android facebook sdk 3.0 login and get user info -

-

i'm developing app using needs few facebook info register own website.

at first using facebook sdk 1.5, working well. until facebook says they'll stop supporting old(v2.0 , below) sdk since june 2013.

so have upgrade 3.0, , re-write code.

here's have done far after read facebook's official tutorial :

manifst.xml

<!-- stuff --> <uses-permission android:name="android.permission.internet" /> <meta-data android:name="com.facebook.sdk.applicationid" android:value="@string/fbappid"/> <activity android:name="com.facebook.loginactivity" android:label="@string/app_name" />

strings.xml

<!-- stuff --> <string name="fbappid">1234567890</string> <!-- know id fake, right ? -->

code

public class loginfragment extends sherlockfragment {   private uilifecyclehelper uihelper;    private session.statuscallback callback=new session.statuscallback()   {     @override     public void call(final session session, final sessionstate state, final exception exception)     {       onsessionstatechange(session, state, exception);     }   };    @override   public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate)   {     view view=inflater.inflate(r.layout.login_fragment, container, false);      loginbutton authbutton=(loginbutton)view.findviewbyid(r.id.btnlogin);     authbutton.setfragment(this);     authbutton.setreadpermissions(arrays.aslist("basic_info", "user_status", "email"));      return view;   }    @override   public void oncreate(bundle savedinstancestate)   {     super.oncreate(savedinstancestate);     uihelper=new uilifecyclehelper(getactivity(), callback);     uihelper.oncreate(savedinstancestate);   }    @override   public void onresume()   {     super.onresume();      // scenarios main activity launched , user     // session not null, session state change notification     // may not triggered. trigger if it's open/closed.     session session=session.getactivesession();     if(session!=null&&(session.isopened()||session.isclosed()))     {       onsessionstatechange(session, session.getstate(), null);     }      uihelper.onresume();   }    @override   public void onactivityresult(int requestcode, int resultcode, intent data)   {     super.onactivityresult(requestcode, resultcode, data);     uihelper.onactivityresult(requestcode, resultcode, data);   }    @override   public void onpause()   {     super.onpause();     uihelper.onpause();   }    @override   public void ondestroy()   {     super.ondestroy();     uihelper.ondestroy();   }    @override   public void onsaveinstancestate(bundle outstate)   {     try     {       super.onsaveinstancestate(outstate);       setuservisiblehint(true);       uihelper.onsaveinstancestate(outstate);     }     catch(exception e)     {       e.printstacktrace();       log.w(constants.tag, "error on save instance state, "+e.tostring());     }   }    private void onsessionstatechange(session session, sessionstate state, exception exception)   {     if(state.isopened()) //i don't know why state not opened......?     {       request request=request.newmerequest(session, new request.graphusercallback()       {         @override         public void oncompleted(graphuser user, response response)         {           if(user!=null)           {             log.i(constants.tag, "logged in...");             log.d("user fname", user.getfirstname());             log.d("user lname", user.getlastname());             log.d("user username", user.getusername());             log.d("user email", (string) response.getgraphobject().getproperty("email"));           }           else           {             log.i(constants.tag, "logged out...");           }          }       });        request.executebatchasync(request);     }   } }

when run app, can see facebook login button.

press it, dialog shows ask me allow app access facebook info, email...etc.

and after press yes, there nothing happen, nothing comes out in logcat...

how know user logged in facebook, , access info ?

you should override onactivityresult method , call

authbutton.onactivityresult(params);

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
