java - android animated menu background -

-

i developing android app @ moment. have main menu. pretty plain - 4 buttons in it. want background of menu animated live wallpaper f.e.

in fact want use static background image , slide 1-2 other images horizontal through it. did research , found out live wallpapers came api 2.1. , fit needs app should downcompatible api - when view animations, renderscript as. came api 3.1 , tutorials build on that.

so right im missing advice start of. apreciate every kind of help!

as adviced tried tween animations - pretty followed tutorial http://mobile.tutsplus.com/tutorials/android/android-sdk-creating-a-simple-tween-animation/

and in emulation device working charme .. when run on native api 2.1 device no animation shown .. havent considered ?

first of kudos class stacker gave me advice go tween animations - fit needs thx that! - unfortunately animation wasnt shown on api 2.1 devices.

following tuturial set tween animation "clouds_pass.xml" -

<set xmlns:android="http://schemas.android.com/apk/res/android" android:shareinterpolator="false" android:duration="80000" android:interpolator="@android:anim/linear_interpolator" android:fillafter="true" >  <translate     android:fromxdelta="155%p"     android:toxdelta="-100%p"     android:repeatcount="infinite" />

as activity calling tween - 

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      imageview clouds = (imageview)findviewbyid(r.id.clouds);     animation cloudspass = animationutils.loadanimation(this,r.anim.clouds_pass);     clouds.startanimation(cloudspass);  }

im not defintly sure might reason .. removing android:duration tag "clouds_pass.xml" , setting duration 

cloudspass.setduration(80000);

after loading animation fixed - , working intended down api 2.0 devices.

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
