Android – Listen for incoming SMS messages

Get the latest m3-rc37a version of android

Here’s a screen shot

Setup the Android Manifest with the permission and the Intent Receiver

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="org.apache.sms">
    <uses-permission id="android.permission.RECEIVE_SMS" />
    <application>
        <receiver class="SMSApp">
            <intent-filter>
                <action android:value="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>
    </application>
</manifest> 

Code a simple Intent Listener

package org.apache.sms;

import android.app.NotificationManager;
import android.content.Context;
import android.content.Intent;
import android.content.IntentReceiver;
import android.os.Bundle;
import android.provider.Telephony;
import android.util.Log;
import android.telephony.gsm.SmsMessage;

public class SMSApp extends IntentReceiver {
    private static final String LOG_TAG = "SMSApp";

    /* package */ static final String ACTION =
            "android.provider.Telephony.SMS_RECEIVED";

    public void onReceiveIntent(Context context, Intent intent) {
        if (intent.getAction().equals(ACTION)) {
            StringBuilder buf = new StringBuilder();
            Bundle bundle = intent.getExtras();
            if (bundle != null) {
                SmsMessage[] messages = Telephony.Sms.Intents.getMessagesFromIntent(intent);
                for (int i = 0; i &lt; messages.length; i++) {
                    SmsMessage message = messages[i];
                    buf.append("Received SMS from  ");
                    buf.append(message.getDisplayOriginatingAddress());
                    buf.append(" - ");
                    buf.append(message.getDisplayMessageBody());
                }
            }
            Log.i(LOG_TAG, "[SMSApp] onReceiveIntent: " + buf);
            NotificationManager nm = (NotificationManager) context.getSystemService(
                    Context.NOTIFICATION_SERVICE);

            nm.notifyWithText(123, buf.toString(),
                    NotificationManager.LENGTH_LONG, null);

        }
    }

    private void appendData(StringBuilder buf, String key, String value) {
        buf.append(", ");
        buf.append(key);
        buf.append('=');
        buf.append(value);
    }
}

Running the sample



  • Install the APK using “adb install SMSApp.apk” as usual

  • Open a telnet session to localhost at port 5554 and type “sms send +5085551212 hello” to simulate an sms message
  • Download Source and APK from here – SMSApp.zip

  6. Hi,
    This is cool. But I thought that the emulator should be listening to any incoming SMSs by default. Its fucntionality that should be provided in the phone.

    Anyway, this is a good example.

  7. Hi this is bhavan am just tried to use your SMSApp application but i got this error at line

    NotificationManager.LENGTH_LONG, null);
    NotificationManager.LENGTH_LONG cannot be resolved
    could you please suggest how to solve this error to my mail id.And is this application work to send an sms from emulator?

    Comment by Bhavana — March 20, 2008 @ 4:02 am

  8. i’ve the same error :|

    NotificationManager.LENGTH_LONG cannot be resolved

    Comment by shitfull — March 28, 2008 @ 1:01 pm

  9. You can use Toast.maketext() replace Notification manager

    Comment by RoSippA — May 6, 2008 @ 3:03 am

  10. Hello,
    Use

    import android.widget.Toast; // import

    Toast.makeText(context, sb.toString(), Toast.LENGTH_LONG).show();
    instead of NotificationManager.

    Comment by Rifat Shahriyar — May 9, 2008 @ 4:55 am

    • Hi My Dear,
      Here I have imported this package but I have a doubt about the first argument(context) of makeText method. Here which type of value we can pass?
      Thanks in advance………

      • do you really think he is going to call India to tell you which type of value you can pass?

        Comment by Ejder Yurdakul — March 7, 2010 @ 1:26 pm

  11. sorry buf.toString() instead of sb.toString()

    Comment by Rifat Shahriyar — May 9, 2008 @ 4:57 am

  12. .i’m using m5-rc15 and have used android.widget.Toast as Rafit says w/o error. But I’m having a problem deploying: when i try “adb install “, 0 bytes install – “110 KB/s (0 bytes in 3520.000s)”. In Eclipse, I’m not sure how to setup the prj so that it builds and runs in the emulator (theres no activity in this prj)..
    Thoughts?

    Comment by Yasmin — October 17, 2008 @ 2:24 am

  16. the class IntentReceiver does no longer exists in the SDK 1.1 and is renamed to BroadcastReceiver.

    hope this helps running this nice example.

  18. DoM:

    It appears this package is only available in the Open Source version and not available in 1.1 SDK.

    Comment by MV — March 18, 2009 @ 10:34 pm

    Comment by shubham — February 27, 2010 @ 12:07 am

  22. Hi,
    Can my application receive SMS when its not running?

    My requirement is:
    1.My application is in dead state.
    2.My device receives a SMS.
    3.My application while in dead state, receives it. If its in some particular format eg with some prefix eg: ‘MyAppName':xyz, my application will read the SMS and will call API to start itself do processing as per commands in SMS text.
    4. Basically I am trying to do application wake up by any means.
    THanks
    Sam

    Comment by sam — March 18, 2010 @ 12:58 am

    • I have similar need, Sam. My application may be triggered to run by an SMS message with contents of a particular format; or when the app is already running an incoming SMS may trigger an action within the app.

      It seems to me that there may need to be a service always running, without a UI, to always receive the SMS arrival intents, and that that in turn would start the activity in the application which initializes the UI, or begins the app’s response within an existing UI.

      However, my app is only interested in those SMSs that are directed to the app; all others should be handled by the default SMS app; and any SMSs that my app handles should be invisible to the user, i.e. should not appear in the SMS inbox — whether the app causes them to be deleted from the inbox or can intercept them before they reach the inbox.

      I’ve seen examples of how to set yourself up to receive incoming SMS notifications, but nothing that gives a hint as to how to accomplish the rest. Worse, I recall having read something somewhere that said that there is no SMS content provider exposed. Which could mean that what I want to do is impossible. Which would be a nice thing to find out sooner than later…

      Comment by Paul — March 24, 2010 @ 12:43 pm

      • Hi Paul,
        Did this App Directed SMS problem resolved? I tried deleting the SMS from Inbox but I get exceptions.

        thanks
        Sam

        Comment by sam — April 26, 2010 @ 8:31 am

      • hi Sam n Paul
        I’m also searching for the same thing for past 2 days. I’d got how to send and receive sms and to invoke an activity upon receiving an sms, but is invoked for any sms and that’s not my need..
        If u’d got any thread on this please share it, i may be grateful to you.
        regards…

    • Not yet. I haven’t followed up on it. This task has been assigned to another member of our team. She believes it can be done but as far as I know hasn’t actually tried yet.
