在HarmonyOS NEXT开发中应用手动退到后台？

Answer 1

窗口里有minimize方法，这个接口会通知ams窗口退后台，来实现app回到后台的效果 参考链接：https://developer.huawei.com/consumer/cn/doc/harmonyos-refere...
目前windowStage只在onWindowStageCreate中存在。获取需要使用AppStorage。参考代码：

onWindowStageCreate(windowStage: window.WindowStage): void { 
  // Main window is created, set main page for this ability 
  hilog.info(0x0000, ‘testTag’, ‘%{public}s’, ‘Ability onWindowStageCreate’); 
 
windowStage.loadContent(‘pages/Page6’, (err, data) => { 
 
  if (err.code) { 
    hilog.error(0x0000, ‘testTag’, ‘Failed to load the content. Cause: %{public}s’, JSON.stringify(err) ?? ‘’); 
    return; 
  } 
  AppStorage.setOrCreate(“windowStage”,windowStage); 
 
  hilog.info(0x0000, ‘testTag’, ‘Succeeded in loading the content. Data: %{public}s’, JSON.stringify(data) ?? ‘’); 
}); 
}
