国外社交网站的授权登录（FaceBook，Twitter，Linkedin，Google+）

开发需要在国外上线的项目，集成了几种国外常用社交网站的授权登录（FaceBook，Twitter，Linkedin，Google+）。挖到的一些坑与解决办法。当然途中肯定都需要科学上网的方式进行...其实umeng集成了Twitter和FB，但是Twitter莫名不能成功，所以都自己搞一下。

Google+， Linkedin的集成来自同事

Google+授权三方登录

sdk 需要下载google_play_services,在as中按照下面的方式进行配置
获取google配置文件，需要在google增加个人应用，并且根据包名和sah1码生成配置文件
戳这里
获取配置文件后，将google-services.json放到app目录下
在项目给的gradle文件的dependncies节点下增加
classpath ‘com.google.gms:google-services:2.0.0-alpha6’
在app 的gradle中增加
apply plugin: ‘com.google.gms.google-services’
在app的gradle中增加
dependencies { compile ‘com.google.android.gms:play-services-auth:9.2.1’ }
在google登录的onCreate的方法中增加

// Configure sign-in to request the user's ID, email address, and basic
// profile. ID and basic profile are included in DEFAULT_SIGN_IN.
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) 
     .requestEmail()
     .build();
// Build a GoogleApiClient with access to the Google Sign-In API and the
// options specified by gso.
mGoogleApiClient = new GoogleApiClient.Builder(this) 
    .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)          
    .addApi(Auth.GOOGLE_SIGN_IN_API, gso) 
    .build();

在对应的xml文件中增加

在activity可以设置signinbutton的样式

// Customize sign-in button. The sign-in button can be displayed in
// multiple sizes and color schemes. It can also be contextually
// rendered based on the requested scopes. For example. a red button may
// be displayed when Google+ scopes are requested, but a white button
// may be displayed when only basic profile is requested. Try adding the
// Scopes.PLUS_LOGIN scope to the GoogleSignInOptions to see the
// difference.SignInButton signInButton = (SignInButton) findViewById(R.id.sign_in_button);
signInButton.setSize(SignInButton.SIZE_STANDARD);
signInButton.setScopes(gso.getScopeArray());
signInButton.setOnClickListener(this);

在onClick方法中

@Override
public void onClick(View v) { 
  switch (v.getId()) { 
    case R.id.sign_in_button: 
      Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);       
      startActivityForResult(signInIntent, RC_SIGN_IN);
       break; // ... 
    }
}

在onActivityResult方法中设置如下

@Override
  public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
     if (requestCode == RC_SIGN_IN) { 
      GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data); 
      handleSignInResult(result); 
    }
}
private void handleSignInResult(GoogleSignInResult result) { 
  Log.d(TAG, "handleSignInResult:" + result.isSuccess()); 
  if (result.isSuccess()) { 
    // Signed in successfully, show authenticated UI. 
    GoogleSignInAccount acct = result.getSignInAccount();     
    mStatusTextView.setText(getString(R.string.signed_in_fmt, acct.getDisplayName())); 
    updateUI(true); 
  } else { 
    // Signed out, show unauthenticated UI. 
    updateUI(false); 
    }
}

Google开发文档
注意google play服务版本不兼容或者版本太低引起崩溃

Linkedin授权三方登录

需要在linkedin开发者那里注册应用。
戳这里
添加后，需要填写应用包名和package Hash码

具体方式可自行百度或者参考这个
下载linkedin的sdk并以module的方式集成到自己的项目中
获取手机端的授权详情

public class MainActivity extends Activity {    
    @Override    
    protected void onCreate(Bundle savedInstanceState) {        
       // Store a reference to the current activity         
      final Activity thisActivity = this;        
      LISessionManager.getInstance(getApplicationContext()).init(thisActivity, buildScope(), new AuthListener() {            
        @Override            
        public void onAuthSuccess() {                
          // Authentication was successful.  You can now do                
          // other calls with the SDK.            
        }            
        @Override            
        public void onAuthError(LIAuthError error) {                
          // Handle authentication errors            
        }        
      }, true);    
     }
}
    // Build the list of member permissions our LinkedIn session requires
    private static Scope buildScope() {    
      return Scope.build(Scope.R_BASICPROFILE, Scope.W_SHARE);
    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {    
      // Add this line to your existing onActivityResult() method      
      LISessionManager.getInstance(getApplicationContext()).onActivityResult(this, requestCode,   resultCode, data);
    }
}

获取授权成功后，获取用户信息 url：
获取全部信息 https://api.linkedin.com/v1/people/~
获取指定信息 https://api.linkedin.com/v1/people/~:(firstName,lastName,id,picture-url)?format=json
或者戳Linkedin开发文档

String url ="https://api.linkedin.com/v1/people/~:(firstName,lastName,id,picture-url)?format=json"; 
APIHelper apiHelper = APIHelper.getInstance(getApplicationContext()); apiHelper.getRequest(getApplicationContext(), url, new ApiListener() { 
    @Override 
    public void onApiSuccess(ApiResponse apiResponse) { 
      // Success! 
      LogUtils.e(TAG, "apiResponse" + apiResponse.toString()); 
    } 
    @Override 
    public void onApiError(LIApiError liApiError) { 
      // Error making GET request! 
      LogUtils.e(TAG, " Error making GET request!"); 
    }

Twitter授权三方登录

创建Twitter开发者账号
创建Twitter账号
Twitter开发者平台
这里的需要使用的美国的手机号请自行解决 0.0
记得设置app的callback url，不然无法调起网页版的授权界面
集成的准备工作
有两种集成方式，twitter4j或者官方的Fabric（可自行查看官方文档）
据说twitter4j有事不稳定？最后选了Fabric（要在AS中使用）

安装Fabric插件

然后就注册登录，选择自己的项目，安装

它就会自动在你代码中加入必要代码

因为文档中没看到要安装插件的相关说明，所以按照文档进行集成，
运行后报找不到crashlytics的错时才将Fabric集成进来。
具体能帮助增加哪部分代码自行体会吧~

集成授权登录
自带的button按钮

设置callback以及回调

loginButton.setCallback(new Callback() {    
    @Override    
    public void success(Result result) {        
      String name = result.data.getUserName();        
      long userId = result.data.getUserId();        
      long id = result.data.getId();        
      TwitterAuthToken token = result.data.getAuthToken();        
      String secret = token.secret;        
      String strToken = token.token;        
    }    
    @Override    
    public void failure(TwitterException exception) {        
      Log.d("TwitterKit", "Login with Twitter failure", exception);          
    }
  });

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

这里基本就是结束了

遇到的一个坑
官方文档中

      TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);
      Fabric.with(this, new Twitter(authConfig));

部分在Activity中进行的初始化。但是一直无法调起Twitter，放在application中初始化才可以。

FaceBook授权三方登录

添加FB授权应用

填写应用名称后就生成了App ID和App Secret
选settings，填写包名，Key Hashes（自行百度生成方式），打开Single Sign On，基本就完成准备工作了
添加配置
AndroidManifast.xml中

一定要注意，这个value="@string/application_id" 不要将id直接放进来，不然会出现id错误...

在build.gradle的dependencies引入facebook包

compile 'com.facebook.android:facebook-android-sdk:4.6.0'

代码加入，用的原生的按钮

初始化

FacebookSdk.sdkInitialize(activity.getApplicationContext());
CallbackManager callbackManager = CallbackManager.Factory.create();

必须放在setContentView前初始化，不然报错

List permissionNeeds = Arrays.asList("user_photos", "email", "user_birthday", "public_profile");
loginButton.setReadPermissions(permissionNeeds);
loginButton.registerCallback(callbackManager, new FacebookCallback() {    
    @Override    
    public void onSuccess(LoginResult loginResult) {        
      System.out.println("onSuccess");        
      GraphRequest request = GraphRequest.newMeRequest                (loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {                    
        @Override                    
        public void onCompleted(JSONObject object, GraphResponse response) {                        
          LoginManager.getInstance().logOut();                        
          // Application code                        
          LogUtils.e(TAG, response.toString());                        
          //System.out.println("Check: " + response.toString());                        
          try {                            
            String id = object.getString("id");                            
            String name = object.getString("name");                            
            String email = object.getString("email");                            
            String gender = object.getString("gender");                            
            String birthday = object.getString("birthday");                            
            LogUtils.e(TAG, id + ", " + name + ", " + email + ", " + gender + ", " + birthday);                            
            if (listener != null) {                                
              listener.onSucceed(new SocialLoginBean(id, "", name, SocialLoginBean.TYPE_FACEBOOK));                            
            }                        
          } catch (JSONException e) {                            
            e.printStackTrace();                           
          }                    
        }                
      });        
      Bundle parameters = new Bundle();        
      parameters.putString("fields", "id,name,email,gender, birthday");        
      request.setParameters(parameters);        
      request.executeAsync();    
    }    
    @Override    
    public void onCancel() {        
      if (listener != null) {            
        listener.onError(UIUtils.getString(R.string.toast_login_cancel));        
      }    
    }    
    @Override    
    public void onError(FacebookException exception) {        
      if (listener != null) {            
        listener.onError(UIUtils.getString(R.string.toast_login_error));        
      }    
    }
});
