Practical way to find out if SMS has been sent

android

Solution

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   
            }
      }
  }

}

Problem

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?
