Hi,

I want to run vtk on android.  
I build vtk9.2.2 with ndk 25 on ubuntu.  
I try to run the official example NativeVTK.  
But I get black screen.  
Similar with

> [@VTK8.2.0(& VTK 9.1.0) for android with official Android's example(JavaVTK) not runing exactly](https://discourse.vtk.org/t/vtk8-2-0-vtk-9-1-0-for-android-with-official-androids-example-javavtk-not-runing-exactly/7622):

> Hello everyone, I was already build VTK 8.2.0 and VTK 9.1.0 with ndk-r21e and import it into AndroidStudio. I was created 2 projects that one include VTK-8.2.0 and the other include VTK-9.1.0 , and I copy the code which from github(Java and c++ source code) into the AndroidStudio. in project \<VTK 8.2.0\> ,it was crashed immediately, I found it is because vtkRenderWindow::New() return Null! in project \<VTK 9.1.0\>, it was not crash,but only black screen!

Is vtk9.2.2 to new and not compatible with the newest android?

Thanks!

VTK hasn’t had much attention put into Android support recently, so it certainly could have slipped some.

We have been building it over at [GitHub - f3d-app/f3d: Fast and minimalist 3D viewer.](https://github.com/f3d-app/f3d/), but I think adding a CI in VTK would be a nice improvement for everyone.
