import com.facebook.LoggingBehavior;
import com.facebook.Session;
import com.facebook.SessionState;
import com.facebook.Settings;

public class LoginUsingActivityActivity extends Activity {
    private static final String URL_PREFIX_FRIENDS = "https://graph.facebook.com/me/friends?access_token=";

    private TextView textInstructionsOrLink;
    private Button buttonLoginLogout;
    private Session.StatusCallback statusCallback = new SessionStatusCallback();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);
        buttonLoginLogout = (Button)findViewById(R.id.buttonLoginLogout);
        textInstructionsOrLink = (TextView)findViewById(R.id.instructionsOrLink);

        Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);

        Session session = Session.getActiveSession();
        if (session == null) {
            if (savedInstanceState != null) {
                session = Session.restoreSession(this, null, statusCallback, savedInstanceState);
            }
            if (session == null) {
                session = new Session(this);
            }
            Session.setActiveSession(session);
            if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED)) {
                session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
            }
        }

        updateView();
    }

    @Override
    public void onStart() {
        super.onStart();
        Session.getActiveSession().addCallback(statusCallback);
    }

    @Override
    public void onStop() {
        super.onStop();
        Session.getActiveSession().removeCallback(statusCallback);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        Session session = Session.getActiveSession();
        Session.saveSession(session, outState);
    }

    private void updateView() {
        Session session = Session.getActiveSession();
        if (session.isOpened()) {
            textInstructionsOrLink.setText(URL_PREFIX_FRIENDS + session.getAccessToken());
            buttonLoginLogout.setText(R.string.logout);
            buttonLoginLogout.setOnClickListener(new OnClickListener() {
                public void onClick(View view) { onClickLogout(); }
            });
        } else {
            textInstructionsOrLink.setText(R.string.instructions);
            buttonLoginLogout.setText(R.string.login);
            buttonLoginLogout.setOnClickListener(new OnClickListener() {
                public void onClick(View view) { onClickLogin(); }
            });
        }
    }

    private void onClickLogin() {
        Session session = Session.getActiveSession();
        if (!session.isOpened() && !session.isClosed()) {
            session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
        } else {
            Session.openActiveSession(this, true, statusCallback);
        }
    }

    private void onClickLogout() {
        Session session = Session.getActiveSession();
        if (!session.isClosed()) {
            session.closeAndClearTokenInformation();
        }
    }

    private class SessionStatusCallback implements Session.StatusCallback {
        @Override
        public void call(Session session, SessionState state, Exception exception) {
            updateView();
        }
    }

Android and Facebook: How to get picture of logged in User

I get deprecated error for this code:

Facebook mFacebook = new Facebook(APP_ID);
// ... user logs in ...
//String jsonUser = mFacebook.request("me/picture"); // throws error
String jsonUser = mFacebook.request("me");
JSONObject obj = Util.parseJson(jsonUser);
String facebookId = obj.optString("id");
String name = obj.optString("name");

Answer 1

You are getting Network on main thraed exception. So, try to do your process in a asynctask or try using,

if (android.os.Build.VERSION.SDK_INT > 9) {
                StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
                StrictMode.setThreadPolicy(policy);
            }

in your onCreate() after setContentView(R.layout.xxx) ;
