實現BroadcastReceiver即服務 - Android

Question

我想實現一旦安裝它就永遠不會被終止的應用程序，並監視收到的每個收到的SMS。

我想在我的應用程序中實施服務，它擁有BroadcastReciever的實例。

你能幫我通過一個例子來實現嗎？爲了達到這個目的，這是否是正確的OOD？

Thx !!

1.您的解決方案僅適用於您。沒有服務是沒有被系統殺死的。

2.You需要一個箱子到BroadCastReciver讀取每個傳入消息。請看看下面的代碼註冊傳入SMS讀取器類，清單

3.當您收到的BroadCastReciver觸發您需要從BroadCastReciver和通呼叫服務SMS要進一步處理的服務數據。

4.這樣你就不用擔心服務被System殺死了。

IncomingSms.java文件的詳細信息：

I have made broadcast event reciever in this file 

1. Created class IncomingSms with extends BroadcastReceiver class 



public class IncomingSms extends BroadcastReceiver 


     2. Get the object of SmsManager to find out received sms details 



// Get the object of SmsManager 
final SmsManager sms = SmsManager.getDefault(); 


     3. Create method receiver() 



public void onReceive(Context context, Intent intent) 


     4. Get/Read current Incomming SMS data 



// Retrieves a map of extended data from the intent. 
final Bundle bundle = intent.getExtras(); 

try { 

    if (bundle != null) { 

     final Object[] pdusObj = (Object[]) bundle.get("pdus"); 

     for (int i = 0; i < pdusObj.length; i++) { 

      SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]); 
      String phoneNumber = currentMessage.getDisplayOriginatingAddress(); 

      String senderNum = phoneNumber; 
      String message = currentMessage.getDisplayMessageBody(); 

      Log.i("SmsReceiver", "senderNum: "+ senderNum + "; message: " + message); 


      // Show alert 
      int duration = Toast.LENGTH_LONG; 
      Toast toast = Toast.makeText(context, "senderNum: "+ senderNum + ", message: " + message, duration); 
      toast.show(); 

     } // end for loop 
     } // bundle is null 

} catch (Exception e) { 
    Log.e("SmsReceiver", "Exception smsReceiver" +e); 

}
