One other quick thought that came to me, android uses multiple threads/jobs
by default and if I recall correctly we do something special in the java
example (I forget if you are using java or pure native) to make sure the
rendering happens in the right thread. Maybe your function is not calling
render in the right thread? Might be worth a shot. I believe the code we
use is something like the following in
https://gitlab.kitware.com/vtk/vtk/blob/master/Examples/Android/JavaVTK/src/com/kitware/JavaVTK/JavaVTKView.java
// forward events to rendering thread for it to handle public
boolean onKeyUp(int keyCode, KeyEvent event) { final
KeyEvent keyEvent = event; queueEvent(new Runnable()
{ public void run() {
myRenderer.onKeyEvent(false, keyEvent); }
}); return true; }
THanks
