First thank you for this interesting and complete book.
I actually having some problem with the code p38.
String vertexShaderSource = TextResourceReader .readTextFileFromResource(context, R.raw.**simple_vertex_shader**);
String fragmentShaderSource = TextResourceReader
The ** ** part are underline in red saying that it “cannot be resolved or is not a field”, I have go on the project until I have to test the project, but now I can’t with this problem. I have also donwload the source code but I am facing the same problem. What can I do?
Thank you for your help.
