How to create session using FB page access token

Question

I created a long-lasting Facebook access token. I have a TestApp's app ID from Facebook. The issue is that I can't seem to get a valid session! What am I doing wrong?

public class MainActivity extends Activity {
    Facebook fb;

    @SuppressWarnings("deprecation")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        fb = new Facebook(getString(R.string.APP_ID));
        fb.setAccessToken(getString(R.string.ACCESS_TOKEN));
        //Expiry is set to 0, since the token never expires
        fb.setAccessExpires(0);



        if (fb.isSessionValid()) {

            Toast.makeText(this, "Session is valid",
                    android.widget.Toast.LENGTH_LONG).show();
            Log.d("TAG2", getString(R.string.ACCESS_TOKEN));

        } else
            Toast.makeText(this,
                    "Session is Invalid"+ getString(R.string.ACCESS_TOKEN),
                    android.widget.Toast.LENGTH_LONG).show();
            Log.d("TAG3", getString(R.string.ACCESS_TOKEN));


    }

}

Edited Code (I edited my original code to reflect the two answers given, but still it didn't help):

public class MainActivity extends Activity {
    Facebook fb;
    SharedPreferences prefs;

    @SuppressWarnings("deprecation")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

         prefs = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
         SharedPreferences.Editor editor = prefs.edit();
         editor.putString("AKEY",getString(R.string.ACCESS_TOKEN));
         editor.commit();
         editor.apply();

        fb = new Facebook(getString(R.string.app_id));
        fb.setAccessToken(prefs.getString("AKEY", ""));
        //Expiry is set to 0, since the token never expires
        fb.setAccessExpires(0);

        if (fb.isSessionValid()) {

            Toast.makeText(this, "Session is validd",
                    android.widget.Toast.LENGTH_LONG).show();
            Log.d("TAG2", getString(R.string.ACCESS_TOKEN));

        } else {
            Toast.makeText(this, fb.toString(),
                    android.widget.Toast.LENGTH_LONG).show();
            Log.d("TAG3", fb.toString() + fb.getAccessExpires()
                    + "Access Token is: " + fb.getAccessToken() +prefs.getString("AKEY", "")
                    + "Last update is:" + fb.getLastAccessUpdate()
                    + "Session is:" + fb.getSession());
        }

    }

}

@ItzikSamara No, I thought this was the standard way to get a session using FB's API. — user3163473, Aug 25 '14 at 09:28
if is it possible for you to add the Facebook Loginbutton i will write down full answer. — Itzik Samara, Aug 25 '14 at 09:39
@ItzikSamara Actually I just need to get the status from one page which I manage. Thats why i created the long-lasting token to just allow me monitor the page. Nobody else will be using it. — user3163473, Aug 25 '14 at 09:46

Use SharedPreference to store the session in Android.

Store

SharedPreferences settings = context.getSharedPreferences("KEY_NAME",
                context.MODE_PRIVATE);

Editor editor = settings.edit();
editor.putInt("fbsession", session);
editor.commit();
editor.apply();

Retrieve

 SharedPreferences settings = context.getSharedPreferences("KEY_NAME", context.MODE_PRIVATE);
 String fbSession = settings.getInt("fbsession", 1);

Could you give more details? What do you mean store the session? As you can see from the code, a valid session is simply not returned. – user3163473 Aug 25 '14 at 09:48
I tried the solution you provided, but I still have the issue. I have posted the edited code. – user3163473 Aug 25 '14 at 10:30

You can code like this to put value in prefs

SharedPreferences prefs = context.getSharedPreferences("com.projectname.pkgname",
            Context.MODE_PRIVATE);
prefs.edit().putString("facebook_accesstoken", "your_token").commit();

and get it like this

String facebook_accessstoken=prefs.getString("facebook_accesstoken", "");

I think the only explaination for this behaviour that I could think is that I was using a deprecated API. After having changed my code according to the new API it works now. Would have appreciated it had this been made clear in the Facebook documentation.

public class MainActivity extends Activity {

    SharedPreferences prefs;

    Session session;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        prefs = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
        SharedPreferences.Editor editor = prefs.edit();
        editor.putString("AKEY",getString(R.string.ACCESS_TOKEN));
        editor.putLong("expire", 0);
        editor.commit();
        editor.apply();

        Session.StatusCallback callback = new Session.StatusCallback()
                       {
           @Override
           public void call(
               Session session,
               SessionState state,
               Exception exception)
           {
             // safety check
             if (isFinishing())
               return;

             // check session state

             if (state.equals(SessionState.CLOSED)
                 || state.equals(SessionState.CLOSED_LOGIN_FAILED))
             {
             //  clearFacebookInfoFromSharedPreferences();
                 Log.d("TAG A","clearFacebookInfoFromSharedPreferences()");

               // specific action for when the session is closed
               // because an open-session request failed
               if (state.equals(SessionState.CLOSED_LOGIN_FAILED))
               {

                   Log.d("TAG B","cancelProgressDialog()");

               }
             }
             else if (state.equals(SessionState.OPENED))
             {
             //  cancelProgressDialog();


               Toast.makeText(MainActivity.this, "Succeeded connecting to Facebook",    android.widget.Toast.LENGTH_LONG).show();


               //handler.onSuccess();
             }
           }
         };

if (Session.getActiveSession() == null
                  && prefs.contains("AKEY")
                  && prefs.contains("expire"))
              {
                // open a session from the access token info
                // saved in the app's shared preferences

                String accessTokenString = prefs.getString(
                    "AKEY",
                    "");

                Date accessTokenExpires = new Date(prefs.getLong(
                    "expire",
                    0));

                AccessToken accessToken = AccessToken.createFromExistingAccessToken(
                    accessTokenString,
                    accessTokenExpires,
                    null,
                    null,
                    null);

                session=Session.openActiveSessionWithAccessToken(this, accessToken, callback);

            if (session != null) {

            Toast.makeText(this, "Session is valid",
                    android.widget.Toast.LENGTH_LONG).show();
            Log.d("TAG2", ""+session.getExpirationDate()+session.getAccessToken());

        } else {
            Toast.makeText(this, "Session is invalid",
                    android.widget.Toast.LENGTH_LONG).show();

        }




            Bundle params = new Bundle();

            params.putString("fields", "likes.limit(1).summary(true)");
            Request request = new Request(session, "922169881132606", params, HttpMethod.GET, new Request.Callback() {

                @Override
                public void onCompleted(Response response) {
                    try {
                        Log.d("TAG5", "In Try block");
                        GraphObject go = response.getGraphObject();
                        Log.d("graph object is", go.toString());
                        JSONObject obj = go.getInnerJSONObject();
                        JSONObject arr = obj.getJSONObject("likes"); 
                        JSONObject res = arr.getJSONObject("summary");
                        Log.d("TAG23", "JSON Set");
                       int numberOfLikes = res.getInt("total_count");
                       Log.d("Number of likes is ", Integer.toString(numberOfLikes));
                       Toast.makeText(MainActivity.this, "Number of likes is",
                                android.widget.Toast.LENGTH_LONG).show();
                    } catch (Exception e) {
                        Log.d("An error was thrown","alpha"+e);
                        e.printStackTrace();
                    }
                }
            });
            RequestAsyncTask task = new RequestAsyncTask(request);
            task.execute();
