如何在意向登記服務廣播接收器

Question

我有下面的代碼這給通過非法參數異常

public class CheckServer extends IntentService 
{ 

public String snumber; 

public CheckServer() 
{ 
    super("CheckServer"); 
} 


@Override 
public void onCreate() 
{ 
    super.onCreate(); 

    String DELIVERED = "SMS_DELIVERED"; 

    DeliveryReceiver dReceiver = new DeliveryReceiver(); 

    registerReceiver(dReceiver,new IntentFilter(DELIVERED)); 

} 

@Override 
public void onDestroy() 
{ 
    super.onDestroy(); 

    DeliveryReceiver dReceiver = new DeliveryReceiver(); 

    unregisterReceiver(dReceiver); 
    dReceiver = null; 
} 


@Override 
protected void onHandleIntent(Intent intent) 
{ 
    try 
    { 
    serviceAction(); 
    } 
    catch (ClientProtocolException e) 
    { 
    e.printStackTrace(); 
    } 
    catch (IOException e) 
    { 
    e.printStackTrace(); 
    } 
    catch (URISyntaxException e) 
    { 
    e.printStackTrace(); 
    } 
    catch (JSONException e) 
    { 
    e.printStackTrace(); 
    } 

    scheduleNextUpdate(); 
} 

private void scheduleNextUpdate() 
{ 
    Intent intent = new Intent(this, this.getClass()); 
    PendingIntent pendingIntent = 
    PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 

    long currentTimeMillis = System.currentTimeMillis(); 
    long nextUpdateTimeMillis = currentTimeMillis + 1 * DateUtils.MINUTE_IN_MILLIS; 
    Time nextUpdateTime = new Time(); 
    nextUpdateTime.set(nextUpdateTimeMillis); 

    AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 
    alarmManager.set(AlarmManager.RTC, nextUpdateTimeMillis, pendingIntent); 
} 

public void serviceAction() throws ClientProtocolException, IOException, URISyntaxException, JSONException 
{ 
    HttpResponse response = null; 
    HttpClient client = new DefaultHttpClient(); 
     HttpGet request = new HttpGet(); 
     request.setURI(new URI("http://www.examplecom/sms/getsms")); 
     response = client.execute(request); 

     String result = convertStreamToString(response.getEntity().getContent()); 

     String no,message; 

     JSONArray array = new JSONArray(result); 

     for (int i = 0; i < array.length(); i++) 
     { 
     JSONObject row = array.getJSONObject(i); 
     snumber = row.getString("sno"); 
     no = row.getString("no"); 
     message = row.getString("message"); 
     sendSMS(no , message); 
     } 
} 

public static String convertStreamToString(InputStream inputStream) throws IOException 
{ 
    if (inputStream != null) 
    { 
     Writer writer = new StringWriter(); 

     char[] buffer = new char[1024]; 
     try 
     { 
      Reader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"),1024); 
      int n; 
      while ((n = reader.read(buffer)) != -1) 
      { 
       writer.write(buffer, 0, n); 
      } 
     } 
     finally 
     { 
      inputStream.close(); 
     } 
     return writer.toString(); 
    } 
    else 
    { 
     return ""; 
    } 
} 

public void sendSMS(String number,String message) 
{ 
    String DELIVERED = "SMS_DELIVERED"; 

    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0, 
      new Intent(DELIVERED), 0); 

    SmsManager smsM = SmsManager.getDefault(); 
    smsM.sendTextMessage(number, null, message, null, deliveredPI); 
} 

public class DeliveryReceiver extends BroadcastReceiver 
{  
    @Override 
    public void onReceive(Context context, Intent arg1) 
    { 
       switch (getResultCode()) 
       { 
        case Activity.RESULT_OK: 

         Toast.makeText(getBaseContext(), "SMS delivered",Toast.LENGTH_SHORT).show(); 
         try 
         { 
           updateSMSstatus(snumber); 
         } 
         catch (ClientProtocolException e) 
         { 
           e.printStackTrace(); 
         } 
         catch (URISyntaxException e) 
         { 
            e.printStackTrace(); 
         } 
         catch (IOException e) 
         { 
              e.printStackTrace(); 
         } 

         break; 

        case Activity.RESULT_CANCELED: 

         Toast.makeText(getBaseContext(), "SMS not delivered",Toast.LENGTH_SHORT).show(); 

         break;       
       } 

    } 

    public void updateSMSstatus(String sno) throws URISyntaxException, ClientProtocolException, IOException 
    { 
     HttpResponse response = null; 
     HttpClient client = new DefaultHttpClient(); 
     HttpGet request = new HttpGet(); 
     request.setURI(new URI("http://www.example.com/sms/updatesmsstatus?uname=someone&sno="+sno)); 
     response = client.execute(request); 


    } 
} 

問題未註冊的接收器是我得到一個寄存器沒有收到錯誤，即使我註冊它在onCreate（）方法中，可能是什麼問題？

Answer 1

而是在onCreate()登記和onDestroy()方法註銷的，我改變了sendSMS方法如下：

public void sendSMS(String number,String message,String serialnum) 
{ 
    String DELIVERED = "SMS_DELIVERED"; 

    Intent delivered = new Intent(DELIVERED); 
    delivered.putExtra("MsgNum", serialnum); 
    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0, delivered, 0); 

    registerReceiver(
     new BroadcastReceiver() 
     { 
      @Override 
      public void onReceive(Context context, Intent intent) 
      { 
         switch (getResultCode()) 
         { 
          case Activity.RESULT_OK: 

           Toast.makeText(getBaseContext(), "SMS delivered",Toast.LENGTH_SHORT).show(); 

           updateSMSStatus USS = new updateSMSStatus(); 

           USS.execute(intent.getStringExtra("Msgnum")); 

           break; 

          case Activity.RESULT_CANCELED: 

           Toast.makeText(getBaseContext(), "SMS not delivered",Toast.LENGTH_SHORT).show(); 

           break;       
         } 

        unregisterReceiver(this); 
      } 

     }, 
     new IntentFilter(DELIVERED)); 

    SmsManager smsMngr = SmsManager.getDefault(); 
    smsMngr.sendTextMessage(number, null, message, null, deliveredPI); 

} 

短信交付行動，現觸發，感謝所有。

關於如何區分每個短信的傳遞報告的任何想法？

我不太確定如何在我的service中使用intent.putExtra()方法，並且遞送BroadcastReceiver。

Answer 2

您必須通過與registerReceiver()一起使用的unregisterReceiver()中的BroadcastReceiver對象。你不是。請使用您在Service的數據成員中使用registerReceiver()的BroadcastReceiver，然後使用unregisterReceiver()的同一對象。
