使用Facebook的API无法获取位置和电子邮件 [英] Can't get location and email using Facebook API

问题描述

在我的Andr​​oid应用我开发了这个code登录我的帐户，并得到这样的名称，位置和电子邮件用户属性。现在的问题是我能得到这个名字，但我不能让电子邮件和位置。当我想我的code，而不尝试捕捉应用美眉和我的日志点的getProperty（电子邮件）和的getLocation（）。当我使用的尝试。该应用程序的工作，但没有任何邮件或位置。

解决方案

问题是，你有没有问权限：

  authButton.setReadPermissions（Arrays.asList（user_likes，user_status，电子邮件，user_birthday））;
 

不过，您使用的是旧的Facebook SDK，而最新的SDK是4.0 + 。下面，我会给你一个完整的示例code的Facebook登录，基于最新的API。请记住，你首先要添加您的应用程序 developers.facebook 作为的documentation 提到了。

如果你想使用片段，而不是 ActionBarActivity 时，只需添加 loginButton。 setFragment（本）; 右后您的许可行

为了追踪用户的位置，你需要一个GPS追踪器，像<一个href="http://stackoverflow.com/questions/17519198/how-to-get-the-current-location-latitude-and-longitude-in-android">this. user_location权限不会返回经度，纬度，但是的页对象，我想这是不是你想要的。因此，您的权限应该是名单，其中，字符串＆GT; permissionNeeds = Arrays.asList（user_photos，电子邮件，user_birthday，public_profile）; ，现在你应该可以检索用户的电子邮件

In my Android application I developed this code to login with my account and get user property like name, location and email. The problem is I can get the name, but I can't get the email and the location. When I tried my code without try catch the application crush and my log point in getproperty("email") and getlocation(). When I use the try. The application work but there is no email or location.

解决方案

The issue is that you have not asked for permissions:

authButton.setReadPermissions(Arrays.asList("user_likes", "user_status","email","user_birthday"));

However, you are using an older Facebook SDK, while the newest SDK is 4.0.+. Below, I will give you a full sample code for Facebook login, based on the newest API. Keep in mind that you first have to add your application in developers.facebook as the documentation mentions out.

public class LoginActivity extends ActionBarActivity{

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

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(this.getApplicationContext());
    setContentView(R.layout.activity_login);
    callbackManager = CallbackManager.Factory.create();
    loginButton = (LoginButton) findViewById(R.id.loginFaceBook_button);
    List<String> permissionNeeds = Arrays.asList("user_photos", "email", "user_birthday", "public_profile");
    loginButton.setReadPermissions(permissionNeeds);

    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>()
    {
        @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)
                        {
                            // Application code
                            Log.v("LoginActivity", 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");
                                System.out.println(id + ", " + name + ", " + email + ", " + gender + ", " + birthday);
                            }
                            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()
        {
            System.out.println("onCancel");
        }

        @Override
        public void onError(FacebookException exception)
        {
            System.out.println("onError");
            Log.v("LoginActivity", exception.getCause().toString());
        }
    });
  }
}

If you want to use Fragment instead of ActionBarActivity, the just add loginButton.setFragment(this); right after your permission line.

manifest.xml:

<uses-permission android:name="android.permission.INTERNET"/> 
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<application
    <!-- your other attrs..-->
    <meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/app_id"/> <!-- Get this one from developers.facebook -->
    <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"/>

You will need to add to your application a hash key too. Here is a way to do this with code:

try
{
    //paste Your package name at the first parameter
    PackageInfo info = getPackageManager().getPackageInfo("PUT_YOUR_PACKAGE_NAME_HERE",
            PackageManager.GET_SIGNATURES);
    for (android.content.pm.Signature signature : info.signatures)
    {
        MessageDigest md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        String sign = Base64.encodeToString(md.digest(), Base64.DEFAULT);
        Log.e("MY KEY HASH:", sign);
        Toast.makeText(getApplicationContext(),sign,     Toast.LENGTH_LONG).show();
    }
}
catch (PackageManager.NameNotFoundException e)
{
}
catch (NoSuchAlgorithmException e)
{
}

After it prints you out the hash key, you copy paste it to your facebook.developer account, where your project is located.

In grandle, you should add jcenter in repositories and also add compile 'com.facebook.android:facebook-android-sdk:4.0.0' in dependecies.

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:1.1.0'
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}
allprojects 
{
repositories {
    jcenter()
    /*more project attrs..*/
  }
}

And the other grandle file:

apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "YOUR_PACKAGE_NAME"
    minSdkVersion 14
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.facebook.android:facebook-android-sdk:4.0.0'
}

Edit:

In order to track the user's location, you will need a GPS Tracker, something like this. "user_location" permission does not return a lon, lat, but a Page object, which I think is not what you want.
