About sleep apks on Onyx Boox Note 2 Air

Hi good evening,

Just bought an used Onyx Boox Note 2 Air and my idea is to use it for taking notes at meetings, ebook reader, documents reading & music at home through bluetooth.

I have already installed some apk, spotify, Moon+ Reader (i think reader at the boox is slighly better), dropbox, drive, onedrive and WPS Office to access to documents.

My question comes from when i want to reproduce music through spotify using bluetooth.

The problem comes when i do not touch the screen of the boox and it goes into sleep mode and so the music stops...

Is there a way to avoid certain apks when in use not to go into sleep mode?

Thanks!!!
