Overview
The Browser class instance implements the browser user interface metaphor and it allows the user to visualize and navigate through HTML documents. This example has also "Back", "Forward", and "Open URL" Commands for navigating to the previous or next session history items and for opening desired html page. The MIDlet uses MobileShell, because it has a possibility to change the status pane size. The following section contains the complete code for compiling and running the example application.
A Browser-MIDlet integration
The custom Browser with the Option menu expanded

Postconditions
When a BrowserMIDlet is opened, a browser window is shown on the screen. The browser will open the URL http://www.google.com.
