Overview

The following code snippet demonstrates how to identify the platform version of the device using Java ME.

The platform version can be retrieved just like any system property using the method System.getProperty. The method returns a string containing the specified property.

Source

/**
 * Executes the snippet.
 * Gets platform version and prints it to the log.
 */
private void executeSnippet() {
    String platformVersion = System.getProperty("microedition.platform");
    if (platformVersion != null) {
        printString("Version: " + platformVersion);
    } else {
        printString("Version NOT found!");
    }
}

Postconditions

The platform version is displayed on the screen.
