Introductory knowledge
What is broadcasting?
Broadcasting is a mechanism provided by the Android system to transmit events or messages in the system. Broadcasting can be at the system level or at the application level. System-level broadcasts can be received by all applications, and application-level broadcasts can only be received by components in the same application.
Classification of Broadcasting
There are two types of broadcasts: standard broadcasts and ordered broadcasts.
Standard broadcast: The sender cannot know whether the receiver has received the broadcast, nor can the receiver know the processing order of the receiver. Standard broadcast is an asynchronous broadcast, and all receivers receive the broadcast at the same time.
Ordered broadcast: The sender can know whether the receiver has received the broadcast, and can also specify the processing order of the receiver. Ordered broadcast is a synchronous broadcast, each receiver receives the broadcast in order of priority, and can terminate the delivery of the broadcast.
sending of broadcast
Sending a broadcast can be simulated using the adb shell command. The command format is as follows:
adb shell am broadcast -a <action> [-d ] [-t <mime_type>] [-c <category> [-c <category>] ...]
Among them, -athe parameter specifies the Action of the broadcast, -dthe parameter specifies the Data URI of the broadcast, -tthe parameter specifies the MIME type of the broadcast, and -cthe parameter specifies the Category of the broadcast.
