITY_CONFIGURATION,
    configurationBuilder.build());
  startActivityForResult(intent, APP_REQUEST_CODE);
}
 com.facebook.accountkit.AccountKit;

public static int APP_REQUEST_CODE = 99;

public void phoneLogin(final View view) {
  final Intent intent = new Intent(getActivity(), AccountKitActivity.class);
  AccountKitConfiguration.AccountKitConfigurationBuilder configurationBuilder =
    new AccountKitConfiguration.AccountKitConfigurationBuilder(
      LoginType.PHONE,
      AccountKitActivity.ResponseType.CODE); // or .ResponseType.TOKEN
  // ... perform additional configuration ...
  intent.putExtra(
    AccountKitActivity.ACCOUNT_KIT_ACTIVITY_CONFIGURATION,
    configurationBuilder.build());
  startActivityForResult(intent, APP_REQUEST_CODE);
}

APP_REQUEST_CODE 是您用于追踪登录流程的自定义代码。它可以是任何整数，但需要由您的应用程序设置。
初始化 intent（意图）附加程序时，请务必指定与 Facebook 开发者门户网站面板中的应用授权设置相匹配的 AccountKitActivity.ResponseType：如果您的应用面板的启用客户端访问口令流程开关设置为“开”，则指定为TOKEN，如果设置为“关”，则指定为 CODE。

7,邮箱登录流程

import com.facebook.accountkit.AccountKit;

public static int APP_REQUEST_CODE = 99;

public void emailLogin(final View view) {
  final Intent intent = new Intent(getActivity(), AccountKitActivity.class);
  AccountKitConfiguration.AccountKitConfigurationBuilder configurationBuilder =
    new AccountKitConfiguration.AccountKitConfigurationBuilder(
      LoginType.EMAIL,
      AccountKitActivity.ResponseType.CODE); // or .ResponseType.TOKEN
  // ... perform additional configuration ...
  intent.putExtra(
    AccountKitActivity.ACCOUNT_KIT_ACTIVITY_CONFIGURATION,
    configurationBuilder.build());
  startActivityForResult(intent, APP_REQUEST_CODE);
}
 com.facebook.accountkit.AccountKit;

public static int APP_REQUEST_CODE = 99;

public void emailLogin(final View view) {
  final Intent intent = new Intent(getActivity(), AccountKitActivity.class);
  AccountKitConfiguration.AccountKitConfigurationBuilder configurationBuilder =
    new AccountKitConfiguration.AccountKitConfigurationBuilder(
      LoginType.EMAIL,
      AccountKitActivity.ResponseType.CODE); // or .ResponseType.TOKEN
  // ... perform additional configuration ...
  intent.putExtra(
    AccountKitActivity.ACCOUNT_KIT_ACTIVITY_CONFIGURATION,
    configurationBuilder.build());
  startActivityForResult(intent, APP_REQUEST_CODE);
}

点击邮件的地址回到应用，需要一个中间者进行重定向。

<activity android:name="com.facebook.accountkit.ui.AccountKitEmailRedirectActivity">
   <intent-filter>
     <action android:name="android.intent.action.VIEW" />
     <category android:name="android.intent.category.DEFAULT" />
     <category android:name="android.intent.category.BROWSABLE" />
     <data android:scheme="@string/ak_login_protocol_scheme" />
  </intent-filter>
</activity>
 android:name="com.facebook.accountkit.ui.AccountKitEmailRedirectActivity">
   <intent-filter>
     <action android:name="android.intent.action.VIEW" />
     <category android:name="android.intent.category.DEFAULT" />
     <category android:name="android.intent.category.BROWSABLE" />
     <data android:scheme="@string/ak_login_protocol_scheme" />
  </intent-filter>
</activity>


// if your Facebook App ID is 1234567, you should use ak1234567
<string name="ak_login_protocol_scheme">akFACEBOOK_APP_ID</string>

<string name="ak_login_protocol_scheme">akFACEBOOK_APP_ID</string>

API的其他功能：
     AccountKitConfigurationBuilder 对象通过提供允许您在运行时改写默认属性的方法。
setInitialAuthState(String initialAuthState) （可选）由开发者生成的一个随机数，用于确认收到的响应与请求匹配。
  setInitialEmail(String initialEmail) （可选）在邮箱登录流程中预填充用户的电子邮箱。
  setDefaultCountryCode(String defaultCountryCode) （可选）设置短信登录流程中默认显示的国家/地区代码。
  setInitialPhoneNumber(PhoneNumber initialPhoneNumber) （可选）在短信登录流程中预填充用户的手机号码。
  setFacebookNotificationsEnabled(boolean facebookNotificationsEnabled) （可选）如果设置此标记，Account Kit 就会向用户提供在短信发送失败后，通过 Facebook 通知接收验证消息的选项，前提是他们的手机号码与 Facebook 帐户关联。关联的手机号码必须是 Facebook 帐户的主要手机号码。
默认：true
setReadPhoneStateEnabled(boolean readPhoneStateEnabled);
setReceiveSMS(boolean receiveSMSEnabled);
setSMSWhitelist(String[] smsWhitelist);
setSMSBlacklist(String[] smsBlacklist);

下面一大块，是自定制Android UI部分的：

开发者SDK：https://developers.facebook.com/docs/accountkit/android/customizing

基本UI:

经典：

半透明：

现代：

高级UI:

为应用添加皮肤：

// constructor without a background image
AccountKitConfiguration.AccountKitConfigurationBuilder configurationBuilder;
UIManager uiManager;

// Skin is CLASSIC, CONTEMPORARY, or TRANSLUCENT
uiManager = new SkinManager(
            Skin <skin>,
            @ColorInt int <primaryColor>);
configurationBuilder.setUIManager(uiManager);
AccountKitConfiguration.AccountKitConfigurationBuilder configurationBuilder;
UIManager uiManager;

// Skin is CLASSIC, CONTEMPORARY, or TRANSLUCENT
uiManager = new SkinManager(
            Skin <skin>,
            @ColorInt int <primaryColor>);
configurationBuilder.setUIManager(uiManager);

// constructor with a background image imageAccountKitConfiguration.AccountKitConfigurationBuilder configurationBuilder;
UIManager uiManager;
// Skin is CLASSIC, CONTEMPORARY, or TRANSLUCENT
// Tint is WHITE or BLACK
// TintIntensity is a value between 55-85%
uiManager = new SkinManager(
            Skin <skin>,
            @ColorInt int <primaryColor>,
            @DrawableRes int <backgroundImage>,
            Tint <tint>,
            double <tintIntensity>);
configurationBuilder.setUIManager(uiManager);
UIManager uiManager;
// Skin is CLASSIC, CONTEMPORARY, or TRANSLUCENT
// Tint is WHITE or BLACK
// TintIntensity is a value between 55-85%
uiManager = new SkinManager(
            Skin <skin>,
            @ColorInt int <primaryColor>,
            @DrawableRes int <backgroundImage>,
            Tint <tint>,
            double <tintIntensity>);
configurationBuilder.setUIManager(uiManager);

Android偏好设置的API:

最多可以为每位用户存储 100 个键/值对。键是 100 个字符以内的字符串，可以包含大小写字母、数字和下划线等字符。值是 1000 个字符以内的字符串。

// Load all preferences for this account:

二，用户注册登录

最总访问口令：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    callbackManager = CallbackManager.Factory.create();

    accessTokenTracker = new AccessTokenTracker() {
        @Override
        protected void onCurrentAccessTokenChanged(
            AccessToken oldAccessToken,
            AccessToken currentAccessToken) {
                // Set the access token using 
                // currentAccessToken when it's loaded or set.
        }
    };
    // If the access token is available already assign it.
    accessToken = AccessToken.getCurrentAccessToken();
}

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

@Override
public void onDestroy() {
    super.onDestroy();
    accessTokenTracker.stopTracking();
}
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    callbackManager = CallbackManager.Factory.create();

    accessTokenTracker = new AccessTokenTracker() {
        @Override
        protected void onCurrentAccessTokenChanged(
            AccessToken oldAccessToken,
            AccessToken currentAccessToken) {
                // Set the access token using 
                // currentAccessToken when it's loaded or set.
        }
    };
    // If the access token is available already assign it.
    accessToken = AccessToken.getCurrentAccessToken();
}

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

@Override
public void onDestroy() {
    super.onDestroy();
    accessTokenTracker.stopTracking();
}

追踪当前个人资料：

@Override

三，Facebook分享

Facebook的分享，有一个前提条件，就是应用必须已经安装，才能够分享。

链接的分享：ShareLinkContent模型进行。

截至 2017 年 4 月 18 日，图谱 API 版本 2.9 及更高版本不再支持下列参数。对于版本 2.8 及更低版本，这些参数将继续有效，直到 2017 年 7 月 17 日。
contentTitle，表示链接中的内容的标题，imageURL，将在帖子中显示的缩略图的网址，内容的 contentDescription，通常为 2-4 个句子

ShareLinkContent content = new ShareLinkContent.Builder()
.setContentUrl(Uri.parse("https://developers.facebook.com"))
.build();

照片分享：小于12MB,客户端在7.0以上，SharePhotoContent模型进行。

Bitmap image = ...
SharePhoto photo = new SharePhoto.Builder()
        .setBitmap(image)
        .build();
SharePhotoContent content = new SharePhotoContent.Builder()
        .addPhoto(photo)
        .build(); image = ...
SharePhoto photo = new SharePhoto.Builder()
        .setBitmap(image)
        .build();
SharePhotoContent content = new SharePhotoContent.Builder()
        .addPhoto(photo)
        .build();

视频分享：小于12MB,ShareVideoContent模型进行

Uri videoFileUri = ...
ShareVideo = new ShareVideo.Builder()
        .setLocalUrl(videoUrl)
        .build();
ShareVideoContent content = new ShareVideoContent.Builder()
        .setVideo(video)
        .build(); videoFileUri = ...
ShareVideo = new ShareVideo.Builder()
        .setLocalUrl(videoUrl)
        .build();
ShareVideoContent content = new ShareVideoContent.Builder()
        .setVideo(video)
        .build();

多媒体分享：

用户需要安装版本 71 或以上的原生 Android 版 Facebook 应用。
照片大小必须小于 12MB。
视频大小必须小于 12MB。
用户每次可以分享最多包含 6 个照片和视频元素的内容。

SharePhoto sharePhoto1 = new SharePhoto.Builder()
    .setBitmap(...)
    .build();
SharePhoto sharePhoto2 = new SharePhoto.Builder()
    .setBitmap(...)
    .build();
ShareVideo shareVideo1 = new ShareVideo.Builder()
    .setLocalUrl(...)
    .build();
ShareVideo shareVideo2 = new ShareVideo.Builder()
    .setLocalUrl(...)
    .build();

ShareContent shareContent = new ShareMediaContent.Builder()
    .addMedium(sharePhoto1)
    .addMedium(sharePhoto2)
    .addMedium(shareVideo1)
    .addMedium(shareVideo2)
    .build();

ShareDialog shareDialog = new ShareDialog(...);
shareDialog.show(shareContent, Mode.AUTOMATIC); sharePhoto1 = new SharePhoto.Builder()
    .setBitmap(...)
    .build();
SharePhoto sharePhoto2 = new SharePhoto.Builder()
    .setBitmap(...)
    .build();
ShareVideo shareVideo1 = new ShareVideo.Builder()
    .setLocalUrl(...)
    .build();
ShareVideo shareVideo2 = new ShareVideo.Builder()
    .setLocalUrl(...)
    .build();

ShareContent shareContent = new ShareMediaContent.Builder()
    .addMedium(sharePhoto1)
    .addMedium(sharePhoto2)
    .addMedium(shareVideo1)
    .addMedium(shareVideo2)
    .build();

ShareDialog shareDialog = new ShareDialog(...);
shareDialog.show(shareContent, Mode.AUTOMATIC);

“赞”按钮
“赞”按钮是用户与好友分享内容的快捷途径。轻触“赞”按钮即可为应用中的内容点“赞”，并将内容分享到 Facebook。

LikeView likeView = (LikeView) findViewById(R.id.like_view);
likeView.setObjectIdAndType(
    "https://www.facebook.com/FacebookDevelopers",
    LikeView.ObjectType.PAGE); likeView = (LikeView) findViewById(R.id.like_view);
likeView.setObjectIdAndType(
    "https://www.facebook.com/FacebookDevelopers",
    LikeView.ObjectType.PAGE);

“分享”按钮
“分享”按钮将调用分享对话框。要添加“分享”按钮

ShareButton shareButton = (ShareButton)findViewById(R.id.fb_share_button);
shareButton.setShareContent(content); shareButton = (ShareButton)findViewById(R.id.fb_share_button);
shareButton.setShareContent(content);

分享对话框
分享对话框会切换到原生 Android 版 Facebook 应用，并在发布帖子后将控制权交还您的应用。如果未安装 Facebook 应用，会自动回退到网页对话框。

     callbackManager = CallbackManager.Factory.create();
        shareDialog = new ShareDialog(this);
        // this part is optional
        shareDialog.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() { ... });
= CallbackManager.Factory.create();
        shareDialog = new ShareDialog(this);
        // this part is optional
        shareDialog.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() { ... });

if (ShareDialog.canShow(ShareLinkContent.class)) {
    ShareLinkContent linkContent = new ShareLinkContent.Builder()
            .setContentUrl(Uri.parse("http://developers.facebook.com/android"))
            .build();
    shareDialog.show(linkContent);
} (ShareDialog.canShow(ShareLinkContent.class)) {
    ShareLinkContent linkContent = new ShareLinkContent.Builder()
            .setContentUrl(Uri.parse("http://developers.facebook.com/android"))
            .build();
    shareDialog.show(linkContent);
}

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