I didn't see an analysis of the structure of the Android software, only some low level statistics. Why should we care that the command line parsing code is all put in a single C function? The question is whether it is generated code or not? More than the size of files or of methods, the architecture of the classes and data structures, their coupling or lack of, etc,p is what matters for understanding and maintaing a big software system.
