Update notify method to strip escaped HTML characters.

[colonelpopcorn]

So, after doing some investigation I found that it was actually the notify method in the RemotePlayerService class. Not sure why some properties show escaped HTML characters instead of their standard equivalents, and it may be worth looking into why the characters are returned that way from the server. For now, however, this should suffice and allow special characters to be displayed without issue. See the before and after picture below for proof of bug fix, as well.

EDIT: This addresses issue #731, btw

Thanks for investigating this! Your fix looks good, but I found you could replace your helper function with a compat function from AndroidX.

The title is also used in some other places like the media session metadata. I'm not sure if we should fix the HTML in those places too.

[Maxr1998]

Are those shown somewhere where they wouldn't be decoded by the system?

[nielsvanvelzen]

Media session metadata can be read by any app and I don't think they expect HTML in the strings.

[Maxr1998]

Right. Should we still merge this already and have a different PR for the other issue?

[nielsvanvelzen]

Yeah that's fine
