[vtkusers] using vtkOBJReader.h in Android example

[Brian Miller]

Oh, actually I think I fixed the second issue by adding vtkIOGeometry
to VTK-7.0.0/Examples/Android/JavaVTK/CMakeLists.txt
in this section

find_package(VTK COMPONENTS
  vtkIOGeometry
  vtkInteractionStyle
  vtkRenderingOpenGL2
  vtkRenderingFreeType
)
