How to find mobile OS name and OS version using Java-ME?

I 开发者_JS百科need to find mobile OS name and OS version programmatically: like Symbian s40 3rd edition or 5th edition. How to achieve this in J2ME?

---

System.getProperty("microedition.platform"); It will return something like Nokia6310i/4.42.

See http://www.developer.nokia.com/Community/Discussion/showthread.php?86604-j2me-system-properties

I am not sure it is exactly what you need but this is what I can offer you.

You can also detect features programatically. Query the microedition.platform to see if it's a Nokia. Then, check for the existence of APIs which distinguish the versions you are interested in. E.g., to check whether the Location API JSR179 is present:

boolean hasJSR179 = false;
try {
    Class.forName("javax.microedition.location.LocationException");
    hasJSR179 = true;
} catch (ClassNotFoundException e) { /* no JSR 179 */ }
