public class FacebookActivity extends Activity implements OnClickListener
{
Facebook fb;
//ImageView pic;
CircularImageView pic;
ImageView button;
TextView welcome,location;
SharedPreferences sp;
String APP_ID = "xxxxxxxx";
String name;
String id;
String town;
String currentCity;
String imgurl_check;
Drawable d ;
Bitmap bitmap;
String access_token;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fb = new Facebook(APP_ID);
sp = getPreferences(MODE_PRIVATE);
access_token = sp.getString("access_token", null);
long expires = sp.getLong("access_expires", 0);
if(access_token !=null)
{
fb.setAccessToken(access_token);
}
if(expires !=0)
{
fb.setAccessExpires(expires);
}
button = (ImageView) findViewById(R.id.login);
welcome = (TextView) findViewById(R.id.name);
location = (TextView) findViewById(R.id.location);
//pic = (ImageView) findViewById(R.id.picture_pic);
pic = (CircularImageView) findViewById(R.id.picture_pic);
button.setOnClickListener(this);
updateButtonImage();
}

{
if(fb.isSessionValid())
{
//button.setImageResource(R.drawable.fb_logout);
button.setVisibility(View.INVISIBLE);
