Kind of a PSA/update here for anyone who is interested in Krita on Android devices (and a small rant against Wacom).
I did a bit more digging, and the Android API version used to port Krita is for Android 5.0. That means that Krita will not work on the Wacom Cintiq Companion Hybrid (Android 4.2.1) at this time. As much as I’d LOVE Krita on my cintiq on the go, that should probably be an “eventually maybe, if ever” request.
Since the Cintiq is probably the only real drawing tablet that’s running such an older version of Android, I’m not sure if backporting to an earlier Android API for the Cintiq would even be possible/feasible/worth it at all. If it isn’t possible, then I’d blame Wacom more than anyone else. The only Software update they ever gave that thing was some minor unspecific bug fixes and the ability to see the stylus cursor on the screen. It’s to the point that Google Chrome on this thing is now almost 40 versions behind (Can install as far as version 42, the Current release is version 79). Thanks Wacom.
On better notes, Krita on my Samsung Galaxy Tab S3 works pretty much as it should, except I cannot find the options (File, Edit, View, etc), and I cannot toggle my onscreen keyboard. Hopefully this is an easy fix or I’m missing something simple/obvious.
What I didn’t expect is that Krita for Android works flawlessly on my Acer Chromebook Spin 11, pressure sensitivity on the stylus and everything. Awesome! It runs better than the Linux appimage, even. That’s likely because Linux for Chromebooks is still in beta, and does not have HW acceleration.
