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 

        图一

        

       图二

             

       图三

      

      图四

        

     图五

      

 

 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

         图一

         

      图二

        

      图三

       

         

 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

              <!-- facebook 登录 key-->

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

       5.4 在 AndroidManifest.xml 中          

 
<meta-data
            android: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

1
2
3
4
5
6
7
<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 accessToken
 4      */
 5     public void getLoginInfo( AccessToken accessToken ){
 6         GraphRequest request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() {
 7             @Override
 8             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

         

                      

6、对facebookSDk 进行二次封装
