黑莓聲音配置文件變更/音量變更監聽器

我想製作監聽黑莓聲音配置文件變更/音量變更的應用程序。目標版本是5,6,7 我在黑莓的文檔中搜索，但什麼也沒找到。我在搜索過程中發現了兩件事。黑莓聲音配置文件變更/音量變更監聽器

globaleventlistener 這需要一個事件的GUID，這個事件是不是在事件列表GUID documented。
通知管理器 Notificationmanager可能會幫助其中一個註冊表。但我不知道如何註冊系統事件。它也需要GUID。

請分享資源，如果我錯過了什麼。我是黑莓開發的新手。請幫助我。

感謝， PARTH沙阿

這應該處理你們在找什麼。作爲自定義keyListner：

public final class Logger implements KeyListener { 
//Set return to false to allow the program to pass the data to next keylistner 
//All output to the console. 
//Yet from testing only KeyUp and KeyDown are ever called and handle all special buttons 
//Volume, Dial, EndCall, etc...

     System.out.println("CHAR PRESSED: <"+key+"/>"); 
     return false;
