Browsing Files

To run the file browser, you’ll need to give the MIDlet appropriate security authorization, if you have not already done so. Right-click on your project, choose Properties, and select Specify the Security Domain. If necessary, select the maximum domain and press OK.

Now open and run the PDAPDemo project. Launch the FileBrowser MIDlet. You see a directory listing, and you can browse through the available directories and files. By default there is one directory, root1. This directory is located at USER_HOME/javame-sdk/3.0/work/emulator-instance/appdb/filesystem/root1.

Select the directory and press the View soft button to enter it.

The directories photos and private are empty by default. You can add files and root directories and they will be visible to the JSR 75 File API. See JSR 75: PDA Optional Packages for more information. (This demo shows a README and some JPEGs that were added to the local photos directory.)

Using the Menu commands you can view a file or see its properties. Try selecting the file and choosing Properties or View from the menu. Here we view README.txt:
