java - Android JavaScript Bridge - Trigger Events -

-

probably simple question, can call native function javascript, example:

android.setvolume(0.7)

however, not know how trigger (from android/java), or handle events (js) not caused user interaction, example, alerting js when user's network state changes, battery gets below point etc.

any appreciated.

as answer linked to, use loadurl() javascript: url, akin how bookmarklet works.

the answer on year old , labelled hack, still best way it?

i not clear why author of answer described hack. certainly, it's viable , used fair bit.

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...
