    File = new file (Environment.getexternalstoragedirectory (). GetPath ()); 
 File = new file ("/sdcard/");   info = getString (r.string.info); 
  Search_btn.setonclicklistener (this); 
    @Override public void OnClick (View v) {//TODO auto-generated Method Stub path = ""; 
    Result.settext (""); 
    Key = Et.gettext (). toString (); 
  Browserfile (file); } public void Browserfile (File fileold) {if (Key.equals (")) {Toast.maketext (this, getString (r.string
