Add UI back/up button for devices without a back button.
Describe the solution you'd like I currently use this on a Supernote Manta, which runs android. I've installed the app via f-droid. The supernote does not have a system back button. Adding a toolbar with an up button would make it easier to navigate on devices like this.
Hi, sorry for the long delay. What do you mean by "does not have a system back button"? You should either have a back button, or a back gesture, don't you?
Unfortunately not, the device runs a custom Android and has no system back (button or gesture). It supports sideloading and I'm running easysync that way, via my fork with the toolbar back button added to all screens.
Can we programmatically determine if native back navigation (button or gesture) is available on the device?
I want to avoid adding an in-app back button if users already have a system one, as it might be confusing or unnecessary.
AFAIK, you can't. However, the app bar with a back button is standard design in material so I can't imagine it being that confusing.
