Hi,

As discussed during the meeting, I've asked for permission to forward this to the mailing list so we all have the relevant information for the sonarpen :-)

We have completely rewritten the SDK in C++ code and it is not longer a wrapper of the java AAR file. The source are here: [DEV GREENBULB / SonarPen SDK C++ · GitLab (kde.org)](https://invent.kde.org/greenblub/sonarpen-sdk-cpp)

We modified the QT library to make use of the C++ SDK. We are able to use them to build a version of Krita v5.2.2 (we tried v5.2.3 but it is gives error message to several of our test devices. )  the v5.2.2 works very well and quick on all our devices. Here are all the related projects: [DEV GREENBULB · GitLab (kde.org)](https://invent.kde.org/users/greenblub/projects)

this the apk that we built:

Please be notice, the right now when Krita lost focus and regain focus, the pressure detection is off. User must manually replug the SonarPen to get the SDK works again. That's because QT is not related to the state of the app. My engineer advice to have Krita's onPause and onResume to stop and start the SonarPen SDK.

Error message on Krita 5.2.3
