Monitoring incoming SMS messages in Android

I have this program that will try to monitor incoming SMS messages. But when I tried to run my program in the emulator and I tried to send a SMS message, it works. But when I installed my program in my phone, its not working.

What is the problem?

And I want to run the program at the backend as well. How to do that?

BTW, below are the whole codes for this sample app.

Thanks

import java.io.BufferedWriter;
import java.io.FileWriter;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;

public class MySMSMonitor extends BroadcastReceiver
{
    private static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";

    @Override 
    public void onReceive(Context context, Intent intent) 
    {
        if(intent!=null && 
                intent.getAction()!=null && 
                ACTION.compareToIgnoreCase(intent.getAction())==0)
        {
            Object[]pduArray= (Object[]) intent.getExtras().get("pdus");
            SmsMessage[] messages = new SmsMessage[pduArray.length];

            for (int i = 0; i<pduArray.length; i++) {
                messages[i] = SmsMessage.createFromPdu ((byte[])pduArray [i]); 
            }
            Log.d("MySMSMonitor","SMS Message Received.");
        }
    }
}

I would simply insist you to use ContentObserver and register content://sms Uri and fetch the type of the SMS using 

cusor.getString(cusor.getColumnIndex("type")); // 1 = SMS Received 
                                               // 2 =  SMS Sent

Further you can easily get the required data from the cursor that you fetched. Here is a blog for the same.

Try This:

<receiver android:name=".MySMSMonitor"
              android:permission="android.permission.BROADCAST_SMS">

      <intent-filter android:priority="2">
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
      </intent-filter>
    </receiver>

I'm going to assume with the little detail you have provided that the reason it works on a emulator and not your actual phone; may be another conflicting app intercepting the messages before they are broadcasted to your app.

try adding android:priority="1000" to your intent-filter of your receiver in your apps manifest (a thousand being whatever number you feel necessary, could be higher if needed) 

<intent-filter android:priority="1000" >
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>

more info on - intent-filter priority
