Onyx Boox Support

[ma-con]

I have long been looking for a cross-platform note taking app, and yours looks really perfect.
I was eager to try it on my Onyx Boox Tab Ultra (an Android 11 based eInk Tablet with Wacom layer) and while it works, writing or drawing is unfortunately quite laggy. I’m pretty sure, that this is because of the device and not your app, as this is also the case for other Android apps.
I was however wondering, if there is any possibility of improving the experience, as I think the app would be a perfect fit for the Boox devices, To the best of my knowledge, the only working note-taking apps are the included one and Microsoft One Note, both of which don’t allow for self-hosted sync. I’ve read that there is a possibility of integrating a SDK from Boox: https://github.com/onyx-intl/OnyxAndroidDemo/blob/master/doc/Onyx-Pen-SDK.md The app PngNote (https://github.com/karino2/PngNote) integrates this for example.

I don't have my Boox Note Air2 with me currently so please can you run this command on your computer with your tablet plugged in for USB debugging:

adb shell getprop ro.product.vendor.brand

or alternatively, run this on Termux on your tablet:

getprop ro.product.vendor.brand

I want to check if it's exactly "onyx" or if it's capitalised differently

It’s all caps:

$ getprop ro.product.vendor.brand
ONYX

I’ve seen that you worked on this already, this is really cool, thanks!

If there is anything I can help by testing, please let me know. I currently have a friend’s Nova Air 2 in addition to my Tab Ultra, so I could also test on two different devices with different screen sizes.

Btw: I feel a bit stupid for explaining what the Boox devices are and mentioning the SDK and so after realizing that own one as well and you even contributed to the PNGNote app 😉

Sorry about the commits referencing this issue; they reappear every time I rebase the onyxsdk_pen branch

Finally completed that! You can try out the new version before its official release here: Build #124

Thanks a lot, that is really great!
I've just tested it for a few minutes and it worked really well.

I'll certainly test it more in the coming days!

One thing I've just realized, which is probably not intended: Using the pencil, I can write beyond the "canvas", for example, I can write over the symbols in the toolbar and also the sidebar. Not a big problem as the lines disappear after a few seconds.
