<div dir="ltr">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 <div><br></div><div><a href="https://gitlab.kitware.com/vtk/vtk/blob/master/Examples/Android/JavaVTK/src/com/kitware/JavaVTK/JavaVTKView.java">https://gitlab.kitware.com/vtk/vtk/blob/master/Examples/Android/JavaVTK/src/com/kitware/JavaVTK/JavaVTKView.java</a> <br></div><div><br></div><div><pre class="" style="font-family:Menlo,'Liberation Mono',Consolas,'DejaVu Sans Mono','Ubuntu Mono','Courier New','andale mono','lucida console',monospace;padding:10px;margin-top:0px;margin-bottom:0px;word-wrap:normal;border-left-width:1px;border-style:none none none solid;border-left-color:rgb(220,224,230);border-radius:0px;font-size:13px!important;line-height:1.5!important;color:rgb(51,51,51)!important"><code style="font-family:Menlo,'Liberation Mono',Consolas,'DejaVu Sans Mono','Ubuntu Mono','Courier New','andale mono','lucida console',monospace;font-size:inherit;padding:0px;color:inherit;border-radius:0px;word-wrap:normal;background-color:transparent"><span id="LC287" class="" style="display:inline"> <span class="" style="color:rgb(153,153,136);font-style:italic">// forward events to rendering thread for it to handle</span></span>

The "error setting attribute" type problems stem from either the shader not actually using the passed attribute or attempting to set the attribute with no data. Looking at the shader the attributes are definitely being used which means the error is maybe due to somehow setting the attribute with no data. Maybe somehow the mapper is not setup yet when your new method is getting called?
