Thank you.

I installed in the container made by Ubuntu SDK all you mentioned except qt5 which it says it doesn't find package and now I get:

It still doesn't find libnotify despite it being installed but now it also has issues with Qt5Versit....
I saw your issue right before creating making mine, but nothing comes to mind which could help you......are you sure the qml file is being deployed though?

Thank you very much.

sudo apt install libnotify-dev
sudo apt install qt5
sudo apt install qtpim5-dev
sudo apt install lcov
sudo apt install gcovr

but see below app discussion: link, i have a Path problem when launching messaging-app

if you are in a lxd container, need to install trough lxc exec name_of_your_container -- apt install ...

Hi @vadrian89 What would be great from my point of view would be if you could get qtox working on the phone.

I'm not at a point that I can do that, at the moment I'm caught up in a lot of learning.
Besides trying to learn my way through Ubuntu Touch development I am also on an online course for another programming language and with work I stop everything at 22:00.
I have looked at the application you mentioned and from the looks of it, it can be done though a bit hard because it needs a port for the UI, but still I'm not qualified to take a charge on developing it, sorry.
