I am building an android application that displays the Frequency of a sustained note with the FFT algorithm. I am using Jtransform methods. My issue currently is that I can\
Try replace
protected void onProgressUpdate(Double value){
//print the frequency
setContentView(R.layout.tuning);
String info = Double.toString(value);
with
protected void onProgressUpdate(Double... value){
//print the frequency
String info = Double.toString(value[0]);
For others not having jtransforms.jar, refer to http://sourceforge.net/projects/jtransforms/
