android - Device in Test Mode Admob -

i have doubt testmode in admob.

i have done test seen in app,

private void settestmode(boolean test) {          if (test) {             adrequest.addtestdevice(adrequest.test_emulator);             // galaxy s3 --elías             adrequest.addtestdevice("6xxxxxxxxxxxxxxxxxxxxxxx9");         }      } 

and in oncreate method use : settestmode(true); want upload app store. necessary put method "false", or can leave in "true"? users can have problems if leave in true?

thanks all!
