Android 應用程式整合FaceBook 登入及二次封裝

標籤：

1、首先在Facebook 開發人員平台註冊一個帳號

        https://developers.facebook.com/

      開發人員後台  https://developers.facebook.com/apps

2、建立帳號並且獲得 APP ID

 3、擷取app簽名的Key Hashes 值（兩種方式）         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      * 注意啟動並執行時候，app需要正式的簽名18      * @param context19      * @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 命令列的方式擷取 Key hash 值            3.2.1 ：首選保證你的電腦上有 openSSl 的庫檔案

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

                    

          3.2.2 ：解壓下載的檔案         

                   

 

        3.2.3：cmd 命令列模式定位到 openssl 的 bin目錄下

                  

       3.2.4：執行命令

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

                注意： 1、這裡的 yiba 代表app簽名的別名，也就是 alias 

                          2、C:\work\Key.jks 代表簽名的路徑，需要換成你簽名的路徑

                       

                               

       

       3.2.5 如果你的電腦上沒有下載 openssl 那麼你執行下面的代碼會出現

                     

 

 4、設定應用的基本配置

         圖一

         

      圖二

        

      圖三

       

         

 5、App開始整合 FacebookSDk        5.1 在項目的 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 在應用的 Application 裡面初始化SDK

            //facebook登入初始化

      FacebookSdk.sdkInitialize( getApplicationContext() );

       5.3 在value檔案夾下 strings.xml 中

              <!-- facebook 登入 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 在布局檔案中定義登入按鈕

1234567

<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 在代碼中實現 

 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  * 登入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     @Override29     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             @Override43             public void onSuccess(LoginResult loginResult) {44                 Toast.makeText(LoginLoginActivity.this, "facebook登入成功了", Toast.LENGTH_SHORT).show();45                 log("facebook登入成功了" + loginResult.getAccessToken());
                   //擷取登入資訊
                   getLoginInfo( loginResult.getAccessToken() ) ;46             }47 48             @Override49             public void onCancel() {50                 Toast.makeText(LoginLoginActivity.this, "facebook登入取消了", Toast.LENGTH_SHORT).show();51                 log("facebook登入取消了");52             }53 54             @Override55             public void onError(FacebookException error) {56                 Toast.makeText(LoginLoginActivity.this, "facebook登入失敗了", Toast.LENGTH_SHORT).show();57                 log("facebook登入失敗了");58             }59         });60         61     }62     63     @Override64     protected void onActivityResult(int requestCode, int resultCode, Intent data) {65         super.onActivityResult(requestCode, resultCode, data);66 67         //facebook回調68         callbackManager.onActivityResult( requestCode , resultCode ,data ) ;69     }70 }

 

 

 

 1 /** 2      * 擷取登入資訊 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:156545522156511                     String name = object.optString( "name" ) ;  //比如：Zhang San12                     String gender = object.optString("gender") ;  //性別：比如 male （男）  female （女）13                     String emali = object.optString("email") ;  //郵箱：比如：[email protected]14 15                     //擷取帳戶圖片16                     JSONObject object_pic = object.optJSONObject( "picture" ) ;17                     JSONObject object_data = object_pic.optJSONObject( "data" ) ;18                     String photo = object_data.optString( "url" )  ;19 20                     //擷取地區資訊21                     String locale = object.optString( "locale" ) ;   //zh_CN 代表中文簡體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 企業帳號需要注意的事項，把發布按鈕開啟

         

                      

6、對facebookSDk 進行二次封裝         

  1 package com.pegasus.map.presentation.utils;  2   3 import android.app.Activity;  4 import android.content.DialogInterface;  5 import android.os.Bundle;  6 import android.support.v7.app.AlertDialog;

14 import com.facebook.GraphResponse; 15 import com.facebook.Profile; 16 import com.facebook.login.LoginManager; 17 import com.facebook.login.LoginResult; 18  19 import org.json.JSONObject; 20  21 import java.util.Arrays;
