如何从设备获取新的短信？

Question

我一直在开发应用程序，我需要处理文本的正文。我尝试使用BroadcastReceiver它：

private static final Uri SMS_INBOX_URI = Uri.parse("content://sms/inbox"); 

@Override 
public void onReceive(Context context, Intent intent) { 
    // TODO Auto-generated method stub 
    SharedPreferences prefs=PreferenceManager.getDefaultSharedPreferences(context); 

    Cursor sms = context.getContentResolver().query(SMS_INBOX_URI, null, null, null, null); 
    sms.moveToFirst(); 

    String body=sms.getString(sms.getColumnIndex("body")); 
    String number=sms.getString(sms.getColumnIndex("address")); 
    String key=prefs.getString(context.getString(R.string.acc_key_key), ""); 
    sms.close(); 
    Log.e("body", body); 
    if (body.trim().equals("#"+key)) { 
     Log.e("sms", "sending"); 
     sendGPSCoordinates(context, number); 
    } else if (body.trim().equals("?"+key)){ 
     Log.e("request", "manual"); 
     sendResponces(context); 
    } 
} 

但这个代码返回最后的短信，而不是一个新的SMS。但我需要收到新的短信。我该怎么做？

要收到短信一个非常非常goood教程HERE

@Override 
    public void onReceive(Context context, Intent intent) 
    { 
     //---get the SMS message passed in--- 
     Bundle bundle = intent.getExtras();   
     SmsMessage[] msgs = null; 
     String str = "";    
     if (bundle != null) 
     { 
      //---retrieve the SMS message received--- 
      Object[] pdus = (Object[]) bundle.get("pdus"); 
      msgs = new SmsMessage[pdus.length];    
      for (int i=0; i<msgs.length; i++){ 
       msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);     
       str += "SMS from " + msgs[i].getOriginatingAddress();      
       str += " :"; 
       str += msgs[i].getMessageBody().toString(); 
       str += "\n";   
      } 
      //---display the new SMS message--- 
      Toast.makeText(context, str, Toast.LENGTH_SHORT).show(); 
     }       
    }

请更改以下行，

Cursor sms = context.getContentResolver().query(SMS_INBOX_URI, null, null, null, null); 
sms.moveToFirst(); 

来，像下面，

Cursor sms = context.getContentResolver().query(SMS_INBOX_URI, null, null, null, null); 
sms.moveToLast(); // Moving to newly received SMS
