what am i doing wrong. i can sing in but i can't to show username in textview.
if anyone knows solution please help me
thanks

In your onComplete method you're trying to set the text of a UI element. Your onComplete method is getting called from a background(non main/UI thread). Any time you make a UI change, it must be on the UI thread. Try inserting a runOnUIThread call in your onComplete like this:
runOnUiThread(new Runnable() {
public void run() {
fb_name.setText(facebook_username);
}
});
Note: you will need to make variables declared outside the runnable final (ex: facebook_username)
Also note: most (if not all) web based calls will return on a background thread so you might need to use runOnUIThread frequently.

facebook sdk in android app, only able to login, but not able to logout?

in facebook sdk 3.0 logout not working
I have already tried
1.
Facebook mFb=new Facebook("xxxxxxxx");
mFb.logout(this);
2.
if (Session.getActiveSession() != null)
{
Session.getActiveSession().closeAndClearTokenInformation();
}
Session.setActiveSession(null);

Hope this may help you...
public void logoutFromFB()
mAsyncRunner.logout(this, new RequestListener() {
#Override
public void onComplete(String response, Object state) {
Log.d("Logout from FB", response);
if (Boolean.parseBoolean(response) == true) {
// User successfully Logged out
}
}
#Override
public void onIOException(IOException e, Object state) {
}
#Override
public void onFileNotFoundException(FileNotFoundException e,
Object state) {
}
#Override
public void onMalformedURLException(MalformedURLException e,
Object state) {
}
#Override
public void onFacebookError(FacebookError e, Object state) {
}
});
}

You can do this
clearUserPrefs(); // user prefrs
session.closeAndClearTokenInformation();
and invoke your facebook login activity
UPDATE:
You could use the traditional google account manager service to logout
AccountManager manager = (AccountManager) getSystemService(ACCOUNT_SERVICE);
Account[] accountsList = manager.getAccountsByType(ACCOUNT_TYPE); // ACCOUNT_TYPE = com.facebook.auth.login
for(int i=0;i<accountsList.length;i++)
manager.removeAccount(accountsList[i], null, null);

Why Facebook login page does not appear when I tried to re-login after I logged out in Android?

I followed this tutorial http://www.androidhive.info/2012/03/android-facebook-connect-tutorial/ to connect Facebook to my Android application. Instead of having many buttons, I have a button that will be used for both login and logout.
1) The first time I run the class, I could login and then logout successfully. And when I click on the same button to login again, the login page would not appear, however the Toast text "LOGGING IN" appear, which is after loginToFacebook() function in my if-else. Hence, I assume, it should have run the facebook login page like the first time I run the class. But the login page does not appear.
What did I do wrong? And what should I do?
2) And how do I display the username in String fbLoggedIn after logged in instead of the text "CONNECTED!!" ?
public class FacebookActivity extends Activity{
private static String APP_ID = "";
private Facebook facebook;
private AsyncFacebookRunner mAsyncRunner;
String FILENAME = "AndroidSSO_data";
private SharedPreferences mPrefs;
private Button backButton;
private String name = "CONNECTED!!";
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.settings_share);
facebook = new Facebook(APP_ID);
mAsyncRunner = new AsyncFacebookRunner(facebook);
RelativeLayout fbButton = (RelativeLayout) findViewById(R.id.fbLayout);
fbButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (!facebook.isSessionValid())
{
System.out.println("Not Connected. Clicked and Login.");
loginToFacebook();
Toast.makeText(getApplicationContext(), "LOGGING IN", Toast.LENGTH_LONG).show();}
else
{
System.out.println("Connected. Logged Out.");
logoutFromFacebook();
Toast.makeText(getApplicationContext(), "LOGGED OUT", Toast.LENGTH_LONG).show();}
}
});
}
public void loginToFacebook() {
mPrefs = getPreferences(MODE_PRIVATE);
String access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);
if (access_token != null) {
facebook.setAccessToken(access_token);
}
if (expires != 0) {
facebook.setAccessExpires(expires);
}
if (!facebook.isSessionValid()) {
facebook.authorize(this, new String[] { "email", "publish_stream" }, new DialogListener() {
#Override
public void onCancel() {
// Function to handle cancel event
}
#Override
public void onComplete(Bundle values) {
// Function to handle complete event
// Edit Preferences and update facebook acess_token
SharedPreferences.Editor editor = mPrefs.edit();
editor.putString("access_token", facebook.getAccessToken());
editor.putLong("access_expires", facebook.getAccessExpires());
editor.commit();
TextView fbUser = (TextView) findViewById(R.id.fbUser);
fbUser.setVisibility(View.VISIBLE);
String fbLoggedIn = name;
fbUser.setText(fbLoggedIn);
Toast.makeText(getApplicationContext(), "LOGGED IN AS " + name, Toast.LENGTH_LONG).show();
}
#Override
public void onError(DialogError error) {
// Function to handle error

#Override
public void onFacebookError(FacebookError fberror) {
// Function to handle Facebook errors
}
});
}
}
public void getProfileInformation() {
mAsyncRunner.request("me", new RequestListener() {

try {

// getting name of the user

// getting email of the user
final String email = profile.getString("email");
runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(), "Name: " + name + "\nEmail: " + email, Toast.LENGTH_LONG).show();
}
});
} catch (JSONException e) {
e.printStackTrace();
}
}
#Override

#Override

#Override

}
//logout from Facebook
public void logoutFromFacebook() {

public void onFileNotFoundException(FileNotFoundException e, Object state) { }
#Override
public void onMalformedURLException(MalformedURLException e, Object state) { }
#Override
public void onFacebookError(FacebookError e, Object state) { }
});
}
Just to be clearer, I set my if-else like this (extracted from the complete codes above).
RelativeLayout fbButton = (RelativeLayout) findViewById(R.id.fbLayout);
fbButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (!facebook.isSessionValid())
{
System.out.println("Not Connected. Clicked and Login.");
loginToFacebook();
Toast.makeText(getApplicationContext(), "LOGGING IN", Toast.LENGTH_LONG).show();}
else
{
System.out.println("Connected. Logged Out.");
logoutFromFacebook();
Toast.makeText(getApplicationContext(), "LOGGED OUT", Toast.LENGTH_LONG).show();}
}
});

This is the behavior that Facebook wants you to take with their API.Your login method checks to see if you have already signed in once and that the facebook session is active. If the session is active then it sets the properties of the facebook object and connects it behind the sences so that the login page does not show again.
So you're not doing anything wrong, it's suppose to happen this way.

How can i get the user id from the Facebook User?

I want to get the id from the Facebook User but what I've tried so far doesn't work...
public class fbLogin extends Activity {
public static final int LOGIN = Menu.FIRST;
public static final int GET_EVENTS = Menu.FIRST + 1;
public static final int GET_ID = Menu.FIRST + 2;
public static final String APP_ID = "361579407254212";
public static final String TAG = "FACEBOOK CONNECT";
private Facebook mFacebook;
private AsyncFacebookRunner mAsyncRunner;
private Handler mHandler = new Handler();
private static final String[] PERMS = new String[] { "user_events","email" };
private TextView mText;
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.onCreate(savedInstanceState);
// setup the content view
initLayout();
// setup the facebook session
mFacebook = new Facebook(APP_ID);
mAsyncRunner = new AsyncFacebookRunner(mFacebook);
if (mFacebook.isSessionValid()) {
AsyncFacebookRunner asyncRunner = new AsyncFacebookRunner(mFacebook);
asyncRunner.logout(this, new LogoutRequestListener());
} else {
mFacebook.authorize(this, PERMS, new LoginDialogListener());
}
mAsyncRunner.request("me", new IDRequestListener());
}
protected void initLayout() {
LinearLayout rootView = new LinearLayout(this.getApplicationContext());
rootView.setOrientation(LinearLayout.VERTICAL);
this.mText = new TextView(this.getApplicationContext());
this.mText.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
rootView.addView(this.mText);
this.setContentView(rootView);
}
private class LoginDialogListener implements DialogListener {
public void onComplete(Bundle values) {}
public void onFacebookError(FacebookError e) {}
public void onError(DialogError e) {}
public void onCancel() {}
}
private class LogoutRequestListener implements RequestListener {
public void onComplete(String response, Object state) {
// Dispatch on its own thread
mHandler.post(new Runnable() {
public void run() {
mText.setText("Logged out");
}
});
}
public void onIOException(IOException e, Object state) {}
public void onFileNotFoundException(FileNotFoundException e, Object state) {}
public void onMalformedURLException(MalformedURLException e, Object state) {}
public void onFacebookError(FacebookError e, Object state) {}
}
private class IDRequestListener implements RequestListener {
public void onComplete(String response, Object state) {
try {
// process the response here: executed in background thread
Log.d(TAG, "Response: " + response.toString());
JSONObject json = Util.parseJson(response);
final String id = json.getString("id");
fbLogin.this.runOnUiThread(new Runnable() {
public void run() {
mText.setText("Hello there, " + id + "!");
}
});
} catch (JSONException e) {
Log.w(TAG, "JSON Error in response");
mText.setText("catch1...");
} catch (FacebookError e) {
mText.setText("catch2");
}
}
public void onIOException(IOException e, Object state) {mText.setText("Logging out...1");}
public void onFileNotFoundException(FileNotFoundException e, Object state) {mText.setText("Logging out...2");}
public void onMalformedURLException(MalformedURLException e,Object state) {mText.setText("Logging out...3");}
public void onFacebookError(FacebookError e, Object state) {mText.setText("Logging out...4");}
}
}
It gives a Facebook Error when I go to the OnComplete method from the IDRequestListener class...
How can I fix it? Can anyone help me, please?

You can use socialauth android sdk. Can get user profile, post messages , gets friends list
http://code.google.com/p/socialauth-android/

authorize() is not synchronous and will return immediately. You'll need to wait for the authorization request to complete before submitting requests requiring an access token. Basically, fire the me request only when onComplete() has been called in the authorize() listener.
Also your activity seems to be missing the onActivityResult() implementation that feeds the Facebook object with authorization results, i.e.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
mFacebook.authorizeCallback(requestCode, resultCode, data);
}

Facebook connect function Logout with android sdk

My code is as below:
public void logoutFromFacebook() {
mAsyncRunner.logout(this, new RequestListener() {
#Override
public void onComplete(String response, Object state) {
Log.d("Logout from Facebook", response);
if (Boolean.parseBoolean(response) == true) {
runOnUiThread(new Runnable() {
#Override
public void run() {
// make Login button visible
btnFbLogin.setVisibility(View.VISIBLE);
// making all remaining buttons invisible
btnFbGetProfile.setVisibility(View.INVISIBLE);
btnPostToWall.setVisibility(View.INVISIBLE);
btnShowAccessTokens.setVisibility(View.INVISIBLE);
btnFbLogout.setVisibility(View.INVISIBLE);
}
});
}
}
#Override
public void onIOException(IOException e, Object state) {
}
#Override
public void onFileNotFoundException(FileNotFoundException e,
Object state) {
}
#Override
public void onMalformedURLException(MalformedURLException e,
Object state) {
}
#Override
public void onFacebookError(FacebookError e, Object state) {
}
});
}
But it does not work and show's an error validating access Token. Can anyone give me a solution for this?

The reason why the error message says "invalid application id" is because you are either not providing an app id or you are providing an invalid app id.
You have to make sure you instantiate Facebook in the beginning of your code in the following manner
Facebook facebook = new Facebook(YOUR_APP_ID_HERE);
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
