Answer 1

This is what I used to read SMS, download the raw file from gits Android SMS Receive Listener Implement SMSReceivedListner and add it SMSReceiver.addSMSListner(this);

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

import java.util.ArrayList;

/**
 * @@author Chathura Wijesinghe <cdanasiri@gmail.com>

 * <receiver android:name=".SMSReceiver" >
        <intent-filter>
            <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
        </intent-filter>
    </receiver>
 */
public class SMSReceiver extends BroadcastReceiver {

private static final String SMS_RECEIVED         = "android.provider.Telephony.SMS_RECEIVED";

private static ArrayList<SMSReceivedListner> smsListner = new ArrayList<SMSReceivedListner>();

@Override
public void onReceive(Context context, Intent intent) {
    final String action = intent.getAction();
    final Bundle extras = intent.getExtras();


    if (action.equals(SMSReceiver.SMS_RECEIVED)) {
        final boolean smsValid = extras != null;

        if (smsValid) {
            //Create SMSMessages from PDUs in the Bundle
            final Object[] pdus = (Object[])extras.get("pdus");
            final SmsMessage[] messages = new SmsMessage[pdus.length];
            for (int i = 0; i < pdus.length; i++)
                messages[i] = SmsMessage.createFromPdu((byte[])pdus[i]);

            //Assemble
            final ArrayList<Long> vibrations = new ArrayList<Long>();

            for (SmsMessage message : messages) {
                for (SMSReceivedListner smsReceivedListner : smsListner )
                    smsReceivedListner.message(message);
            }
        }
    }
}

public static void addSMSListner(SMSReceivedListner listner){
    smsListner.add(listner);
}

public static void removeSMSListner(SMSReceivedListner listner){
    smsListner.remove(listner);

public interface SMSReceivedListner{
    public void message(SmsMessage message);
