Is it possible to run Qt 3D with pure C++ on android? All C++ examples, like the basic shape C++ example, got this entry in the .pro file:
android|ios|tvos|winrt {
warning( "This example is not supported for android, ios, tvos, or winrt." )
}
I wrote an app that is very similar to the example but smaller. It's just a Qt3DWindow with one entity and some components. It works on my laptop (Windows 8.1) but it crashes on my AVDs.
I tried some Nexus and Pixel AVDs with APIs ranging from 23 to 25 with software and hardware graphics rendering.
I followed this guide to set up QtCreator 2.3.0 and I'm using Qt 5.9.0-X86-rc. All android examples are running fine.
This is the application output:
