First, IntroductionBroadcast receiver is a broadcast receiver that receives custom and system anchors. It can also be called a listener.Broadcast intent, like intent, is the medium of communication, and unlike intent, broadcast intent is received by multiple components at the same time.Broadcast intent broadcast mechanism, broadcast sources emit messages, and through AMS (Activity Manager service), multiple

As the name suggests, braodcast receiver is a broadcast receiver. It is similar to the time processing mechanism, but the event processing mechanism is program component-level (for example, the Click Event of a button ), the broadcast event processing mechanism is system-level. We can use intent to start a component, or use the sendbroadcast () method to initiate a system-level event broadcast to transmit m

We described the broadcast mechanism of the Android system, in essence, it is a message subscription/advertisement mechanism, so the first step to use such a message-driven model is to subscribe to the message, and for Android applications, the subscription message is actually a register broadcast receiver, This article explores how the

. registerReceiver. The registered broadcast receiver is equivalent to an anonymous class. Both methods require IntentFIlter. IntentFilter intentFilter = new IntentFilter (); intentFilter. addAction (String); // specify the action for BroadcastReceiver to receive the broadcast registerReceiver (BroadcastReceiver, intentFilter) of the same action ); GENERAL: Register in onStart and cancel unregisterReceiver in onStop Specify the broadcast target Acti

Explanation of Intent in Android (2) Introduction to using Intent to Broadcast events and Broadcast Receiver The first article explains how to use Intent to start new application components. However, they can also use the sendBroadcast method to anonymously broadcast messages between components. As a system-level message transmission mechanism, Intent can send structured messages between processes. Therefor

. SELECTED_ALTERNATIVE" String SENDTO_ACTION action: send a message to the receiver specified by data. "Android. intent. action. SENDTO" String SERVICE_STATE_CHANGED_ACTION broadcast: the telephone service status has changed. "Android. intent. action. SERVICE_STATE" String SETTINGS_ACTION action: displays system settings. Input: none. "

In the first article, we've seen how to use intent to launch new application components, but in fact they can also use the Sendbroadcast method to broadcast messages anonymously between components.As a system-level messaging mechanism, intent can send structured messages between processes. Therefore, the broadcast receiver is implemented to monitor and respond to these broadcast Intent within the application.By using intent to broadcast an event, you

public void onreceive (context context, Inte NT Intent) {String msg = Getresultextras (True). GetString ("Msgkey_b"); Do other processing ...} }Register the broadcast receiver below: Send an ordered broadcast:private void Sendbroadcast () {Intent Intent = new Intent ("Android.intent.action.MY_TEST_BROADCAST"); Intent.putextra ("Key", "Hello receiver."); Sendorderedbroadcast (Intent, "Scot

define the priority for android: priority in 3. Each broadcast receiver receives one by one. data can be interrupted or added in the middle. AbortBroadcast () // interrupt Broadcast GetResultExtras (true). putString ("data", "new data"); // Add data GetResultExtras (true). getString ("data") // receives data Listen to SMS reception 1. The Android system

higher the value, the higher the priority, and the more the first response to the data that can be displayed in the Intent-filter under receiver. Android:name= ". MyReceiver1 " Android:enabled= "true" Android:exported= "true" > Android:enabled= "true" Android:exported= "true" > In addition, when the high-priority onreceive executes, you can invoke Ab

This example describes the Broadcastreceiver (broadcast receiver) usage of the four components of Android programming. Share to everyone for your reference, specific as follows: Here's how to create a broadcast, send a disorderly broadcast and ordered broadcast, listen to SMS and listen for outgoing calls (when we send text messages and make a phone call, the system sends a broadcast and we can intercept t

In essence, the broadcast mechanism of the Android system is a message subscription/publishing mechanism. Therefore, the first step to use this message-driven model is to subscribe to messages. for Android applications, subscribing to a message is actually registering a broadcast receiver. Two registration methods are available: static registration and dynamic re
