But i did not find anything about some kind of provider as you describe in your post. 但是，正如您在帖子中所描述的，我没有找到有关某种提供商的任何信息。

It looks like there is a dedicated service running from android 4.0 and up which helps to take screenshots by the way you have mentioned here. 似乎有一个从android 4.0开始运行的专用服务，该服务可通过您在此处提到的方式来帮助截取屏幕截图。

But I am not aware of how it happens in the previous versions of android. 但是我不知道它在以前的android版本中是如何发生的。

Here is a link to the Service TakeScreenshotService . 这是服务TakeScreenshotService的链接。 When you look into it you will be able to see another class which actually is responsible for capturing the Screenshot and storing it. 当您查看它时，您将能够看到另一个类，该类实际上负责捕获屏幕快照并进行存储。 And here is the link to the class GlobalScreenshot. 这是指向GlobalScreenshot类的链接。
