android - Invoke a method in Singleton class using reflection in java -

-

i have following class:

public class abcinfo {      private static abcinfo instance = null;     public static abcinfo getinstance(param param); // instance     private abcinfo(param); // making singleton class     public void methoda(param1 param1); // need invoke method }

using reflection in java, how can invoke methoda(). writing android application, want use method in existing(assume present time) application in phone.

below things have tried:

string apkname = activity.getpackagemanager().getapplicationinfo(packagename, 0).sourcedir;  pathclassloader mypathclassloader =     new dalvik.system.pathclassloader(     apkname,     classloader.getsystemclassloader());  class<?> handler = class.forname(classname, true, mypathclassloader); method m0 = handler.getdeclaredmethod("getinstance", new class[] { param.class  }); m0.setaccessible(true); object b = m0.invoke(null, new object[]{ param}); method m = handler.getmethod("methoda", new class[] { param1.class}); param1 methodparameter = "asdf"; object b1 = m.invoke(b, new object[] { methodparameter });

but still not working.

i found solution , below

object b1 = m.invoke(handler.newinstance(), new object[] { methodparameter });

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
