Practical way to find out if SMS has been sent

Question

I am interested in how I can figure out if SMS has been sent from the device.

In order to get notification when SMS is recieved, we use a broadcaster with:

android.provider.Telephony.SMS_RECEIVED

Important to mention that I do not send SMS from my app, I just should listen when SMS is sent from the device.

May be I should listen to some Content provider (which somehow related with SMS) and react for that change. Any ideas how I can achieve that?

Answer 1

Yes, It is possible to listen SMS ContentProvider by using ContentObserver

Here is my example for Outgoing SMS:

First register a ContetObserver with content://sms/

   public class Smssendservice extends Service{

       @Override  
       public void onCreate() {
            SmsContent content = new SmsContent(new Handler());  
            // REGISTER ContetObserver 
            this.getContentResolver().
                registerContentObserver(Uri.parse("content://sms/"), true, SMSObserver);  
       } 

       @Override
       public IBinder onBind(Intent arg0) {
            // TODO Auto-generated method stub

            return null;
       }

SMSObserver.class

       public class SMSObserver extends ContentObserver {
            private Handler m_handler = null;

            public SMSObserver(SMSLogger handler){
                 super(handler);
                 m_handler = handler;
            }

            @Override
            public void onChange(boolean selfChange) {
            super.onChange(bSelfChange);
            Uri uriSMSURI = Uri.parse("content://sms");

            Cursor cur = this.getContentResolver().query(uriSMSURI, null, null,
                 null, null);
            cur.moveToNext();

            String protocol = cur.getString(cur.getColumnIndex("protocol"));

            if(protocol == null) {
         //the message is sent out just now     
            }               
            else {
                 //the message is received just now   
            }
      }
  }

}

use the following method to send sms as well as check whether the sms get delivered or not.

send.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                String phoneNo = "Phone number to sent";
                String message = "Your message";
                if (phoneNo.length() > 0 && message.length() > 0) {
                    TelephonyManager telMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
                    int simState = telMgr.getSimState();
                    switch (simState) {
                    case TelephonyManager.SIM_STATE_ABSENT:
                        displayAlert();
                        break;
                    case TelephonyManager.SIM_STATE_NETWORK_LOCKED:
                        // do something
                        break;
                    case TelephonyManager.SIM_STATE_PIN_REQUIRED:
                        // do something
                        break;
                    case TelephonyManager.SIM_STATE_PUK_REQUIRED:
                        // do something
                        break;
                    case TelephonyManager.SIM_STATE_READY:
                        // do something
                        sendSMS(phoneNo, message); // method to send message
                        break;
                    case TelephonyManager.SIM_STATE_UNKNOWN:
                        // do something
                        break;
                    }

                } else {
                    Toast.makeText(getBaseContext(),
                            "Please enter both phone number and message.",
                            Toast.LENGTH_SHORT).show();
                }

            }

            private void displayAlert() {
                // TODO Auto-generated method stub

                new AlertDialog.Builder(YourActivity.this)
                        .setMessage("Sim card not available")
                        .setCancelable(false)
                        // .setIcon(R.drawable.alert)
                        .setPositiveButton("ok",
                                new DialogInterface.OnClickListener() {
                                    public void onClick(DialogInterface dialog,
                                            int id) {
                                        Log.d("I am inside ok", "ok");
                                        dialog.cancel();
                                    }
                                })
