[Krita Artists] [PM] RE: SonarPen is working in Krita 5.2.2 on Android phone and Tablet

[Dmitry Kazakov]

Hi, Halla!

I have made a roadmap for integration of the SonarPen SDK into Krita:
https://phabricator.kde.org/T17515

The first two things that we should do before we can start the porting work
is:

1) Talk to sysadmins for a common location for Krita build tools and
utilities. Basically, where should we put this repository with the SDK? Are
SonarPen people going to maintain it? Should they publish it under KDE's
gitlab or official gitlab/github?

2) We need to ask the wider KDE community to review the SDK's code
security-wise (to avoid cases like the one that happened to libxz). This
library is going to be loaded in every single instance of Krita running on
any Android device. It doesn't matter if the device has SonarPen or not.

PS:
About the safe assert error reported by SonarPen: it should be fixed in
`krita/5.2` branch!
