Android 应用程序集成FaceBook 登录及二次封装

1、首先在Facebook 开发者平台注册一个账号

https://developers.facebook.com/

开发者后台 https://developers.facebook.com/apps

2、创建账号并且获得 APP ID

3、获取app签名的Key Hashes 值（两种方式）

3.1方法1：

 1 package com.pegasus.map.presentation.utils;2 import android.content.Context;3 import android.content.pm.PackageInfo;4 import android.content.pm.PackageManager;5 import android.content.pm.Signature;6 import android.util.Base64;7 import android.widget.Toast;8 import java.security.MessageDigest;9 import java.security.NoSuchAlgorithmException;
10
11 /**
12  * Created by ${zyj} on 2016/3/29.
13  */
14 public class KeyHash {
15
16     /**
17      * 注意运行的时候，app需要正式的签名
18      * @param context
19      * @param packageName  app的包名
20      */
21     public static void getKeyHash( Context context , String packageName ){
22         try {
23             PackageInfo info = null;
24             info = context.getPackageManager().getPackageInfo( packageName , PackageManager.GET_SIGNATURES );
25             for ( Signature signature : info.signatures ) {
26                 MessageDigest messageDigest = null;
27                 messageDigest = MessageDigest.getInstance("SHA");
28                 messageDigest.update(signature.toByteArray());
29                 String hs = Base64.encodeToString(messageDigest.digest(), Base64.DEFAULT) ;
30                 Toast.makeText(context, "" + hs , Toast.LENGTH_SHORT).show();
31             }
32         } catch (PackageManager.NameNotFoundException e) {
33             e.printStackTrace();
34         } catch (NoSuchAlgorithmException e) {
35             e.printStackTrace();
36         }
37     }
38 }

3.2 命令行的方式获取 Key hash 值

3.2.1 ：首选保证你的电脑上有 openSSl 的库文件

下载 http://gnuwin32.sourceforge.net/packages/openssl.htm

3.2.2 ：解压下载的文件

3.2.3：cmd 命令行模式定位到 openssl 的 bin目录下

3.2.4：执行命令

keytool -exportcert -alias yiba -keystore C:\work\Key.jks | openssl sha1 -binary | openssl base64

注意： 1、这里的 yiba 代表app签名的别名，也就是 alias

2、C:\work\Key.jks 代表签名的路径，需要换成你签名的路径

3.2.5 如果你的电脑上没有下载 openssl 那么你执行下面的代码会出现

4、设置应用的基本配置

5、App开始集成 FacebookSDk

5.1 在项目的 build.gradle 添加

compile 'com.facebook.android:facebook-android-sdk:4.10.1'

查看最新的版本： http://search.maven.org/#search%7Cga%7C1%7Ccom.facebook.android

5.2 在应用的 Application 里面初始化SDK

//facebook登录初始化

      FacebookSdk.sdkInitialize( getApplicationContext() );

5.3 在value文件夹下 strings.xml 中

      <string name="facebook_app_id">1001702146573854</string>

5.4 在 AndroidManifest.xml 中

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

<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"    ></activity>

5.5 在布局文件中定义登录按钮

<com.facebook.login.widget.LoginButton

android:id="@+id/facebook_bt"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:text="facebook login"

>

</com.facebook.login.widget.LoginButton>

5.6 在代码中实现

 1 package com.pegasus.map.presentation.ui.activity;2 import android.content.Intent;3 import android.os.Bundle;4 import android.widget.Toast;5 import com.facebook.CallbackManager;6 import com.facebook.FacebookCallback;7 import com.facebook.FacebookException;8 import com.facebook.login.LoginResult;9 import com.facebook.login.widget.LoginButton;
10 import com.pegasus.map.R;
11 import com.pegasus.map.presentation.ui.base.BaseActivity;
12 import butterknife.Bind;
13 import butterknife.ButterKnife;
14
15
16 /**
17  * Created by ${zyj} on 2016/3/24.
18  * 登录
19  */
20
21 public class LoginLoginActivity extends BaseActivity {
22
23     @Bind(R.id.facebook_bt)
24     public LoginButton facebook_bt;
25
26     private CallbackManager callbackManager ;
27
28     @Override
29     protected void onCreate(Bundle savedInstanceState) {
30         super.onCreate(savedInstanceState);
31         setContentView(R.layout.activity_login);
32
33         ButterKnife.bind(this);
34         callbackManager = CallbackManager.Factory.create() ;
35
36         init();
37     }
38
39     private void init() {
40
41         facebook_bt.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
42             @Override
43             public void onSuccess(LoginResult loginResult) {
44                 Toast.makeText(LoginLoginActivity.this, "facebook登录成功了", Toast.LENGTH_SHORT).show();
45                 log("facebook登录成功了" + loginResult.getAccessToken());                   //获取登录信息                   getLoginInfo( loginResult.getAccessToken() ) ;
46             }
47
48             @Override
49             public void onCancel() {
50                 Toast.makeText(LoginLoginActivity.this, "facebook登录取消了", Toast.LENGTH_SHORT).show();
51                 log("facebook登录取消了");
52             }
53
54             @Override
55             public void onError(FacebookException error) {
56                 Toast.makeText(LoginLoginActivity.this, "facebook登录失败了", Toast.LENGTH_SHORT).show();
57                 log("facebook登录失败了");
58             }
59         });
60
61     }
62
63     @Override
64     protected void onActivityResult(int requestCode, int resultCode, Intent data) {
65         super.onActivityResult(requestCode, resultCode, data);
66
67         //facebook回调
68         callbackManager.onActivityResult( requestCode , resultCode ,data ) ;
69     }
70 }

 1 /**2      * 获取登录信息3      * @param accessToken4      */5     public void getLoginInfo( AccessToken accessToken ){6         GraphRequest request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() {7             @Override8             public void onCompleted(JSONObject object, GraphResponse response) {9                 if (object != null) {
10                     String id = object.optString( "id" ) ;   //比如:1565455221565
11                     String name = object.optString( "name" ) ;  //比如：Zhang San
12                     String gender = object.optString("gender") ;  //性别：比如 male （男）  female （女）
13                     String emali = object.optString("email") ;  //邮箱：比如：56236545@qq.com
14
15                     //获取用户头像
16                     JSONObject object_pic = object.optJSONObject( "picture" ) ;
17                     JSONObject object_data = object_pic.optJSONObject( "data" ) ;
18                     String photo = object_data.optString( "url" )  ;
19
20                     //获取地域信息
21                     String locale = object.optString( "locale" ) ;   //zh_CN 代表中文简体
22
23                     Toast.makeText( activity , "" + object.toString() , Toast.LENGTH_SHORT).show();
24                 }
25             }
26         }) ;
27
28         Bundle parameters = new Bundle();
29         parameters.putString("fields", "id,name,link,gender,birthday,email,picture,locale,updated_time,timezone,age_range,first_name,last_name");
30         request.setParameters(parameters);
31         request.executeAsync() ;
32     }

5.7 企业账号需要注意的事项，把发布按钮打开
