android - Make javascript injection compatible for api 16 -

-

i building android app have compatible api 14 , newer. have 1 method inside javascript interface.

from api 17 have add annotation method, @javascriptinterface, annotation not supported backwards api, since app target api 14 got error. if dont add annotation, javascript not trigged in mobile android 4.2.

is possible make kind of ifdef if deviceos newer 4.2?

set build target api level 17. set android:minsdkversion old of android want support. code compile and have @javascriptinterface annotation. lint point out places in code use classes, methods, etc. newer android:minsdkversion, can make sure doing correctly.

or, set android:targetsdkversion 16 or lower, in case @javascriptinterface not required. see http://developer.android.com/guide/webapps/webview.html#bindingjavascript.

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.
