[Development] Error in running Qt3D app

[Svenn-Arne Dragly]

Hi,

Are you trying to run the example on Android? If so, try to make a 
simple Qt3D example with a QML Scene3D object, like this: 
https://doc.qt.io/qt-5/qt3d-scene3d-example.html

I have had some trouble with running the other Qt3D examples on Android, 
but I have not seen the same error message as you got. It has often 
helped to run it through a Scene3D object, however. This is of course 
only a long term solution if you are working on a QML project. But, 
testing the example will give you a good indication of whether Qt3D in 
general works on your device or not. If not, there might be some issue 
with getting access to an OpenGL context on your device. Then I would 
try to find a simple OpenGL example for Android in Java just to check.


Cheers,

Svenn-Arne
