No, Android always reports a pressure (but a constant value if your display doesn’t support pressure).
How does pressure sensitivity work?
I just installed your app, it’s fantastic, works like a charm.
I was just wondering how pressure sensitivity worked because to the best of my knowledge my Nexus 10 doesn’t have any such feature but when using GIMP2.8 it’s able to pick up the pressure using your app. So is it software or hardware side?
I’m happy that you like the app. GfxTablet pressure sensitivity is handled by the MotionEvent API automatically. I think if there’s no hardware support for pressure, the API tries to emulate it – so the pressure info should be available to all apps, no only GfxTablet.
