if statement - If else condition not working on button click in Android -

-

if don't use condition on click call activity works, when use condition not responding, neither calling if section nor else:

btnupload.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             // uploading file server                                  try {                 strgetname = pref.getstring("key_name", null);                 strgetemail = pref.getstring("key_email", null);                  if (strgetemail.equals("")&&strgetname.equals("")) {                     toast.maketext(uploadactivity.this, "please create account first", toast.length_short).show();                     intent intent = new intent(uploadactivity.this, basicactivity.class);                     startactivity(intent);                 }                 else {                     new uploadfiletoserver().execute();                 }              } catch (exception e) {                 // todo: handle exception             }         }    });

there should space between && , strgetname.equals("") in if condition.

 if (strgetemail.equals("") && strgetname.equals(""))

and change

strgetname = pref.getstring("key_name", null); strgetemail = pref.getstring("key_email", null);

to

strgetname = pref.getstring("key_name", ""); strgetemail = pref.getstring("key_email", "");
