7: Working with the Filesystem
7
Working with the Filesystem
WHAT YOU WILL LEARN IN THIS CHAPTER:
- Creating File and FileStream objects
- Resolving file object paths
- Modifying files and directories
- Using browse dialogs
This chapter takes a look at the AIR File System API in depth, again using Flash Builder to take you through related examples. These will help you to build applications that can create or utilize existing data on a user's mobile device, whether that data is an MP3 file found in the device's native media library, or an image file referenced from the photo gallery.
The key aspect of the API is getting to understand the filesystem, learning how to resolve paths to files, and containing folders on the device. This chapter looks at all this in depth.
WARNING For security reasons the AIR File System API is restricted for use in non-browser Flash applications. Bear this in mind if you intend to create browser-based Flash mobile applications. In addition, Google Android and BlackBerry Tablet OS devices require users to grant usage of certain security levels when using the API.
