array codes here 

public static string[] bilgiler;         stringarray = parsejson(result);         sayaca=(integer)stringarray.length;         tvdata2.settext("burası arrayden geliyor :" + stringarray[1].tostring() + sayaca );         sayacim = sayaca;         bilgiler = new string[sayacim];         bilgiler = stringarray;         setuptoolbar();         initnavigationdrawer();

try this:

private int counter = 0;  (int = 0; < x; i++) {     //in interface     ....bilgiger[counter]     //at end    counter++; }
