java - AlertView that can be shown from background -

-

i have little problem alert view, idea when app starts, asks on background new data app, after receiving information alertview should shown if there new data. problem comes because alertview shown on main activity launched asynctask, if i'm in other activity, alert appear when come main activity , idea alertview displayed in whatever activity user in.

my first thought context send asynctask problem i've tried using getapplicationcontext() app crashes in moment of creating alertview. i'm, looking way display alertview or equivalent on screen wherever on app, 1 have ideas?

any idea appreciated

you can use broadcastreceiver in every activity contineous monitor background service contineous whenever event occoured using broadcastreceiver display alertbox content received receiver.

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
