允许录制屏幕未在 android 的应用程序外部显示

Question

我正在开发一个简单的屏幕录制应用程序，它运行良好。 我还创建了一个浮动小部件，当用户打开应用程序以及应用程序在后台运行时会显示该小部件。

当我在应用程序中按下浮动小部件时，每次都会出现下面的对话框，如果我按下是，它将开始录制，我从谷歌播放商店下载的应用程序也会发生同样的情况。

但是当我离开我的应用程序时，如果我再次按下浮动小部件，它不会弹出上面的对话框，而我从 Play 商店下载的应用程序会弹出。而且我注意到我从 Play 商店下载的应用程序的浮动小部件隐藏了显示该权限对话框的更多信息。

这是我的显示浮动小部件的服务类

Answer 1

在 FloatingViewService 中添加foreground service 后，您的服务会更好地运行

但是来自Android 10 there are some restrictions

解决这些问题，您的服务将按照您的要求运作。
