Not working in Android 10

[Datafox-JCP]

Hi, Does any one has Printooth working in Android 10?

I made an app and use this great printer function, works perfect in Android 9 but some one tested in Android 10 and does not work.

Thanks for your advice or suggestions.

@etman55 hi man, can you give detail where you put ACCESS_BACKGROUND_LOCATION ? on project manifest or , library manifest?

[etman55]

@semnazri Actually i used my own bluetooth implementation after that when i found the one in library not optimized for android 10.
then i added my paired device to the library through this :
Printooth.setPrinter(printerName, printerAddress)
