在尝试访问用户详细信息时，我收到此错误：

我无法在回调方法上捕获断点。如果您遇到此错误，请帮助。
下面是我获取用户详细信息的代码：
private void onSessionStateChange(Session session, SessionState state, Exception exception) {
//RFR//_("onSessionStateChange----------------");
/////////////// super.onSessionStateChange(state, exception);
if (state.isOpened()) {
readUserInfo(session);
} else if (state.isClosed()) {
// Session closed
}
}
private Request.GraphUserCallback graphCallback = new Request.GraphUserCallback() {
// callback after Graph API response with user object
@Override
public void onCompleted(GraphUser user, Response response) {
String name = user.getName();
String gender = (String) user.getProperty("gender");
String email = (String) user.getProperty("email");
String birthday = user.getBirthday();
Log.d("FB----->","name: "+ name +" gender: "+ gender +" email: "+ email +" birthday: " +birthday);
}
};
public void readUserInfo(Session session){
// make request to the /me API
Request.executeMeRequestAsync(session, graphCallback);
}
以下是我设置的权限：
openRequest.setPermissions(Arrays.asList("user_birthday", "email", "user_location"));
以下是我从图表api获得的响应，当从浏览器检查时：
{
"id": "1000000XXXXX930",
"name": "First Last",
"first_name": "First",
"last_name": "Last",
"link": "http://www.facebook.com/<myusername>",
"username": "<myusername>",
"gender": "male",
"locale": "en_US"
}

您是否已授予“电子邮件”权限，要求Facebook应用程序访问任何用户的电子邮件ID？
如果您想使用api访问Facebook用户的电子邮件ID，则必须提供电子邮件权限。有关用户个人资料的一般信息不会为您提供Facebook用户的电子邮件地址。
Email Permissions in Facebook API
注意：有些用户还将安全性设置为不与其他任何人共享电子邮件地址，那么您也可能无法获得电子邮件地址。
希望它会对你有所帮助。

你确实需要获取某人的电子邮件的权限，尽管有些人设置了他们的隐私，这样你就可以在没有这种明确许可的情况下收到他们的电子邮件，大多数人都没有。

这段代码在获取所需权限时可以正常使用 这也有助于您获得电子邮件权限
private void FaceBookSignIn()
{
facebookBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
Session currentSession = Session.getActiveSession();
if (currentSession == null || currentSession.getState().isClosed()) {
Session session = new Session.Builder(context).build();
Session.setActiveSession(session);
currentSession = session;
}
if (currentSession.isOpened()) {
Session.openActiveSession(SignIn_Rewards.this, false, new Session.StatusCallback() {
@Override
public void call(final Session session, SessionState state,
Exception exception) {
if (session.isOpened()) {
Request.executeMeRequestAsync(session,
new Request.GraphUserCallback() {
@Override
public void onCompleted(GraphUser user,
Response response) {
if (user != null) {
fromFB=true;
UserID=user.getId();
firstName=user.getFirstName();
Lastname=user.getLastName();
Gender=user.getProperty("gender").toString();
Email=user.getProperty("email").toString();
DateofBirth=user.getBirthday();
try {
getToken();
} catch (NoSuchAlgorithmException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
});
}
}
});
}
// Do whatever u want. User has logged in
else if (!currentSession.isOpened()) {
// Ask for username and password
OpenRequest op = new Session.OpenRequest((Activity) context);
op.setLoginBehavior(SessionLoginBehavior.SUPPRESS_SSO);
op.setCallback(null);
List<String> permissions = new ArrayList<String>();
permissions.add("publish_stream");
permissions.add("user_likes");
permissions.add("email");
permissions.add("user_birthday");
op.setPermissions(permissions);
Session session = new Session.Builder(SignIn_Rewards.this).build();
Session.setActiveSession(session);
session.openForPublish(op);
}
}
}) ;
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (Session.getActiveSession() != null)
Session.getActiveSession().onActivityResult(this, requestCode,
resultCode, data);
Session currentSession = Session.getActiveSession();
if (currentSession == null || currentSession.getState().isClosed()) {
Session session = new Session.Builder(context).build();
Session.setActiveSession(session);
currentSession = session;
}
if (currentSession.isOpened()) {
Session.openActiveSession(this, true, new Session.StatusCallback() {
@Override
public void call(final Session session, SessionState state,
Exception exception) {
if (session.isOpened()) {
Request.executeMeRequestAsync(session,
new Request.GraphUserCallback() {
@Override
public void onCompleted(GraphUser user,

if (user != null) {

Lastname=user.getLastName();

Email=user.getProperty("email").toString();
DateofBirth=user.getBirthday();
try {

// TODO Auto-generated catch block

你有这样的支票：
private Request.GraphUserCallback graphCallback = new Request.GraphUserCallback() {
// callback after Graph API response with user object
@Override
public void onCompleted(GraphUser user, Response response) {
String name = user.getName();
String gender = (String) user.getProperty("gender");
String email = (String) user.getProperty("email");
String birthday = user.getBirthday();
if(email!=null){
//perform your task here.
}else{
Log.v("email","is empty");
}
Log.d("FB----->","name: "+ name +" gender: "+ gender +" email: "+ email +" birthday: " +birthday);
}};

尝试此操作以获取电子邮件的价值 已修改：默认情况下，您无法收到电子邮件，因为您必须为电子邮件指定权限。
Session.StatusCallback statusCallback = new Session.StatusCallback()
{
@Override
public void call(Session session, SessionState state, Exception exception)
{
if(session.isOpened())
{
Request.executeMeRequestAsync(session, new Request.GraphUserCallback()
{
@Override
public void onCompleted(GraphUser user, Response response)
{
if(user != null)
{
try
{
System.out.println("Graph Inner Json"+user.getInnerJSONObject());
String email = user.getInnerJSONObject().getString("email");
}
}
}
}
}
}
YourActivityName.openActiveSession(this, true, statusCallback);
这是我们指定权限的openActiveSession()
private static Session openActiveSession(Activity activity, boolean allowLoginUI, Session.StatusCallback statusCallback)
{
OpenRequest openRequest = new OpenRequest(activity);
openRequest.setPermissions(Arrays.asList("user_birthday", "email"));
openRequest.setCallback(statusCallback);
Session session = new Session.Builder(activity).build();
if(SessionState.CREATED_TOKEN_LOADED.equals(session.getState()) || allowLoginUI)
{
Session.setActiveSession(session);
session.openForRead(openRequest);
return session;
}
return null;
}
最后你应该在onActivityResult方法中做：
if(Session.getActiveSession() != null)
{
Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}

if(object.has("email")){
userEmail = object.getString("email");
}
