无法使用Facebook API获取位置和电子邮件

问题是您没有要求权限：

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

但是，您使用的是较旧的Facebook
SDK，而最新的SDK是4.0。+。下面，我将基于最新的API为您提供Facebook登录的完整示例代码。请记住，

developers.facebook

public class LoginActivity extends ActionBarActivity{@Overrideprotected void onActivityResult(int requestCode, int responseCode, Intent data){    super.onActivityResult(requestCode, responseCode, data);    callbackManager.onActivityResult(requestCode, responseCode, data);}@Overrideprotected 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 pre      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());        }    });  }}

如果要使用

Fragment

ActionBarActivity

loginButton.setFragment(this);

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"/>

您还将需要向您的应用程序添加一个 哈希键 。这是使用代码执行此操作的方法：

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.enpreToString(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){}

在将您的哈希键打印出来之后，您可以将其复制粘贴到您

facebook.developer

在grandle，你应该添加

jcenter

repositories

compile'com.facebook.android:facebook-android-sdk:4.0.0'

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()      }}

还有另一个文件：

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

编辑：

为了跟踪用户的位置，您将需要GPS跟踪器，类似这样。

"user_location"

lon,lat

List<String>permissionNeeds=Arrays.asList("user_photos", "email", "user_birthday","public_profile");
