Listview window does not appear in the downloaded apk application

Hi everyone!
I have a problem with the HM-10 connection
when I scan bluetooth devices the listview window does not appear in the downloaded apk application, but in the myth app inventor companion the listwiew window appears to me and I can guess without problems, does anyone know what the problem is?
this is for the downloaded .apk status scanning application but my devices do not appear


here when I connect with companion

Thank you
