fetching data from facebook and push notification from it

Is it possible to fetch data of user from FACEBOOK eg. pages he has liked. I need to fetch this info and generate push notification on android mobile. What should be approach and a reference would be much appreciated

try this to login, check session and get information from facebook , you can customized the permissions for the information you want.
private void performFacebookLogin()
{
Log.d("FACEBOOK", "performFacebookLogin");
final Session.NewPermissionsRequest newPermissionsRequest = new Session.NewPermissionsRequest(this, Arrays.asList("email"));
Session openActiveSession = Session.openActiveSession(this, true, new Session.StatusCallback()
{
#Override
public void call(Session session, SessionState state, Exception exception)
{
Log.d("FACEBOOK", "call");
if (session.isOpened() && !isFetching)
{
Log.d("FACEBOOK", "if (session.isOpened() && !isFetching)");
isFetching = true;
session.requestNewReadPermissions(newPermissionsRequest);
Request getMe = Request.newMeRequest(session, new GraphUserCallback()
{
#Override
public void onCompleted(GraphUser user, Response response)
{
Log.d("FACEBOOK", "onCompleted");
if (user != null)
{
Log.d("FACEBOOK", "user != null");
org.json.JSONObject graphResponse = response.getGraphObject().getInnerJSONObject();
String email = graphResponse.optString("email");
String id = graphResponse.optString("id");
//String facebookName = user.getUsername();
System.out.println("Birthday--------------"+user.getBirthday());
System.out.println("User ID----------------"+user.getId());
System.out.println("LINK---------------------"+user.getLink());
System.out.println("username---------------"+user.getUsername());
System.out.println("Hashcode----------------"+user.hashCode());
System.out.println("Inner JSON--------------"+user.getInnerJSONObject());
System.out.println("Location-------------------"+user.getLocation());
System.out.println("class------------------------"+user.getClass());
System.out.println(user.getProperty("email"));
if (email == null || email.length() < 0)
{
System.out.println(
"Facebook Login"+
"An email address is required for your account, we could" +
" not find an email associated with this Facebook account. Please associate a email with this account or login the oldskool way.");
return;
}
}
}
});
getMe.executeAsync();
}
else
{
if (!session.isOpened())
Log.d("FACEBOOK", "!session.isOpened()");
else
Log.d("FACEBOOK", "isFetching");
}
}
});
}

android facebook sdk - set permissions for openActiveSession

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

Get user ID and Email using Facebook SDK Android

I am trying to get the logged in user's id and email. Here is my code:
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 (response != null) {
Log.i(TAG,"User ID "+ user.getId());
Log.i(TAG,"Email "+ user.asMap().get("email"));
}
}
});
}
}
});
Everything goes ok till here
Log.i(TAG,"Access Token"+ session.getAccessToken());
I can see the access token, but the onComplete method is not called, and i don't get any user info.
what am i doing wrong?

Try
if (user != null)
instead of
if (response != null)
or try
Request.newMeRequest(...).executeAsync();

Android Facebook native app not getting user email and birthday even with permissions set and correct information in fields

I'm trying to get the user email and birthday (using a Me request). My app has email and user_birthday permissions and the fb account i'm using has an email and a birthday set.
When I try using the 'Graph API Explorer' (https://developers.facebook.com/tools/explorer) using the user access_token with 'fields=id,email,birthday' all I get is the id.
Can anybody advice me on this please.
Here is my code:
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 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) {
// here I check the infos I got.
Log.d("some tag", user.getInnerJSONObject().toString()); // it shows only the id, no email or birthday.
if (Session.getActiveSession() != null) {
Log.i(TAG, "Log out from FB");
Session.getActiveSession().closeAndClearTokenInformation();
}
}
}
});
// set params.
request.getParameters().putString("fields", "id,email,birthday");
// execute request.
request.executeAsync();
Log.d(TAG, request.toString());
}
if (exception != null) {
exception.printStackTrace();
}
}
});
Many thanks.

I finally changed the approach using the OpenRequest instead of getMeRequest:
Here is my code:
public void onClick(View v) {
Logger.d(TAG, "Start FB session");
// check if a session exists.
Session currentSession = Session.getActiveSession();
if (currentSession == null || currentSession.getState().isClosed()) {
// create a new session.
Session session = new Session.Builder(getApplicationContext()).build();
// set it a the active session.
Session.setActiveSession(session);
// keep a variable link to session.
currentSession = session;
}
// if a session is already open then issue a request using the available
// session. Otherwise ask for user credentials.
if (currentSession.isOpened()) {
// The user is logged in.
Logger.e(TAG, "User is logged in.");
Session.getActiveSession().closeAndClearTokenInformation();
Logger.i(TAG, "Session closed an token information cleared.");
// get user data here with no extra call.
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, Response response) {
if (user != null) {
Logger.i(TAG, "User:" + user.getInnerJSONObject());
}
}
});
}
}
});
} else {
// Ask for username and password
OpenRequest op = new Session.OpenRequest((Activity) this);
// don't use SSO.
op.setLoginBehavior(SessionLoginBehavior.SUPPRESS_SSO);
// no callback needed.
op.setCallback(null);
// set permissions.
List<String> permissions = new ArrayList<String>();
permissions.add("email");
permissions.add("user_birthday");
op.setPermissions(permissions);
// open session for read.
currentSession.openForRead(op);
Logger.d(TAG, "Session open for read request issued.");
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
Logger.d(TAG, "Request code is: " + requestCode);
Logger.d(TAG, "Result code is: " + resultCode);
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(getApplicationContext()).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, Response response) {
if (user != null) {
Logger.i(TAG, "User:" + user.getInnerJSONObject());
}
}
});
}
}
});
}
}
I hope this helps.

When you are using Request.GraphUserCallback(), its best to use it in MAIN UI THREAD
Session s = Session.getActiveSession();
if(s!=null)
{
Request.executeMeRequestAsync(s,new Request.GraphUserCallback()
{
#Override
public void onCompleted(GraphUser user, Response response)
{
if(user!=null)
{
try {
String fbid=null;
String birthday=null;
fbid=user.getId();
birthday=user.getBirthday();
} catch (JSONException e1) {
e1.printStackTrace();
}
}
}
});
}

you can try this also before the Request.executeMeRequestAsync(...){...}
List<String> permissions = session.getPermissions();
List<String> permissionsBirthday = new ArrayList<String>();
permissionsBirthday.add("user_birthday");
if (!isSubsetOf(permissionsBirthday, permissions)) {
pendingPublishReauthorization = true;
Session.NewPermissionsRequest newPermissionsRequest = new Session.NewPermissionsRequest(this, permissionsBirthday);
if (setPermissions(session, newPermissionsRequest))
return;
}
the method isSubsetOf();
private boolean isSubsetOf(Collection<String> subset, Collection<String> superset) {
for (String string : subset) {
if (!superset.contains(string)) {
return false;
}
}
return true;
}
hope this helps.

This code worked for me hope you find it useful. This retrieves the user email in 3 different ways and also logs it
try{
// new Read().execute("Facebook");
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.welcome);
// welcome.setText("Hello " + user.getName() + "!");
Log.d("useremai", (String) user.getProperty("email"));
Log.d("USER", user.getInnerJSONObject().toString());
JSONObject details = user.getInnerJSONObject();
useremail = details.optString("email");
Log.d("name", user.getName());
Log.d("email", useremail);
}
}
});
}
}
});
}catch(NoClassDefFoundError e){
e.printStackTrace();
}

Try this one:
if you have object of user than do below:
if (user != null) {
String UserId = user.getId();
try {
Log.i("Birthdate", ""+user.getInnerJSONObject().getString("birthday"));
} catch (JSONException e) {
e.printStackTrace();
}
}
