service - Android: How to restrict specific apps -

-

in app, need block sms, email , phone. not detecting incoming or outgoing calls or sms. simply, have service run in background , check if of 3 processes running. if running activity open when user clicks on dialer or sms app. far, have tried, posting below:

service class

public class dialerservice extends service { activitymanager am; list<runningappprocessinfo> mappprocessinfoslist; private runnable myrunnable; boolean threaddone = true; handler mhandler; boolean islockedapprunning = false;  @override public ibinder onbind(intent arg0) {     return null; }  public void oncreate() {     = (activitymanager) getsystemservice(context.activity_service);     mappprocessinfoslist = new arraylist<activitymanager.runningappprocessinfo>();     mhandler = new handler();     log.v("dialer service", "oncreate called"); }  @override public int onstartcommand(intent intent, int flags, int startid) {     myrunnable = new runnable() {          @override         public void run() {             isrestrictedapprunning();         }     };      new thread(new runnable() {         public void run() {             while (threaddone) {                  try {                     mhandler.post(myrunnable);                 } catch (exception e) {                  }             }         }     }).start();     return start_sticky; }  private void isrestrictedapprunning() {     mappprocessinfoslist = am.getrunningappprocesses();     (int = 0; < mappprocessinfoslist.size(); i++) {         if (mappprocessinfoslist.get(i).processname                 .equals("com.android.phone")                 || mappprocessinfoslist.get(i).processname                         .equals("com.android.email")                 || mappprocessinfoslist.get(i).processname                         .equals("com.android.mms")) {             islockedapprunning = true;             intent dialogintent = new intent(getbasecontext(),                     testactivity.class);             dialogintent.addflags(intent.flag_activity_new_task);             getapplication().startactivity(dialogintent);         }     } }  @override public void ondestroy() {     super.ondestroy();     this.threaddone = false; } }

this code working has following issue:

it blocks apps, while requirement restrict apps have listed block. e.g., if blocking phone , sms, activity should open on click of dialer , sms app, , not when click on maps.

i not getting how this.

when detect blacklisted app coming up, need bring down running activity. background service/thread best handle activity monitor. there other internal methods using iactivitywatcher internal interface , related hidden apis subject deprecation. believe deprecated in jb.

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.
