Organizing a Virtual Filesystem

by Sergey Kosarevsky Viktor Latypov | November 2013 | Cookbooks Open Source

This article has written by Sergey Kosarevsky and Viktor Latypov, the authors of the book Android NDK Game Development Cookbook is devoted entirely to the asynchronous file handling, resource proxies, and resource compression. Many programs store their data as a set of files. Loading these files without blocking the whole program is an important issue. Human interface guidelines for all modern operating systems prescript the application developer to avoid any delay, or "freezing", in the program's workflow (known as the Application Not Responding (ANR) error in Android).

In this article we will cover:

  • Abstracting file streams
  • Implementing portable memory-mapped files
  • Implementing file writers
  • Working with in-memory files
  • Implementing mount points
  • Enumerating files in the .zip archives
  • Decompressing files from the .zip archives
  • Loading resources asynchronously
  • Storing application data
