BroadcastReceiver 를 등록하기 위해선

extends BroadcastReceiver 된 클래스와

manifest에 receiver에 등록 해주어야 한다.

===========================================================================================================================

Manifest 설정

<!-- BroadcastReceiver 액티비티 -->

    <activity android:name.BroadCastReceiverActivity" android:label="" />

     <!-- manifest에 receiver 등록하기

클래스명을 적어준다.-->

        <receiver android:name=".BroadCastReceiverEx">

            <intent-filter>

                <action android:name="mrsohn.samplecode.FIRE"></action>

            </intent-filter>

        </receiver> 

** manifest에 등록 하지 않고
자바 코드로 BroadcastReceiver 등록할 수도 있다.

 IntentFilter filler =
         new IntentFilter("mrsohn.samplecode.FIRE"); //BroadcastReceiver의 action 값 

//BroadcastReceiver 클래스 
BroadCastReceiverEx r = new BroadCastReceiverEx();  
//등록하기       
registerReceiver(r, iller);             

//해제할 때는
unregisterReceiver(receiver);
