Facebook sdk 3.0.1 is not working properly

Question

I am trying to login into the Facebook using Facebook sdk .But it not logging in .Its opening the dialog box but after getting the credentials its not working . If i install the Facebook app it opens the Facebook app but login is not completed i cant get the token and user id . I cant post the message to the wall also . But it displays the toast that "message successfully displayed" but it is not posted in the Facebook wall. Code:

public boolean isSession() {
    access_token = sp.getString(TOKEN, "x");
    expires = sp.getLong(EXPIRES, -1);
    Log.d("TAG", access_token);

    if (access_token != null && expires != -1) {
        facebook.setAccessToken(access_token);
        facebook.setAccessExpires(expires);
    }
    return facebook.isSessionValid();
}

private class LoginDialogListener implements DialogListener {
    @Override
    public void onComplete(Bundle values) {
        Log.d("TAG", "LoginONComplete");
        token =facebook.getAccessToken();
        token_expires = facebook.getAccessExpires();
        Log.d("TAG", "AccessToken: " + token);
        Log.d("TAG", "AccessExpires: " + token_expires);

        savePrefs3(EXPIRES,token_expires);
        savePrefs(TOKEN,token);
        mAsyncRunner.request("me", new IDRequestListener());
    }

    @Override
    public void onFacebookError(FacebookError e) {
        Log.d("TAG", "FacebookError: " + e.getMessage());
    }

    @Override
    public void onError(DialogError e) {
        Log.d("TAG", "Error: " + e.getMessage());
    }

    @Override
    public void onCancel() {
        Log.d("TAG", "OnCancel");
    }
}

private class IDRequestListener implements RequestListener {
    @Override
    public void onComplete(String response, Object state) {
        try {
            Log.d("TAG", "IDRequestONComplete");
            Log.d("TAG", "Response: " + response.toString());
            JSONObject json = Util.parseJson(response);

            Uid = json.getString("id");
            savePrefs("UID", Uid);
            final String name = json.getString("name");
        } catch (JSONException e) {
            Log.d("TAG", "JSONException: " + e.getMessage());
        } catch (FacebookError e) {
            Log.d("TAG", "FacebookError: " + e.getMessage());
        }
    }

    @Override
    public void onIOException(IOException e, Object state) {
        // TODO Auto-generated method stub
    }

    @Override
    public void onFileNotFoundException(FileNotFoundException e, Object state) {
        // TODO Auto-generated method stub
    }

    @Override
    public void onMalformedURLException(MalformedURLException e, Object state) {
        // TODO Auto-generated method stub
    }

    @Override
    public void onFacebookError(FacebookError e, Object state) {
        // TODO Auto-generated method stub
    } 
}

public void postToWall(String message){
    Bundle parameters = new Bundle();
    parameters.putString("message", message);
    parameters.putString("description", "topic share");
    try {
        facebook.request("me");
        String response = facebook.request("me/feed", parameters, "POST");
        Log.d("Tests", "got response: " + response);
        if (response == null || response.equals("") ||
            response.equals("false")) {
            showToast("Blank response.");
        } else {
        showToast("Message posted to your facebook wall!");
        }
        finish();
    } catch (Exception e) {
        howToast("Failed to post to wall!");
        e.printStackTrace();
        finish();
    } 
}

private void showToast(String message) {
    Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show();
}

please tell me where i am going wrong . after displaying a toast app gets closed. while loading the fb dialog if i touch the screen it either reloads or switching back to the app window. Please give immediate reply

The Facebook object is depreciated.You can use the following code in your activity oncreate() method.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);



    requestWindowFeature(Window.FEATURE_NO_TITLE);

//  setContentView(R.layout.facebook_dialog);
    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) {



         Toast.makeText(LoginFacebook.this.getApplicationContext(), 
                                    "Facebook Error",

Toast.LENGTH_LONG).show();

 finish();
                        }
                        else
                        {

         Toast.makeText(LoginFacebook.this.getApplicationContext(), 
                                    user.getName()+" Logged in Successfully.",
                                    T    
   Toast.LENGTH_LONG).show();
                            finish();
                        }
                        //login_fb.setEnabled(true);
                        //progress.setVisibility(View.INVISIBLE);
                    }

                });


            }
        }
    });


}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);
  Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
  finish();
}

And use the following code in the Manifest.xml file under the application tag.

    <meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/app_id" />

    <activity
        android:name="com.facebook.LoginActivity"
        android:label="@string/app_name" >
    </activity>

After Loging in to post to wall you have to call this method...

       private void publishStory(String user) {
    try {
        Session session = Session.getActiveSession();

        if (session != null){

            // Check for publish permissions    
            List<String> permissions = session.getPermissions();
            if (!isSubsetOf(PERMISSIONS, permissions)) {
                pendingPublishReauthorization = true;
                Session.NewPermissionsRequest newPermissionsRequest = new Session
                        .NewPermissionsRequest(this, PERMISSIONS);
                session.requestNewPublishPermissions(newPermissionsRequest);
                return;
            }

            Bundle postParams = new Bundle();
            postParams.putString("message", messageToPost);

            Request.Callback callback= new Request.Callback() {
                public void onCompleted(Response response) {
                    JSONObject graphResponse = response
                            .getGraphObject()
                            .getInnerJSONObject();
                    String postId = null;
                    try {
                        postId = graphResponse.getString("id");
                    } catch (Exception e) {
                        Log.i("Test",
                                "JSON error "+ e.getMessage());
                    }
                    FacebookRequestError error = response.getError();
                    if (error != null) {
                        Toast.makeText(ShareOnFacebook.this
                                .getApplicationContext(),
                                error.getErrorMessage(),
                                Toast.LENGTH_SHORT).show();
                    } else {

                        progress.setVisibility(View.INVISIBLE);
                        toastmessage="Posted Successfully";
                        Toast.makeText(ShareOnFacebook.this
                                .getApplicationContext(),
                                toastmessage,
                                Toast.LENGTH_SHORT).show();

                    }
                }
            };

            Request request = new Request(session, user+"/feed", postParams, 
                    HttpMethod.POST, callback);

            RequestAsyncTask task = new RequestAsyncTask(request);
            task.execute();
        }
    } catch (Exception e) {
        // TODO Auto-generated catch block
        Toast.makeText(ShareOnFacebook.this
                .getApplicationContext(),
                "Facebook Error",
                Toast.LENGTH_SHORT).show();
    }

}
private boolean isSubsetOf(Collection<String> subset, Collection<String> superset) {
    for (String string : subset) {
        if (!superset.contains(string)) {
            return false;
        }
    }
    return true;
}

and declare the variables as..

private static final List<String> PERMISSIONS =    Arrays.asList("publish_actions","manage_pages","publish_stream");
private static final String PENDING_PUBLISH_KEY = "pendingPublishReauthorization";
private boolean pendingPublishReauthorization = false;
