I think problem might be here. You have just declared your variable
private SimpleFacebook mSimpleFacebook;
you haven't initialized that variable so you got NPE
So initialized it on onCreateView() method.
mSimpleFacebook = SimpleFacebook.getInstance(getActivity());
And yet you get error then you need to finally change
mSimpleFacebook = SimpleFacebook.getInstance();
Add this line to manifest file..
<activity android:name="com.facebook.LoginActivity" android:screenOrientation="portrait" android:configChanges="keyboardHidden|orientation">
</activity>
which would be finally works for you.!!

You have to show your friend's profile picture with URL only.
You have to use only URL for showing your frnds profile picture.(This facility is given by Facebook)
you can show your friend's profile picture with Lazy Loading ..

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:
