黑莓备用入口点 - 开始从后台应用程序（推送邮件点击）应用 [英] blackberry alternate entry point- start app from background application(on push message click)

问题描述

我想从一个后台应用程序中打开我的UI应用程序。如何做？

I want to open my UI app from a background application. How its done ?.

public static void main(String[] args) {
   if (args.length > 0 && args[0].equals("MYAPP") ){
      theApp = new App();
      theApp.enterEventDispatcher();  ///this  is my ui class
   }
   else {
      BackgroundApplication app = new BackgroundApplication();
      app.setupBackgroundApplication();
      app.enterEventDispatcher();  ///this is a background application listen for push notifications
   }
}

当我收到推送通知，在 BackgroundApplication 应提醒弹出。
当我点击弹出，我希望它打开UI界面。如何做到这一点？我想这样的：

When I get a push notification, the BackgroundApplication should alert a popup. When I click the popup, I want it to open the UI screen. How is this done? I tried this:

int modHandle = CodeModuleManager.getModuleHandle("MYAPP");
     ApplicationDescriptor[] apDes = CodeModuleManager.getApplicationDescriptors(modHandle);
     try {
        ApplicationManager.getApplicationManager().runApplication(apDes[0]);
     } catch (ApplicationManagerException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
     }

但它不开放的用户界面。

But it's not opening the UI.

推荐答案

您应该通过参数MYAPP对正在运行的应用程序code：

You should pass argument "MYAPP" to code that's running application:

ApplicationDescriptor[] appDescriptors =
CodeModuleManager.getApplicationDescriptors(
        CodeModuleManager.getModuleHandle("MYAPP"));//.Cod file name
ApplicationDescriptor appDescriptor = new ApplicationDescriptor(
appDescriptors[0], new String[] {"MYAPP"});
ApplicationManager.getApplicationManager().runApplication(appDescriptor);
