I'm currently developing an application which aims to authenticate any user by using Facebook acoount.
I have a trouble in getting user email from user's account. My code is below
private void signInWithFacebook() {
SessionTracker mSessionTracker = new SessionTracker(getBaseContext(), new StatusCallback() {
public void call(Session session, SessionState state, Exception exception) {
}
}, null, false);
String applicationId = Utility.getMetadataApplicationId(getBaseContext());
Session mCurrentSession = mSessionTracker.getSession();
if (mCurrentSession == null || mCurrentSession.getState().isClosed()) {
mSessionTracker.setSession(null);
Session session = new Session.Builder(getBaseContext()).setApplicationId(applicationId).build();
Session.setActiveSession(session);
mCurrentSession = session;
}
if (!mCurrentSession.isOpened()) {
Session.OpenRequest openRequest = null;
openRequest = new Session.OpenRequest(FacebookLoginActivity.this);
if (openRequest != null) {
openRequest.setDefaultAudience(SessionDefaultAudience.FRIENDS);
openRequest.setPermissions(Arrays.asList("user_birthday", "email", "user_location"));
openRequest.setLoginBehavior(SessionLoginBehavior.SSO_WITH_FALLBACK);
mCurrentSession.openForRead(openRequest);
}
}else {
Request.executeMeRequestAsync(mCurrentSession, new Request.GraphUserCallback() {
public void onCompleted(GraphUser user, Response response) {
Log.w("myConsultant", user.getId() + " " + user.getName() + " " + user.getLink() + " "+ response);
}
});
}
}
I am using Facebook SDK 3.0.1 for Android. I have set the permissions required by the Facebook Graph Api. In the response xml, there is no such field like email. Facebook Sdk documentations are not good enough and I don't know hot to obtain email address.
Thanks in advance.
Email is not a default field that's returned. Instead, you should create a meRequest, and pass it a parameter like: fields=email.
Request me = Request.newMeRequest(mCurrentSession, new GraphRequestCallback() {...});
Bundle params = me.getParameters();
params.putString("fields", "email,name");
me.setParameters(params);
me.executeAsync();
