实现BroadcastReceiver即服务 - Android

Question

我想实现一旦安装它就永远不会被终止的应用程序，并监视收到的每个收到的SMS。

我想在我的应用程序中实施服务，它拥有BroadcastReciever的实例。

你能帮我通过一个例子来实现吗？为了达到这个目的，这是否是正确的OOD？

Thx !!

1.您的解决方案仅适用于您。没有服务是没有被系统杀死的。

2.You需要一个箱子到BroadCastReciver读取每个传入消息。请看看下面的代码注册传入SMS读取器类，清单

3.当您收到的BroadCastReciver触发您需要从BroadCastReciver和通呼叫服务SMS要进一步处理的服务数据。

4.这样你就不用担心服务被System杀死了。

为AndroidManifest.xml文件完整代码：

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.androidexample.broadcastreceiver" 
    android:versionCode="1"

IncomingSms.java文件的详细信息：

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); 

}
