PACKAGE_REPLACED如何在android中运行?

标签: android broadcastreceiver package

我希望运行一项服务,只要我的应用在用户的设备中更新,我就会使用PACKAGE_REPLACED接收器来触发服务,同时还会显示一个toast来测试应用是否获得接收器事件或不。但吐司只在我启动应用程序后才显示,而不是在应用程序更新时。所以我的问题是:

  1. 当app未更新时,是否可以触发事件?因为toast需要应用程序上下文,这就是为什么它会在应用程序启动时触发showToast()?
  2. 是否需要在以前的版本中处理PACKAGE_REPLACED接收器,那么只有它可以工作?只是想知道PACKAGE_REPLACED的流程。
  3. 清单文件
