Facebook Android Integration: Should not pass a read permission error

I am developing an android app, where the user should be able to log in with a Facebook account. The application has worked in the first 5-10 min. I could see the layout where i was prompted to give/deny permissions.
When i try to log in, it shows me the "Loading" message from Facebook API but then returns to the previous layout.
The error message i receive is: "Should not pass a read () permission to a request for publish or manage authorization".
I appreciate any help to resolve this issue..

When i click on the button, the ListView opens but with no data i.e. Empty set.
Contacts_View.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<TextView android:id="#android:id/empty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Empty set"
/>
</LinearLayout>
What i mean here is that both the functions are identical.getGPosts() is called in the FBAppActivity whereas the createAdapter() is called in MessagesActivity.getGPosts() works but createAdapter() does not. Kindly help me understand why is this happening.
Basically i am trying to import posts from a facebook group. My Toast object is working fine from the getGPosts() [it is in the FBAppActivity class] function. This function getGPosts() is called on the button click.I verified that i am getting the data using the Toast object. Now i want to populate the data to a ListView. Which i am unable to do. I have tried various methods, but none has worked out for me.

Because you're calling the setListAdapter(adapter) for implicit (Activity's) ListView in the onCreate(Bundle savedInstanceState) method and in the getGPosts() method you reference the correct (visible) ListView.
Simply change the mentioned call in the onCreate(Bundle savedInstanceState) method to:
myListView = getListView();
myListView.setAdapter(adapter);
And you should be fine! Good luck!
P.S. This solution will work if your ListActivity follows the following requirement:
your own view MUST contain a ListView object with the id "#android:id/list"
from Google's documentation

As I see you are extending ListActivity. So below code must throw a NPE.
lv = (ListView)findViewById(R.id.list);
lv.setAdapter(adapter);
You should use below code at onComplete method instead;
setListAdapter(adapter);
or
getListView().setAdapter(adapter);

Android Facebook integration does not log out

I am developing a Facebook Android integration using the below code, but once I log-in through this app then it does not logout from facebook even if I logout from Facebook app or browser both from my device. So this android app can still post on my Facebook wall. How do I logout from this app if I logout from my facebook app or facebook on browser.

You can't force a logout from your app if you logout of the Facebook app, at least no API that we support with our SDK.
In theory, you could find a way to attach some sort of uninstall intent or to parse logs for any messages regarding facebook logout, but it generally is not recommended as best practice to force a logout of another app when another app logs out (its not intuitive to the user that this is going to happen).

try remove this code
if (access_token != null) {
facebook.setAccessToken(access_token);
Log.d("FB Sessions", "" + facebook.isSessionValid());
}

I logged in to preinstalled Facebook app in my device. And I got this screen only.
And in my Logcat this line appears.
09-28 15:18:24.652: E/ActivityThread(1201): Failed to find provider info for com.facebook.katana.provider.AttributionIdProvider
If I logged out from my preinstalled Facebook app, my application prompts me to login, asking the credentials. That time also, the empty screen appears.But in the preinstalled Facebook app, I can see my updates.( I get Logged in).
Update:
Right now I'm checking the app only. I have not published it to market. I got the key by referring this site http://sean.lyn.ch/2011/07/android-the-facebook-sdk-sso-and-you/. And I added it to the app, like this.
Update 2:
Now I got these lines in logcat:
