Try {
Isr = new InputStreamReader (new FileInputStream (fileUrl), "UTF-8 ");
BufferedReader read = new BufferedReader (isr );
String s = null;
List <String> list = new ArrayList <String> ();
While (s = read. readLine ())! = Null)
{
// System. out. println (s );
If (s. trim (). length ()> 1 ){
List. add (s. trim ());
}
}

System. out. println ("OK! ");
