FileConnection API

On a real device, the FileConnection API typically provides access to files stored in the device’s memory or on a memory card.

In the Java ME Platform SDK emulator, the FileConnection API enables MIDlets to access files stored on your computer’s hard disk.

The files that can be accessed using FileConnection are stored in the following subdirectory:


Documents and Settings\User\Application Support\javame-sdk\3.0\work\emulator-instance\appdb\filesystem

Mac OS

User/Application Support/javame-sdk/3.0/work/emulator-instance/appdb/filesystem

For example, the DefaultCldcPhone1 emulator instance comes with a root directory installed called root1, which contains a Readme file and an empty directory named photos.

Each subdirectory of filesystem is called a root. The Java ME Platform SDK provides a mechanism for managing roots. While the emulator is running, choose View > External Events Generator from the emulator window’s menu. A utility window opens. Click the File Connection tab.

In the File Connection panel you can mount, unmount, or delete filesystem roots. Mounted roots are displayed in the top list, and unmounted roots are moved to the bottom list. Mounted root directories and their subdirectories are available to applications using the FileConnection API. Unmounted roots can be remounted in the future.
