问题描述

我想从后台应用程序打开我的 UI 应用程序.它是怎么做的?.

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
   }
}

当我收到推送通知时,BackgroundApplication 应该会提醒一个弹出窗口.当我单击弹出窗口时,我希望它打开 UI 屏幕.这是怎么做的?我试过这个:

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();
     }

但它没有打开用户界面.

But it's not opening the UI.

推荐答案

您应该将参数MYAPP"传递给正在运行应用程序的代码:

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);
