Android SMS Receiver / Handler

Question

I just want to ask if anyone knows or have a working SMS receiver / handler code for android. Because I've been searching the net for days now and I still haven't seen an updated code, most seem to have deprecated codes on them like the one here http://mobiforge.com/developing/story/sms-messaging-android I would REALLY appreciate it if someone could teach me the new codes for receiving SMS in an application. thanks!

Answer 1

This Should work, and is not deprecated, if you replace android.telephony.gsm.SmsMessage with android.telephony.SmsMessage. it's just about listening for android.provider.Telephony.SMS_RECEIVE.

Answer 2

There is a thread here which includes code to do what you're asking for. Note that there are some corrections in the answers there.

Answer 3

I've just recently implemented a working BroadcastReceiver to handle SMS messages. The key parts are the manifest and the BroadcastReceiver.

In the manifest you need the RECEIVE_SMS permission:

<uses-permission android:name="android.permission.RECEIVE_SMS" />

You don't need READ_SMS. Your receiver entry should look something like this:

<receiver
    android:name=".IncomingSmsBroadcastReceiver"
    android:enabled="true"
    android:exported="true">
    <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

The bit that most people seem to forget is android:exported="true" which is required because the broadcast originates from outside your application. Some postings suggest you need android:permission="android.permission.RECEIVE_SMS" or android:permission="android.permission.BROADCAST_SMS" but this isn't the case.

My BroadcastReceiver implementation looks like this:

package smsmanager;

import java.util.List;

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

public class IncomingSmsBroadcastReceiver extends BroadcastReceiver {

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

    @Override
    public void onReceive(final Context context, final Intent intent) {

        if (intent != null && SMS_RECEIVED.equals(intent.getAction())) {
            final SmsMessage smsMessage = extractSmsMessage(intent);
            processMessage(context, smsMessage);
        }

    }

    private SmsMessage extractSmsMessage(final Intent intent) {

        final Bundle pudsBundle = intent.getExtras();
        final Object[] pdus = (Object[]) pudsBundle.get("pdus");
        final SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdus[0]);

        return smsMessage;

    }

    private void processMessage(final Context context, final SmsMessage smsMessage) {
        // Do something interesting here
    }

}

And everything works just as I want it to, and I can stop burning up my SMS allowance testing ths
