String test = String.valueOf(maxAmpFreq);
ArrayList<String> mylist = new ArrayList<String>();

public void onTick(long millisUntilFinished) {
Log.i("tag","A Kiss after 5 seconds");



public void onFinish() {
Log.i("tag","your test is......"+mylist);


but this not working correctly please guild me to solve this.


Problem is You declare your ArrayList Locally , That's why it have only one value at last. Every time its create new ArrayList .

Declare globally ....

private    ArrayList<String> mylist = new ArrayList<String>();

and use in the method for adding the value...


NOTE:- Try to declare variable globally, which is used in whole class methods.
