i've got two devices one with Lollipop and one with Kitekat... the one with Lollipop does not report any error but when i try my application i obtain this error:

10-13 16:56:56.126: I/chromium(6322): [INFO:CONSOLE(99)] "Uncaught
TypeError: Object ALIM. IL SOLE DI LOPARDO MARIANGELA has no 
method 'startsWith'", source: file:///android_asset/www/soggetti3.html (99)

here is a part of my javascript:

 function onDeviceReady() {

        window.rancolor=ranColor();

        var ricerca=localStorage.getItem('testo_ricerca');
        var risultati = JSON.parse(localStorage["risultati"]);

        var ricerca1=ricerca.toString();
        ricerca1=ricerca1.toUpperCase();
        var res_match=[];

        var lll=risultati.length;

        for(var r=0;r<lll;r++){

            var ppp0=risultati[r][1].toString();
            var ppp1=risultati[r][0].toString();
            var ppp2=risultati[r][2].toString();
            var ppp3=risultati[r][3].toString();

            ppp0=ppp0.toUpperCase();
            alert(ppp0);
            alert(ricerca1);
            var check=ppp0.startsWith(ricerca1);

            if(check==true){
                res_match=res_match.concat([[ppp1,ppp0,ppp2,ppp3]]);
            }

        }
        var y=res_match.length;

how should i search an array of strings searching the strings that begin with some other string?

The easiest way to implement the startWith function is shown below, then you can use startsWith in your code:

if (typeof String.prototype.startsWith != 'function') {
  // see below for better implementation!
  String.prototype.startsWith = function (str){
    return this.indexOf(str) === 0;
  };
}
