android - problems with Request.executeMeRequestAsync(session, Request.GraphUserCallback()) function -

-

i'm following tutorial login on android application using facebook.

i've had many problems hash keys , , think i've solve them all, because session gets opened state.

the problem i'm having after log in facebook, when session opened, code executes request.executemerquestasync() , never enters oncomplete() part... idea?

here code...

package com.example.firstandroidapp;  import java.security.messagedigest; import java.security.nosuchalgorithmexception;  import android.app.activity; import android.content.intent; import android.content.pm.packageinfo; import android.content.pm.packagemanager; import android.content.pm.packagemanager.namenotfoundexception; import android.content.pm.signature; import android.os.bundle; import android.util.base64; import android.util.log; import android.widget.textview;   import com.facebook.request; import com.facebook.response; import com.facebook.session; import com.facebook.sessionstate; import com.facebook.model.graphuser;  public class mainactivity extends activity { @override   public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      // start facebook login     session.openactivesession(this, true, new session.statuscallback() {        // callback when session changes state       @override       public void call(session session, sessionstate state, exception exception) {           try {                 packageinfo info = getpackagemanager().getpackageinfo("com.example.firstandroidapp",                                             packagemanager.get_signatures);                 (signature signature : info.signatures) {                     messagedigest md = messagedigest.getinstance("sha");                     md.update(signature.tobytearray());                     log.i("digest: ", base64.encodetostring(md.digest(), 0));                 }             } catch (namenotfoundexception e) {                 log.e("test", e.getmessage());             } catch (nosuchalgorithmexception e) {                 log.e("test", e.getmessage());             }            if (session.isopened()) {            // make request /me api           request.executemerequestasync(session, new request.graphusercallback() {              // callback after graph api response user object             @override             public void oncompleted(graphuser user, response response) {               // never gets here...                   if (user != null) {                 textview welcome = (textview) findviewbyid(r.id.welcome);                 welcome.settext("hello " + user.getname() + "!");               }             }           });         }       }     });   }    @override   public void onactivityresult(int requestcode, int resultcode, intent data) {       super.onactivityresult(requestcode, resultcode, data);       session.getactivesession().onactivityresult(this, requestcode, resultcode, data);   }  }

thanx in advance. david.

i had same problem.

the tutorial tells modify androidmanifest.xml. in modification put tags below in wrong places (i didn't use eclipse modify manifest file) , prevented callback.

<manifest ...>   ...   <application ...>     ...     <activity android:name="com.facebook.loginactivity"/>     ...     <meta-data android:name="com.facebook.sdk.applicationid" android:value="@string/app_id"/>     ...   </application>   ...   <uses-permission android:name="android.permission.internet"/>   ... </manifest>

try double-check androidmanifest.xml. the official document helpful.

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...
