Android uses two ways of registering receiver

1.

Package Com.example.myreceiver;import Android.os.bundle;import Android.app.activity;import android.content.Intent; Import Android.content.intentfilter;import Android.view.menu;import Android.view.view;public class MainActivity Extends Activity {private Mybroadcastreceiver receiver = new Mybroadcastreceiver ();p rivate intentfilter filter = new Inten Tfilter ("Com.feng.intent"); @Overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate ( Savedinstancestate); Setcontentview (R.layout.activity_main);} @Overridepublic boolean Oncreateoptionsmenu (Menu menu) {//Inflate the menu; This adds items to the action bar if it is PR Esent.getmenuinflater (). Inflate (R.menu.main, menu); return true;} public void Start (view view) {Intent Intent = new Intent ("Com.feng.intent"); Intent.putextra ("Name", "Wang"); Sendbroadcast (intent);} @Overrideprotected void OnPause () {super.onpause (); Unregisterreceiver (receiver);} @Overrideprotected void Onresume () {super.onresume (); Registerreceiver (receiver, filter);}}

Package Com.example.myreceiver;import Android.content.broadcastreceiver;import Android.content.context;import Android.content.intent;import Android.util.log;public class Mybroadcastreceiver extends broadcastreceiver{@ overridepublic void OnReceive (Context arg0, Intent arg1) {System.out.println ("Good!i ' ve recevied u!"); LOG.E ("Mybroadcastreceiver", "Good!i ' ve recevied u!");}}

The advantage of this approach is that it is flexible to use and highly controllable.

Another is to register in the Mainfest.xml. The benefit is that as long as the application is installed, it will remain in the listening state.

      <receiver android:name= "Com.example.myreceiver.MyBroadcastReceiver" >            <intent-filter >                < Action android:name= "com.feng.intent"/>            </intent-filter>        </receiver>
