That sounds like a mix of two Qt versions, since runOnAndroidThread is
defined
in qjnihelpers.cpp, inside QtCore, without any #if. That is, you're
compiling
against 5.12, but linking (or running) against 5.11. Check your
environment.
Did check, and do not find any reference to 5.11 in the build logs, have
no Qt related environment variables, moved my 5.11 tree away and did a
full rebuild, and the mobile app is telling in the log: build with
5.12.0, runtime from 5.12.0. So, while I would like to believe that
there is something wrong in my environment, I have hard time pinpointing
it.
This said, I just found something that seems related. Interfacing using
Bluetooth using the mobile app crashes. Logcat shows: AndroidRuntime:
java.lang.UnsatisfiedLinkError: No implementation found for void
org.qtproject.qt5.android.bluetooth.QtBluetoot
hBroadcastReceiver.jniOnReceive. So also here, a link time error.
Obviously, the big question is here: is this an error in the Subsurface
build process, or is there something missing in Qt 5.12 (as I believe I
use 5.12, and do not mix up versions). I can not be missing QtCore as
the app would not run in any way.
Let me answer my own question. I made a small android app from one of
the Qt examples. Embedded the runOnAndroidThread() call, and that
compiles and runs as expected. Ok, a fully different build environment
(qmake, clang) but it just works. So its a problem in our build process
and not an Qt issue.
