Question

Hi everyone I'm trying to get sent and received SMS count. I'm trying to save count in database on sending and receiving a SMS. I'm having problem in saving sent count. Plz help me solving it. Thanks in advance.

SentCount.java

public class SentCount extends Service {

public Context context;
private static int initialPos;
private static final String TAG = "SMSContentObserver";
private static final Uri uriSMS = Uri.parse("content://sms/sent");



public class content extends ContentObserver{

    public content(Handler handler, Context ctx) {
        super(handler);
        context = ctx;

        // TODO Auto-generated constructor stub
    }

    @Override
    public void onChange(boolean selfChange){
        //Context context = this.Context;

        Log.d("onchage", "on cange calld");
        DBConnect dbc = new DBConnect(context);
        int duration=Toast.LENGTH_LONG;

        ContentResolver cr = getContentResolver();
        Cursor c = cr.query(Uri.parse("content://sms"), null, null, null, null);
        if(c.moveToNext())
        {
            try{
                int leastId = getLastid();
                if(initialPos!=leastId)
                {
                    String number = c.getString(c.getColumnIndex("Address"));
                    String date = c.getString(c.getColumnIndex("Date"));
                    String msg = c.getString(c.getColumnIndex("body"));
                    initialPos = leastId;
                    dbc.SaveSentCount(number, date);
                    Log.d("Sent to:", "SMS Sent to:"+number+"  on:"+date+ "  Msg:"+msg);
                }

            }
            catch(Exception e){
                Log.v("Tag", e.getMessage());
            }
        }   
        c.close();
    }

    private int getLastid() {
        ContentResolver con = getContentResolver();
        Cursor c = con.query(uriSMS, null, null, null, null);
        c.moveToFirst();
        int lastid = c.getInt(c.getColumnIndex("_id"));
        Log.d("lastid:", "Saved"+lastid );
        c.close();
        return lastid;
    }
