Android source code Analysis--BroadcastBroadcasting is a way of delivering messages between components. The implementation of broadcasting mechanism is based on the binder interprocess communication.Binder interprocess communication and broadcast differences: In binder, the client component and service component must first obtain a proxy object for the service before the client component has to know the presence of the service component beforehand. The broadcast sender is not aware of the presen

Broadcastreceiver (broadcast receiver) is one of the four main components in Android.
The following is an overview of broadcastreceiver in Android DOC:① A broadcast receiver is a component that focuses on receiving and processing broadcast notifications. Many broadcasts originate from system code, such as notifying time zone changes, low battery, taking a picture, or changing language options. Applications

Introduction to Broadcast Receiver
Broadcast Receiver is one of the five major Android components and is frequently used.
It is used to receive broadcast Intent asynchronously. The broadcast Intent is sent by calling Context. sendBroadcast () and BroadcastReceiver are used to receive broadcast Intent asynchronously. sendBroadcast (), Context. sendOrderedBroadcast () or Context. sendStickyBroadcast. General
When a situation occurs on an Android system, all programs must be notified of processing, such as low power, and the broadcast intent object can be used to broadcast information.The operating mechanism consists of two parts: The program that sends out the intent object, the program that listens to the broadcast information (broadcast Receiver), its province is a class, must inherit the Broadcastreceiver class, must register with the system, and speci

Now Citrix's support for mobile phones is getting better, and currently supports Windows mobile operating systems, java,android,iphone operating systems.
It also supports the more popular ipod Touch,ipad at the moment.
Allows users to work through the phone anytime, anywhere, wherever you can,
is validating the famous quote from Citrix.
"A World anyone can work anywhere".
