BroadcastReceiver는 onReceive 메소드를 호출하지 않습니다.

Question

주요 활동에서 어떤 라디오 버튼이 눌러져 있는지에 따라 ITelephony를 사용하여 호출을 차단하는 앱을 만들려고합니다. 그러나, 내 onReceive 메서드를 호출 한 적이 있으므로 호출을 차단하지 않습니다. 여기

public class CallBlocking extends BroadcastReceiver { 
     private static final int MODE_WORLD_READABLE = 1; 
     private String mPhoneNumber; 
     private String mCallerName; 
     private SharedPreferences mPreferences; 


     @Override 
     public void onReceive(Context context, Intent intent) { 
      mPreferences = context.getSharedPreferences("mPreferences", MODE_WORLD_READABLE); 
      String blockMode = mPreferences.getString("mode", "not retrieved"); 
      if (!blockMode.equals("cancel")) { 
       Bundle b = intent.getExtras(); 
       String phoneState = b.getString(TelephonyManager.EXTRA_STATE); 
       if ((phoneState.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))) { 
        mPhoneNumber = b.getString(TelephonyManager.EXTRA_INCOMING_NUMBER); 
        if (blockMode.equals("all")) { 
         disconnect(context); 
        } else if (blockMode.equals("unsaved")) { 
         mCallerName = getContactName(mPhoneNumber, context); 
         if((mCallerName == null) || (mCallerName.length() < 2)) 
          disconnect(context); 
         else if (blockMode.equals("list")) 
         { 
          if(CallBlockerFragment.sBlockedList.contains(new BlockedList(mPhoneNumber))) 
           disconnect(context); 
         } 
        } 
       } 
      } 
     } 

     @SuppressWarnings({"rawtypes", "unchecked"})

      ITelephony telephonyService; 
      TelephonyManager telephony = (TelephonyManager)

      try { 
       Class c = Class.forName(telephony.getClass().getName()); 
       Method m = c.getDeclaredMethod("getITelephony"); 
       m.setAccessible(true); 
       telephonyService = (ITelephony) m.invoke(telephony); 
       telephonyService.endCall(); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     } 

     public String getContactName(String phoneNumber, Context context) { 
      Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber)); 
      String callerName = "?"; 
      String data = null; 
      ContentResolver contentResolver = context.getContentResolver(); 
      Cursor findContact = contentResolver.query(uri, new String[] {BaseColumns._ID, 
       ContactsContract.PhoneLookup.DISPLAY_NAME}, null, null, null); 

      try { 
       if (findContact != null && findContact.getCount() > 0) { 
        findContact.moveToNext(); 
        data = findContact.getString((findContact.getColumnIndex(ContactsContract.Data.DISPLAY_NAME))); 
       } 
      } 
      finally 
      { 
       if(findContact != null) 
        findContact.close(); 
      } 

      return data;

</manifest> 

이유는 onReceive 메서드를 호출되지이다?
