黑莓7开发入门？

Question

有人可以为我指出学习Blackberry 7开发方法的正确方向吗？

实际上，我需要的只是实现推送通知并仅打开Web URL。

我看到该平台有不同的框架，例如webWorks等。

我有点困惑，但是我不想写Javascript或HTML或CSS。

我想编写本机代码，以实现推送并向我加载我已经拥有的外部URL。

关于此的任何教程或一些信息都将很棒:)

尝试这个 -

Client side code -

// Main Class-
class App extends UiApplication {
 private static App theApp;
  public App() {
       pushScreen(new register());    
    }

  public static void main(String[] args) {
          if (args.length > 0 && args[0].equals("BB_push") ){
             theApp = new App();
             theApp.enterEventDispatcher();   

            }
        else {      
            BackgroundApplication backApp=new BackgroundApplication();
            backApp.setupBackgroundApplication();
            backApp.enterEventDispatcher();

       }       
    }  
}




//Register Class-
public class register extends MainScreen{
    public register(){
    final ButtonField btn=new ButtonField("Register");
        add(btn);
 FieldChangeListener listener=new FieldChangeListener() {
               public void fieldChanged(Field field, int context) {

                   if(field==btn){

                     registerBpas();

                   }

               }};
    btn.setChangeListener(listener);

}
}
