And here is my code to fetch information:
public void getProfileInformation(GraphUser user) {
Session session = Session.getActiveSession();
boolean enableButtons = (session != null && session.isOpened());
MainActivity.this.user = user;
TextView showName = (TextView) findViewById(R.id.showName);
if (enableButtons && user != null) {
showName.setText("Hello, " + user.getLastName());
} else {
showName.setText("Connect to sign up (or log in)");
}
}
}
When I run the code it says only "Connect to sign up (or log in)" option.
I dont know where am I missing to get user information ?
Can anybody help ?
Well, i managed with this finally.
if (enableButtons && user != null) {
showName.setText("Hello, " + user.getLastName());
Intent i = new Intent(this, NextPage.class);
i.putExtra("name",user.getName());
} else {
showName.setText("Connect to sign up (or log in)");
}

The first login was woking good, but when I logout and login again, it doesn't show popup and allow app login from fb. I want to show popup, help me!!!!
I have integrated Facebook in my Android App using Sessions. I have a Login Activity that has a button for Facebook login. I want to go to another activity called MainActivity after successful login to successful login in Facebook the app closes without any error or without going to the MainActivity. Can anyone suggest me where I should give the code to start the activity. Here is my code.
ImageButton buttonLoginLogout,bb;
Session.StatusCallback statusCallback = new SessionStatusCallback();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
buttonLoginLogout = (ImageButton)findViewById(R.id.imageButton1);

if (session == null) {
if (savedInstanceState != null) {
session = Session.restoreSession(this, null, statusCallback, savedInstanceState);

if (session == null) {
session = new Session(this);

Do it like this.
protected void onPostExecute(Bitmap bm){
//Drawable drawable = new BitmapDrawable(getResources(), bm);
Bitmap b1=bm;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
b1.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] b = baos.toByteArray();
// Log.w("bit",""+drawable);
String encodedImage = Base64.encodeToString(b,Base64.DEFAULT);
Editor edit=pref.edit();
edit.putString("image_data",encodedImage);
edit.commit();
Intent ik=new Intent(Login.this,MainActivity.class);
startActivity(ik);
}
};
t.execute();
Just move your
Intent ik=new Intent(Login.this,MainActivity.class);
startActivity(ik);
this code inside postexecute method.
if (state.isOpened()) {
// Request user data and show the results
Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {
#Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
// Display the parsed user info
}
}
});
}
I have tried follow the facebook doc to get the user info when at the onSessionStateChange function, the problem is , it is weird that I follow the offical doc and it shows
Request.executeMeRequestAsync is depreciate , so I wonder how to implement get the user info in latest facebook sdk 3.6 ? What I would like to do is get the user info if the user logined. Thanks a lot
Update:
Anyway I would also like to ask whether this way to implement login is correct? There are two place in my app need to login

Okay, Use below code.

// Code to retrieve data from FB
Session.openActiveSession(this, true, new Session.StatusCallback() {

I have tried a lot to integrate facebook login in my android app. I have succeeded partially. Now my problem is I couldn't redirect to another activity after successful facebook login. I think it is because I called the activity not from a proper place. I mean I coudn't call activity before the session close. I have attached my code here.

Please help me..
I'm new to android development. I've downloaded facebook sdk 3.0.1, and using the sample code to log in. The problem is, that if facebook app is installed the authentication fails.
(otherwise it works just fine)
after pressing the log in button I get to onActivityResult with status CLOSED_LOGIN_FAILED.
of course I'm not typing the password, it's done automatically through facebook's app, and the facebook app is logged in and works properly.
I couldn't find a solution..
please help me :)
this is my code:
#Override
protected void onCreate(Bundle savedInstanceState) {
instance = this;
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonLoginToFacebook = (Button) findViewById(R.id.buttonLoginToFacebook);
tvWellcome = (TextView) findViewById(R.id.tvWellcome);
Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
Session session = Session.getActiveSession();
if (session == null) {
if (savedInstanceState != null) {
session = Session.restoreSession(this, null, statusCallback,
savedInstanceState);
}
if (session == null) {
session = new Session(this);
}
Session.setActiveSession(session);
if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED)) {
session.openForRead(new Session.OpenRequest(this)
.setCallback(statusCallback));
}
}
updateView();
}
#Override
public void onStart() {
super.onStart();
Session.getActiveSession().addCallback(statusCallback);
}
#Override
public void onStop() {
super.onStop();
Session.getActiveSession().removeCallback(statusCallback);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode,
resultCode, data);
updateView();
}
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
Session session = Session.getActiveSession();
Session.saveSession(session, outState);
}
private void updateView() {
Session session = Session.getActiveSession();
if (session.isOpened()) {
Intent intent = new Intent(this, ScreenStartPage.class);
startActivity(intent);
} else {
buttonLoginToFacebook.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
onClickLogin();
}
});
}
}
private void onClickLogin() {
Session session = Session.getActiveSession();
if (!session.isOpened() && !session.isClosed()) {
session.openForRead(new Session.OpenRequest(this)
.setCallback(statusCallback));
updateView();
} else {
Session.openActiveSession(this, true, statusCallback);
}
}
public void onClickLogout() {
Session session = Session.getActiveSession();
if (!session.isClosed()) {
session.closeAndClearTokenInformation();
}
}
private class SessionStatusCallback implements Session.StatusCallback {
#Override
public void call(Session session, SessionState state,
Exception exception) {
updateView();
}

Have you setup your debug key hash and full class name on Facebook's app settings dashbaord? see steps 5 and 6 in the Getting Started with the Facebook SDK for Android doc.
