google cloud messaging - Pass Additional value to Android GCM onRegistered method -

-

i want pass additional value gcm onregistered method, because want check if user unregistered , want call gcmregistrar.register(registrationactivity.this, sender_id); , pass existing user id onregistered method. question how pass additional value can value in onregistered. 

package bd.org.basis.projectmanagement;  import android.content.context; import android.content.intent; import android.util.log;  import com.google.android.gcm.gcmbaseintentservice; import static bd.org.basis.projectmanagement.registrationactivity.sender_id;;  public class gcmintentservice extends gcmbaseintentservice {     public gcmintentservice() {         super(sender_id);     }      @override     protected void onerror(context context, string error) {         // todo auto-generated method stub      }      @override     protected void onmessage(context context, intent intent) {         // todo auto-generated method stub         log.e("onmessage", "see later");         string title=intent.getstringextra("title");         string type=intent.getstringextra("type");         string msg=intent.getstringextra("msg");         string url=intent.getstringextra("url");          log.e("onmessage", title+"--"+type+"--"+msg+"-- "+url);      }      @override     protected void onregistered(context context, string token) {         // todo auto-generated method stub         log.e("onregistered", token);      }      @override     protected void onunregistered(context context, string token) {         // todo auto-generated method stub      }  }

you can't add parameter onregistered, since can't change signature of method overriding.

why want it? want onregistered called when app registered? calling gcmregistrar.register that, , if app registered, existing registration id passed onregistered anyway, don't need new parameter.

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

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
