DevEco Studio和系统升级后，EntryAbility.ets文件创建悬浮窗失败

在DevEco Studio和系统升级前，在EntryAbility.ets文件可以创建悬浮窗，升级到最新的之后创建失败。

代码如下：

let floatWindowClass: window.Window | null = null; 
// 1.创建悬浮窗 
const config: window.Configuration = { 
  name: "floatWindow", windowType: window.WindowType.TYPE_FLOAT, ctx: this.context 
}; 
window.createWindow(config, (err: BusinessError, data) => { 
  let errCode: number = err.code; 
  if (errCode) { 
    console.error('floatWindowClass Failed to create the floatWindow. Cause: ' + JSON.stringify(err)); 
    return; 
  } 
  console.info('floatWindowClass Succeeded in creating the floatWindow. Data: ' + JSON.stringify(data)); 
  { 
    let errCode: number = err.code; 
    if (errCode) { 
      console.error('floatWindowClass Failed to create the floatWindow. Cause: ' + JSON.stringify(err)); 
      return; 
    } 
    console.info('floatWindowClass Succeeded in creating the floatWindow. Data: ' + JSON.stringify(data)); 
    floatWindowClass = data; 
    AppStorage.setOrCreate('floatWindowClass', floatWindowClass); 
    // 2.悬浮窗窗口创建成功后，设置悬浮窗的位置、大小及相关属性等。 
    floatWindowClass.moveWindowTo(0, 604, (err: BusinessError) => { 
      let errCode: number = err.code; 
      if (errCode) { 
        console.error('floatWindowClass Failed to move the window. Cause:' + JSON.stringify(err)); 
        return; 
      } 
      console.info('floatWindowClass Succeeded in moving the window.'); 
    }); 
    // 3.为悬浮窗加载对应的目标页面。 
    floatWindowClass.setUIContent("pages/view/AudioComponent", (err: BusinessError) => { 
      let errCode: number = err.code; 
      if (errCode) { 
        console.error('floatWindowClass Failed to load the content. Cause:' + JSON.stringify(err)); 
        return; 
      } 
      console.info('floatWindowClass Succeeded in loading the content.'); 
    }); 
 
    floatWindowClass.on('windowEvent', (data) => { 
      EmitterUtils.sendEvent(EmitterEventId.AUDIO_WINDOW_TYPE, data) 
    }); 
  })
