String android.content.Intent.ACTION_PACKAGE_ADDED = "android.intent.action.PACKAGE_ADDED"

Broadcast Action: A new application package has been installed on the device. The data contains the name of the package. Note that the newly installed package does not receive this broadcast.

My include the following extras:

* EXTRA_UID containing the integer uid assigned to the new package.
* EXTRA_REPLACING is set to true if this is following an ACTION_PACKAGE_REMOVED broadcast for the same package.

This is a protected intent that can only be sent by the system

----------

当系统中新安装了一个软件或重新安装一个软件都会触发这个action的广播，
并发送intent给接收者，发送的intent中包话新安装应用的包名、系统指定给这个应用的ID、标识是否这个广播是在ACTION_PACKAGE_REMOVED广播发送之后发送的。

这种广播只能系统来发送。
