问题描述

我无法摆脱来自Facebook SDK V4的 ProfileTracker 功能的基本个人资料信息。我怎样才能得到所有的信息？

我目前在成功登录和歌厅的accessToken 和用户ID 。

code：

 公共类HelloFacebookSampleActivity扩展FragmentActivity {    LoginButton loginButton;    CallbackManager callbackManager;
    私人字符串fbUserID;
    私人字符串fbProfileName;
    私人字符串fbAuthToken;    私人AccessTokenTracker accessTokenTracker;

        loginButton =（LoginButton）findViewById（R.id.login_button）;
        loginButton.setReadPermissions（user_friends，电子邮件，user_birthday，user_likes）;        profileTracker =新ProfileTracker（）{
            @覆盖
            保护无效onCurrentProfileChanged（

            }
        };
        accessTokenTracker =新AccessTokenTracker（）{

                fbUserID = currentAccessToken.getUserId（）;                Log.d（TAG，用户ID：+ fbUserID）;
                Log.d（TAG，访问令牌+ fbAuthToken）;
                //确保我们的个人资料是最新的
                Profile.fetchProfileForCurrentAccessToken（）;
            }
        };
        //回调注册
        loginButton.registerCallback（callbackManager，新FacebookCallback＆LT; LoginResult＆GT;（）{
            @覆盖
            公共无效的onSuccess（LoginResult loginResult）{

            公共无效onerror的（FacebookException除外）{
                //应用code

            }
        }）;
    }
    @覆盖
    公共无效的onDestroy（）{
        super.onDestroy（）;        accessTokenTracker.stopTracking（）;
        profileTracker.stopTracking（）;
    }
    @覆盖
    保护无效的onActivityResult（INT申请code，INT结果code，意图数据）{
        super.onActivityResult（要求code，结果code，数据）;
        callbackManager.onActivityResult（要求code，结果code，数据）;
    }

错误：

 显示java.lang.NullPointerException：尝试在调用接口方法无效com.android.okhttp.internal.http.Transport.writeRequestHeaders（com.android.okhttp.Request）'空对象引用
        在com.android.okhttp.internal.http.HttpEngine.readResponse（HttpEngine.java:611）

        在com.android.okhttp.internal.http.HttpsURLConnectionImpl.getResponse$c$c(HttpsURLConnectionImpl.java:25)

解决方案

要完成这项工作，有3件code，你需要纳入你的code：

创建 profileTracker ：

  mProfileTracker =新ProfileTracker（）{
    @覆盖
    保护无效onCurrentProfileChanged（PROFILE资料，档案PROFILE2）{
        的updateUI（）; //这是第三件code的我将在下面讨论
    }
};

请确保您启动 profileTracker 在的onCreate 按照Facebook的DOC：
```
  mProfileTracker.startTracking（）;
 
```

获取配置文件信息：

 私人无效的updateUI（）{     布尔enableButtons = AccessToken.getCurrentAccessToken（）！= NULL;简介配置= Profile.getCurrentProfile（）;
如果（配置文件== NULL）{
    Log.e（档案，空）;
}
如果（enableButtons＆安培;＆安培;型材！= NULL）{
    Log.e（访问令牌，AccessToken.getCurrentAccessToken（）的toString（））;
    Log.e（TabSocial，profile.getName（））;
}

}

我花这个凌晨3个小时的测试出HelloFacebookSample应用之后发现这一点。

I am unable to get basic profile info from the ProfileTracker function from Facebook SDK v4. How can I get all the info?

I am currently successfully logging in and geting accesstoken and user-id.

Code:

public class HelloFacebookSampleActivity extends FragmentActivity {



    LoginButton loginButton ;

    CallbackManager callbackManager;


    private String fbUserID;
    private String fbProfileName;
    private String fbAuthToken;

    private AccessTokenTracker accessTokenTracker;


    private ProfileTracker profileTracker;


    private static final String TAG = "FacebookLogin";

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



        FacebookSdk.sdkInitialize(getApplicationContext());

        callbackManager = CallbackManager.Factory.create();

        setContentView(R.layout.test);
        loginButton = (LoginButton) findViewById(R.id.login_button);
        loginButton.setReadPermissions("user_friends,email,user_birthday,user_likes");



        profileTracker = new ProfileTracker() {
            @Override
            protected void onCurrentProfileChanged(
                    Profile oldProfile,
                    Profile currentProfile) {


                fbProfileName = currentProfile.getName();

                Toast.makeText(getBaseContext(),"profile",Toast.LENGTH_LONG).show();


                Log.d(TAG, "FirstName: " + currentProfile.getFirstName() );

                Log.d(TAG, "LastName: " + currentProfile.getLastName() );

                Log.d(TAG, " MiddleName: " + currentProfile.getMiddleName() );

                Log.d(TAG, "LinkUri: " + currentProfile.getLinkUri() );

                Log.d(TAG, "ProfilePictureUri: " + currentProfile.getProfilePictureUri(250,250) );




            }
        };


        accessTokenTracker = new AccessTokenTracker() {
            @Override
            protected void onCurrentAccessTokenChanged(
                    AccessToken oldAccessToken,
                    AccessToken currentAccessToken) {
                fbAuthToken = currentAccessToken.getToken();
                fbUserID = currentAccessToken.getUserId();



                Log.d(TAG, "User id: " + fbUserID);
                Log.d(TAG, "Access token is: " + fbAuthToken);


                // Ensure that our profile is up to date
                Profile.fetchProfileForCurrentAccessToken();
            }
        };




        // Callback registration
        loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {




            }

            @Override
            public void onCancel() {
                // App code

                Toast.makeText(getBaseContext(),"cancel",Toast.LENGTH_LONG).show();
            }

            @Override
            public void onError(FacebookException exception) {
                // App code
                Toast.makeText(getBaseContext(),"er",Toast.LENGTH_LONG).show();
            }
        });










    }




    @Override
    public void onDestroy() {
        super.onDestroy();

        accessTokenTracker.stopTracking();
        profileTracker.stopTracking();
    }


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

Error:

java.lang.NullPointerException: Attempt to invoke interface method 'void com.android.okhttp.internal.http.Transport.writeRequestHeaders(com.android.okhttp.Request)' on a null object reference
        at com.android.okhttp.internal.http.HttpEngine.readResponse(HttpEngine.java:611)

解决方案

To make this work, there are 3 parts of code that you need to incorporate into your code:

Create your profileTracker:

mProfileTracker = new ProfileTracker() {
    @Override
    protected void onCurrentProfileChanged(Profile profile, Profile profile2) {
        updateUI(); //this is the third piece of code I will discuss below
    }
};

Make sure you start your profileTracker in onCreate as per Facebook's doc:
```
mProfileTracker.startTracking();
```

Get the profile information:

private void updateUI(){

     boolean enableButtons = AccessToken.getCurrentAccessToken() != null;

Profile profile = Profile.getCurrentProfile();
if (profile == null) {
    Log.e("Profile", "null");
}
if (enableButtons && profile != null) {
    Log.e("Access Token",AccessToken.getCurrentAccessToken().toString());
    Log.e("TabSocial", profile.getName());
}

}

I discovered this after spending 3 hours this morning testing out the HelloFacebookSample app.
