I am trying to integrate Facebook SDK to an android app. I got the code from Facebook manual. It uses Session.openActiveSession and then request a graph user. How could I request for more permissions without using LoginButton class?
Session.openActiveSession(this, true, new Session.StatusCallback() {
#Override
public void call(Session session, SessionState state, Exception exception) {
onSessionStateChange(session, state, exception);
if (session.isOpened()) {
Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {
#Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
// got user graph
} else {
// could not get user graph
}
}
});
}
}
});
Thank you.
Try this:
mCallback = new Session.StatusCallback() {...}; // the code you already have
Session.OpenRequest request = new Session.OpenRequest(mContext);
request.setPermissions(Arrays.asList("email", "user_birthday"));
request.setCallback(mCallback );
// get active session
Session mFacebookSession = Session.getActiveSession();
if (mFacebookSession == null || mFacebookSession.isClosed())
{
mFacebookSession = new Session(mContext);
Session.setActiveSession(mFacebookSession);
}
mFacebookSession.openForRead(request);
This solves the problem using opensession and extended persmission just once. Facebook SDK 3.5
Session s = new Session(this);
Session.setActiveSession(s);
Session.OpenRequest request = new Session.OpenRequest(this);
request.setPermissions(Arrays.asList("basic_info","email"));
request.setCallback( new Session.StatusCallback() {
// callback when session changes state
#Override
public void call(Session session, SessionState state, Exception exception) {
if (session.isOpened()) {
Request.newMeRequest(session, new Request.GraphUserCallback() {
#Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
Toast.makeText(getApplicationContext(), "User email is:"+user.getProperty("email"), Toast.LENGTH_SHORT).show(); }
else {
Toast.makeText(getApplicationContext(), "Error User Null", Toast.LENGTH_SHORT).show();
}
}
}).executeAsync();
}
}
}); //end of call;
s.openForRead(request); //now do the request above

Using facebook sdk version 3.0 & following is my code.I have getting id and name value but null email address every time.
authButton.setReadPermissions(Arrays.asList("basic_info","email"));
// session state call back event
authButton.setSessionStatusCallback(new
Session.StatusCallback() {
#Override
public void call(Session session,
SessionState state,
Exception exception) {
if (session.isOpened()) {
Log.i(TAG,"Access Token"+ session.getAccessToken());
Request.newMeRequest(session,
new Request.GraphUserCallback() {
#Override
public void onCompleted(GraphUser user,Response response) {
if (user != null) {
Log.i(TAG,"User ID "+ user.getId());
Log.i(TAG,"Email "+ user.asMap().get("email"));
}
}
}).executeAsync();
}
}
});
No need set Permissions as seperate for reading
Session.OpenRequest openRequest = new Session.OpenRequest(LandingPageActivity.this);
openRequest.setPermissions(Arrays.asList...);
openRequest.setCallback(new Session.StatusCallback() {
// callback when session changes state
#Override
public void call(Session session, SessionState state,
Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request request = Request.newMeRequest(session,
new Request.GraphUserCallback() {
// callback after Graph API response with user
// object
#Override
public void onCompleted(GraphUser user,
Response response) {
if (user != null) {
string email= user.getProperty("email");
}
}
});
request.executeAsync();
}
});
Session session = new Session(LandingPageActivity.this);
Session.setActiveSession(session);
session.openForRead(openRequest);

I'm attempting a log-in with FB with the code below. The GraphUser object has first name, last name, ID, but not email. I know I need to add permissions but how do I do it in this case. The permissions are generally added with Session.OpenRequest or the LogInButton but I'm not using those. Any suggestions?
Session.openActiveSession(activity, true, new Session.StatusCallback() {
// callback when session changes state
#Override
public void call(final Session session, SessionState state, Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request.newMeRequest(session, new Request.GraphUserCallback() {
// callback after Graph API response with user object
#Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
// get email from GraphUser
}
}
}).executeAsync();
}
}
});
I you have more than one permissions then make a list of permissions and call the performPublish() method (where you will be passing that Permission list as parameter) to publish a permission and with that check for the publish permission.
private static final List<String> PERMISSIONS = Arrays.asList("publish_actions", "email");
private void performPublish() {
Session session = Session.getActiveSession();
if (session != null) {
if (hasPublishPermission()) {
postStatusUpdate("name");
} else {
session.requestNewPublishPermissions(new Session.NewPermissionsRequest(this, PERMISSIONS));
}
}
}
private boolean hasPublishPermission() {
Session session = Session.getActiveSession();
return session != null && session.getPermissions().contains("publish_actions");
}
Just add the permissions as a parameter in openActiveSession:
Session.openActiveSession(activity, true, Arrays.asList("public_profile", "email"), new Session.StatusCallback() {
// callback when session changes state
#Override
public void call(final Session session, SessionState state, Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request.newMeRequest(session, new Request.GraphUserCallback() {
// callback after Graph API response with user object
#Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
// get email from GraphUser
}
}
}).executeAsync();
}
}
});
I can login to my app then share something. This needs an OPENED session state. However, when I am not logged in, then I want to share something, I need to open the session. I am using a ViewPager so e.g. when I go from one page to another and this code
Session.openActiveSession(getActivity(), true, new StatusCallback() {
#Override
public void call(Session session, SessionState state, Exception exception) {
}
});
is in the beginning of the code, then the session becomes active, and I get automatically logged in, which is wrong! That's why I put this code block into an onClickListener, so I only want to open the session if I click the share button in my app:
if (session != null && session.isOpened()) {
publishFeedDialog();
}
else {
Session.openActiveSession(getActivity(), true, new StatusCallback() {
#Override
public void call(Session session, SessionState state, Exception exception) {
}
});
publishFeedDialog();
}
private void publishFeedDialog() {
session = Session.getActiveSession();
Log.i("TAG", session.getState() + ""); //OPENING
WebDialog feedDialog = (
new WebDialog.FeedDialogBuilder(getActivity(),
Session.getActiveSession(),
params))
.setOnCompleteListener(new OnCompleteListener() {
#Override
public void onComplete(Bundle values,
FacebookException error) {
if (error == null) {
final String postId = values.getString("post_id");
if (postId != null) {
} else {
// User clicked the Cancel button
}
} else if (error instanceof FacebookOperationCanceledException) {
} else {
// Generic, ex: network error
}
}
})
.build();
feedDialog.show();
}
The error:
Attempted to use a session that was not open.
So I open the session in vain, because it is still OPENING when the WebDialog should appear.
Please help.
For me it works like this:
if (Session.getActiveSession() != null && Session.getActiveSession().isOpened()) {
publishFeedDialog();
}
else {
Session session = Session.getActiveSession();
if (!session.isOpened() && !session.isClosed()) {
// List<String> permissions = new ArrayList<String>();
// permissions.add("email");
session.openForRead(new Session.OpenRequest(this)
// .setPermissions(permissions)
.setCallback(mFacebookCallback));
} else {
Session.openActiveSession(getActivity(), true, mFacebookCallback);
}
}`
where callback is
private Session.StatusCallback mFacebookCallback = new Session.StatusCallback() {
#Override
public void
call(final Session session, final SessionState state, final Exception exception) {
if (state.isOpened()) {
String facebookToken = session.getAccessToken();
Log.i("MainActivityFaceBook", facebookToken);
Request.newMeRequest(session, new Request.GraphUserCallback() {
#Override
public void onCompleted(GraphUser user,
com.facebook.Response response) {
publishFeedDialog();
}
}).executeAsync();
Prefs.setStringProperty(getActivity(), R.string.key_prefs_facebook_token, facebookToken);
}
}
};
Try to call publishFeedDialog() in CallBack onCompleted
Try calling publishFeedDialog() from inside call() after you check for the status of the session (do not use session.isOpened(), use state.isOpened() instead). Checking the state ensures that your Session is in an open state and that it can also be used to execute requests. The StatusCallback can be called multiple times until the Session is actually open, that is why you should check the status before sending any request.
If you are opening a session from a fragment use the next openActiveSession method implementation.
openActiveSession(Context context, Fragment fragment, boolean allowLoginUI, Session.StatusCallback callback)
This works for me.
I want to add permission to get the email of the user, i am using this code
Session.openActiveSession(this, true, new Session.StatusCallback() {
#Override
public void call(Session session, SessionState state,
Exception exception) {
// TODO Auto-generated method stub
if (session.isOpened()) {
// make request to the /me API
Request.executeMeRequestAsync(session,
new Request.GraphUserCallback() {
#Override
public void onCompleted(GraphUser user,
Response response) {
if (user != null) {
et_firstName.setText(user
.getFirstName());
et_lastName.setText(user
.getLastName());
Log.e("email",
user.asMap().get("email")
+ "");
} else {
}
}
});
}
}
});
break;
I have tried googleing alot alot but all they talk about loginbutton but i don't want to use loginbutton,
any help would be appreciated

How to get user birthday by user.getBirthday() ?
Session.openActiveSession(this, true, new Session.StatusCallback() {
// callback when session changes state
#Override
public void call(Session session, SessionState state, Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {
// callback after Graph API response with user object
#Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
TextView welcome = (TextView) findViewById(R.id.textView1);
welcome.setText("Hello " + user.getBirthday() + "!");
Log.d("user_birthday","user_birthday:"+user.getBirthday());//user.getBirthday() this value always is null?
}
}
});
}
}
});
First of all have you set permission for user_birthday? it's very important if you want to access user_birthday information
if the user is not null usually you can get the birthday by user.getBirthday()
because from what I see you're using the new facebook SDK
you can set permission for example when you using the facebook authbutton
authButton.setReadPermissions(Arrays.asList("user_location", "user_birthday", "user_likes"));
or you can reauthorize permission
Session.ReauthorizeRequest reauthRequest = new Session.ReauthorizeRequest(this, PERMISSIONS).
setRequestCode(REAUTHORIZE_ACTIVITY).
setLoginBehavior(SessionLoginBehavior.SSO_WITH_FALLBACK);
session.reauthorizeForPublish(reauthRequest);
Where The PERMISSION is an array containing your permission
Small tip: It is possible to request permissions with the initial open-session request, thus no need for re-authorization:
final Session.OpenRequest request = new Session.OpenRequest(Activity.this);
request.setPermissions(Arrays.asList("email", "user_birthday")); // Your permissions here
request.setCallback(new Session.StatusCallback()
{
#Override
public void call(final Session session, SessionState state, Exception exception)
{
if (session.isOpened())
{
// Your code here
}
}
});
Session fbSession = Session.getActiveSession();
if (fbSession == null || fbSession.isClosed())
{
fbSession = new Session(Activity.this);
Session.setActiveSession(fbSession);
}
fbSession.openForRead(request);
Activity.this - your activity context.
Hope this helps somebody.. :)
