如果接收器和过滤器没有在清单中设置，为什么Broadcastreceiver不会收到意图？

工作1：

locationNotific = new Intent(PROXIMITY_STRING);

    lPendingIntent = PendingIntent.getBroadcast(this, 0, locationNotific, PendingIntent.FLAG_CANCEL_CURRENT);


       filter = new IntentFilter(PROXIMITY_STRING); 

     contextOnCreate.registerReceiver(new ProximityIntentReceiver(), filter);

    lm.addProximityAlert(LatitudeE6ForPeox1,LongitudeE6ForPeox1,POINT_RADIUS,-1,lPendingIntent);

在清单1中：

<receiver android:name=".ProximityIntentReceiver">
<intent-filter>
<action  android:name="SendProximityIntent">
</action>           
</intent-filter>
</receiver>

工作2：

filter = new IntentFilter(PROXIMITY_STRING); 

         contextOnCreate.registerReceiver(new ProximityIntentReceiver(), filter);

          sendBroadcast(locationNotific);//working becouse of that (dosent work just with proximity)

Dosent Working：

    identif=Long.toString(id);
    locationNotific = new Intent(PROXIMITY_STRING + identif);

    lPendingIntent = PendingIntent.getBroadcast(this, 0, locationNotific, PendingIntent.FLAG_CANCEL_CURRENT);



       filter = new IntentFilter(PROXIMITY_STRING + identif); 

     contextOnCreate.registerReceiver(new ProximityIntentReceiver(), filter);

    lm.addProximityAlert(LatitudeE6ForPeox1,LongitudeE6ForPeox1,POINT_RADIUS,-1,lPendingIntent);
