Facebook SDK session provided in an unopened state

so I'm trying to refactor my app that uses the Facebook API to use fragments instead of activities. Before, after logging in with Facebook, I would get taken to a new activity - now, I'm trying to use fragments instead. However, ever since I started using fragments, it's been failing during requests, giving me an error "Session provided to a Request in un-opened state"
I added all the UIHelper lifecycle methods to my fragment, but I'm still getting the error. I basically copied the exact code that the example fragment uses, and I'm still getting this issue. Can anybody help me out? Here's my fragment, and the activity that sets it up (most of it is stock code taken directly from Facebook's example)
Fragment:
public class ConvoFragment extends Fragment {
String name;
ListView convos;
SwipeRefreshLayout rootView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
rootView = (SwipeRefreshLayout)inflater.inflate(R.layout.convos_fragment,
container, false);
convos = (ListView) rootView.findViewById(R.id.conversation_list);
name = getActivity().getSharedPreferences("global", 0).getString("myName", "");
Session session = Session.getActiveSession();
RequestAsyncTask req = new Request(session, "/me/inbox/", null, HttpMethod.GET, new Request.Callback()
{
public void onCompleted(Response response)
{
final Response resp = response;
try
{
if (response != null)
{
GraphObject asdf2 = response.getGraphObject();
Log.i("graphobject", response.toString());
//This logs the Session Provided to Request in unopened state error. Everything below will fail
JSONObject obj = asdf2.getInnerJSONObject();
JSONArray threads= obj.getJSONArray("data");
final ConvoAdapter adapter = new ConvoAdapter(getActivity(), convertArray(threads), name);
convos.setAdapter(adapter);
setupRefreshListener();
setupItemListener(adapter);
}
}
catch (JSONException e)
{
e.printStackTrace();
}
}
}).executeAsync();
return rootView;
}
So it fails right as it makes the request, because the request essentially returns null. Here's my activity that sets up the fragments:
public class LoginActivity extends AppCompatActivity {
private static final String USER_SKIPPED_LOGIN_KEY = "user_skipped_login";
private static final int SPLASH = 0;

}
}

}

if (isResumed) {

int backStackSize = manager.getBackStackEntryCount();
for (int i = 0; i < backStackSize; i++) {
manager.popBackStack();
}
// check for the OPENED state instead of session.isOpened() since for the
// OPENED_TOKEN_UPDATED state, the selection fragment should already be showing.
if (state.equals(SessionState.OPENED)) {
showFragment(FILE, false);
} else if (state.isClosed()) {
showFragment(SPLASH, false);
}
}
}
public void showFragment(int fragmentIndex, boolean addToBackStack) {
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction transaction = fm.beginTransaction();
for (int i = 0; i < fragments.length; i++) {
if (i == fragmentIndex) {
transaction.show(fragments[i]);
} else {

This uiHelper stuff is really confusing me. I'd appreciate if anybody could let me know what I might be doing wrong. I thought I followed the Facebook documentation (available here https://developers.facebook.com/docs/reference/android/3.23.1/class/UiLifecycleHelper/ ) exactly, but I'm still getting this error.

Facebook SDK import issues with Session and SessionState

I am relatively new to the android Facebook SDK and need help setting up my login activity after spending fruitless days on this. I am unable to resolve the issues and each time I try and import com.facebook.Session (as recommended in the tutorial, it is automatically changed to "SessionState" instead, which again doesn't help resolve the errors. Please can someone help me fix this.
I am using facebook sdk v3.6 and the latest ADT and SDK tools. Also, my facebook SDK is in a different folder (with the android SDK) and the project exists in a seperate workspace (again, as recommeneded by the tutorial, I did not choose to copy the fb sdk into my workspace, simply imported it). All the FB samples are working fine, I tried copying the code from Scrumptious's main activity to get my login working.
Here's the code for reference:

transaction.commit();
}
}

The error was resolved by removing the statement
import android.service.textservice.SpellCheckerService.Session;
and instead adding:
import com.facebook.Session;

Facebook Scrumptious fails authentication

I am new to android and was trying the Facebook login tutorial on following URl: https://developers.facebook.com/docs/android/scrumptious/authenticate/
I have created app exactly as explained in the tutorial. However, when i try to authenticate using facebook it fails. No error is shown in logcat. Everything seems fine, not even a single error, still its not authenticating.
Here is the code, its exactly same as in tutorial.

Please help as i have no clue what is wrong with the code. Thanks in advance.
P.S: I am running it on real device android version 4.2.2

Check app Id and key hash are correct. If not, i would just download folder into eclipse as an existing android project.

android facebook login

I have a android application through which i have to login to facebook.
I am using the session object of facebook sdk to login.
However the login does not work if the device has the actual facebook application installed in it.
Below is my code
public class FacebookSettings extends FragmentActivity{
/** Called when the activity is first created. */
private static final int LOGIN = 0;
private static final int LOGGED_IN = 1;
private static final int FRAGMENT_COUNT = LOGGED_IN +1;

pls help
thanks

I think you are looking for this :
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="#string/applicationId" />
This metadata is used by the facebook sdk to attach session to your application.
You can also set it while creating a session using the builder
new Session.Builder(this).setApplicationId(Constants.Facebook.APP_ID)
Refer to the AndroidManifest.xml in HelloFacebookSample

I think the problem is that key hash, which you have entered on Facebook page is different from key hash, which is sent by Facebook application. One of the solutions is to add following code in onCreate() method:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
PackageInfo info = getPackageManager().getPackageInfo(
"com.facebook.samples.loginhowto",
PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}
...
Replace com.facebook.samples.loginhowto with your package information. Look in a log for the KeyHash and add it in your developer page.
Additional information you can find on Facebook Developer page facebook.
But remember, this is temporary solution and will most likely work only for account, from which you got key hash with Facebook application.

We have faced the same kind of issue, but it was in IPhone app. When we develop a facbook application in IPhone, login does not work , if have intalled fb application itself.
We resolver it, put Iphone app bundle identifier in which I was created facebook app in facebook developer page.
I hope that this kind of similar feild missing when you was created a fb app for android in db developer page. Please check it.
