通过android中的fb登录后无法获取emailId

我正在使用最近的Fb SDK。 我在Android Studio中进行fb集成。 我已经完成了fb docs的所有步骤。 但是在通过fb成功登录后我没有收到电子邮件ID。

这是我的MainActivity.java

package com.example.myapp; import android.app.Activity; import android.content.Intent; import android.support.v4.app.Fragment; import android.os.Bundle; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.Button; import android.widget.TextView; import android.widget.Toast; import com.facebook.AccessToken; import com.facebook.AccessTokenTracker; import com.facebook.CallbackManager; import com.facebook.FacebookCallback; import com.facebook.FacebookException; import com.facebook.FacebookSdk; import com.facebook.GraphRequest; import com.facebook.GraphResponse; import com.facebook.Profile; import com.facebook.ProfileTracker; import com.facebook.login.LoginResult; import com.facebook.login.widget.LoginButton; import org.json.JSONArray; import org.json.JSONException; import org.json.JSONObject; import java.net.MalformedURLException; import java.net.URL; import java.util.Arrays; import java.util.List; public class MainActivity extends Activity { private CallbackManager callbackManager; Button fb; private AccessTokenTracker accessTokenTracker; private ProfileTracker profileTracker; LoginButton loginButton; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); FacebookSdk.sdkInitialize(this.getApplicationContext()); setContentView(R.layout.activity_main); // fb = (Button)findViewById(R.id.button); callbackManager = CallbackManager.Factory.create(); fb = (Button) findViewById(R.id.fb); loginButton = (LoginButton) findViewById(R.id.login_button); List permissionNeeds = Arrays.asList("user_photos", "email", "user_birthday", "public_profile", "AccessToken"); loginButton.registerCallback(callbackManager, new FacebookCallback  () {@Override public void onSuccess(LoginResult loginResult) { System.out.println("onSuccess"); String accessToken = loginResult.getAccessToken() .getToken(); Log.i("accessToken", accessToken); GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(),new GraphRequest.GraphJSONObjectCallback(){ @Override public void onCompleted(JSONObject object, GraphResponse response) { Log.i("LoginActivity", object.toString()); Toast.makeText(getApplicationContext(), object.toString(),Toast.LENGTH_LONG).show(); try { String id = object.getString("id").toString(); String name = object.getString("name"); String email = object.getString("email"); String gender = object.getString("gender"); String birthday = object.getString("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()); } }); } public void onClick(View v) { if (v == fb) { loginButton.performClick(); } } @Override protected void onActivityResult(int requestCode, int responseCode, Intent data) { super.onActivityResult(requestCode, responseCode, data); callbackManager.onActivityResult(requestCode, responseCode, data); } } 

这是My activity_main.xml

这是我的Mainifest

这是我的build.gradle模块：app

 apply plugin: 'com.android.application' android { compileSdkVersion 23 buildToolsVersion "23.0.2" defaultConfig { applicationId "com.example.myapp" minSdkVersion 15 targetSdkVersion 23 versionCode 1 versionName "1.0" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } repositories { mavenCentral() } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:23.1.1' compile 'com.facebook.android:facebook-android-sdk:4.7.0' } 

当我得到回应时

 12-03 21:28:10.452 8572-8572/? I/LoginActivity: {"id":"983511081738745","name":"Subhankar Chakraborty","gender":"male"} 

如果有任何关于我的应用程序的问题，请告诉我。

尝试这个它对我有用希望所以它也适合你，我建立在android studio.and sdk4.7.0

MainActivity.class

 import android.app.Activity; import android.content.Intent; import android.support.v4.app.Fragment; import android.os.Bundle; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.Button; import android.widget.TextView; import android.widget.Toast; import com.facebook.AccessToken; import com.facebook.AccessTokenTracker; import com.facebook.CallbackManager; import com.facebook.FacebookCallback; import com.facebook.FacebookException; import com.facebook.FacebookSdk; import com.facebook.GraphRequest; import com.facebook.GraphResponse; import com.facebook.Profile; import com.facebook.ProfileTracker; import com.facebook.login.LoginManager; import com.facebook.login.LoginResult; import com.facebook.login.widget.LoginButton; import org.json.JSONArray; import org.json.JSONException; import org.json.JSONObject; import java.net.MalformedURLException; import java.net.URL; import java.util.Arrays; import java.util.List; public class MainActivity extends Activity { Button fb; private CallbackManager callbackManager; private LoginManager loginManager; private List permissionNeeds= Arrays.asList("user_photos", "email", "user_birthday", "user_friends"); private String fbUserId; private String fbUserName; private String fbEmail; private String fbGender; private String fbDob; TextView txt; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); FacebookSdk.sdkInitialize(this); callbackManager = CallbackManager.Factory.create(); loginManager = LoginManager.getInstance(); setContentView(R.layout.activity_main); fb = (Button)findViewById(R.id.button); txt= (TextView)findViewById(R.id.txt); } public void onClick(View v) { /* if (v == fb) { loginButton.performClick(); }*/ FaceBookLogin(); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); callbackManager.onActivityResult(requestCode, resultCode, data); } private void FaceBookLogin() { loginManager.logInWithReadPermissions(MainActivity.this, permissionNeeds); loginManager.registerCallback(callbackManager, new FacebookCallback() { @Override public void onSuccess(LoginResult loginResult) { GraphRequest request = GraphRequest.newMeRequest( loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() { @Override public void onCompleted( JSONObject object, GraphResponse response) { Log.v("LoginActivity", response.toString()); try { fbUserId = object.getString("id"); fbUserName = object.getString("name"); fbEmail = object.getString("email"); fbGender = object.getString("gender"); fbDob = object.getString("birthday"); txt.setText(object.toString()); if (fbUserName.contains(" ")) { String first_name = fbUserName.substring(0, fbUserName.indexOf(' ')); String lastName = fbUserName.substring(fbUserName.indexOf(' ') + 1); } else { // first_name = fbUserName; //lastName = " "; } if (fbEmail != null) { // SendValueToServer(fbUserName, first_name, lastName, fbEmail); Toast.makeText(getApplicationContext(),"fbEmail"+fbEmail,Toast.LENGTH_SHORT).show(); } else { // SendValueToServer(fbUserName, first_name, lastName, " "); Toast.makeText(getApplicationContext(),"fbEmail:"+"blank",Toast.LENGTH_SHORT).show(); } } 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() { } @Override public void onError(FacebookException e) { } }); } } 

AndroidManifest.xml中

activity_main.xml中

设置，gradle这个

 include ':app', ':facebook-android-sdk-4.7.0'

使用我的代码更改onClickListener的部分：

 btnLoginFb.registerCallback(callbackManager, new FacebookCallback() { @Override public void onSuccess(LoginResult loginResult) { System.out.println("onSuccess"); progressDialog = new ProgressDialog(LoginActivity.this); progressDialog.setMessage("Procesando datos..."); progressDialog.show(); String accessToken = loginResult.getAccessToken().getToken(); Log.i("accessToken", accessToken); GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() { @Override public void onCompleted(JSONObject object, GraphResponse response) { Log.i("LoginActivity", response.toString()); // Get facebook data from login Bundle bFacebookData = getFacebookData(object); } } }); Bundle parameters = new Bundle(); parameters.putString("fields", "id, first_name, last_name, email,gender, birthday, location"); // Parámetros que pedimos a facebook 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()); } }); private Bundle getFacebookData(JSONObject object) { try { Bundle bundle = new Bundle(); String id = object.getString("id"); try { URL profile_pic = new URL("https://graph.facebook.com/" + id + "/picture?width=200&height=150"); Log.i("profile_pic", profile_pic + ""); bundle.putString("profile_pic", profile_pic.toString()); } catch (MalformedURLException e) { e.printStackTrace(); return null; } bundle.putString("idFacebook", id); if (object.has("first_name")) bundle.putString("first_name", object.getString("first_name")); if (object.has("last_name")) bundle.putString("last_name", object.getString("last_name")); if (object.has("email")) bundle.putString("email", object.getString("email")); if (object.has("gender")) bundle.putString("gender", object.getString("gender")); if (object.has("birthday")) bundle.putString("birthday", object.getString("birthday")); if (object.has("location")) bundle.putString("location", object.getJSONObject("location").getString("name")); return bundle; } 

并且不要忘记查看此行以获得更好的结果：

 parameters.putString("fields", "id, first_name, last_name, email,gender, birthday, location"); // Parámetros que pedimos a facebook 

希望，它也会帮助你:)

尝试这个它对我有用希望所以它也适合你

在您的主Activity或使用FaceBookSignIn方法的活动中调用此方法

 FacebookSdk.sdkInitialize(MainActivity.this); 

在您的活动中添加此方法

 public void FaceBookSignIn() { callbackManager = CallbackManager.Factory.create(); loginType = Constants.loginTypeFaceBook; LoginManager.getInstance().logInWithReadPermissions(MainActivity.this, Arrays.asList("email", "user_photos", "public_profile")); LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback() { @Override public void onSuccess(LoginResult loginResult) { DisplaySnackBar.display(getWindow().getDecorView().findViewById(android.R.id.content), "Success", true); GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() { @Override public void onCompleted(JSONObject jsonObject, GraphResponse graphResponse) { try { String email = jsonObject.getString(Constants.FacebookEmail), String name = jsonObject.getString(Constants.FacebookName), String firstName = jsonObject.getString(Constants.FacebookFirstName), String lastName = jsonObject.getString(Constants.FacebookLastName), String id = jsonObject.getString(Constants.FacebookID); } catch (JSONException e) { e.printStackTrace(); } } }); Bundle parameters = new Bundle(); parameters.putString("fields", "id,name,first_name,last_name,birthday,email"); request.setParameters(parameters); request.executeAsync(); } @Override public void onCancel() { DisplaySnackBar.display(getWindow().getDecorView().findViewById(android.R.id.content), "Sign In Cancel", true); } @Override public void onError(FacebookException e) { DisplaySnackBar.display(getWindow().getDecorView().findViewById(android.R.id.content), "Error", true); } }); }
