Listening for outgoing sms or send sms in Android

The following code shows how to register and event and observe changes made to the sms folder for send sms.
Most of the people states that the code may not work in future versions. Currently it works pretty with 2.1 and 2.2 and 2.3

public class SmsObserver extends ContentObserver {
	
    private Context mContext;
    
    private String contactId = "", contactName = "";
    private String smsBodyStr = "", phoneNoStr = "";
    private long smsDatTime = System.currentTimeMillis();
    static final Uri SMS_STATUS_URI = Uri.parse("content://sms");
    
	public SmsObserver(Handler handler, Context ctx) {
		super(handler);
		mContext = ctx;
	}

	public boolean deliverSelfNotifications() {
		return true;
	}

	public void onChange(boolean selfChange) {
		try{
			Log.e("Info","Notification on SMS observer");
			Cursor sms_sent_cursor = mContext.getContentResolver().query(SMS_STATUS_URI, null, null, null, null);
			if (sms_sent_cursor != null) {
				if (sms_sent_cursor.moveToFirst()) {
					String protocol = sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("protocol"));
					Log.e("Info","protocol : " + protocol);
					//for send  protocol is null
					if(protocol == null){
						/*
						String[] colNames = sms_sent_cursor.getColumnNames();		        		
						if(colNames != null){
							for(int k=0; k<colNames.length; k++){
								Log.e("Info","colNames["+k+"] : " + colNames[k]);
							}
						}
						*/
						int type = sms_sent_cursor.getInt(sms_sent_cursor.getColumnIndex("type"));
						Log.e("Info","SMS Type : " + type);
						// for actual state type=2
						if(type == 2){
							Log.e("Info","Id : " + sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("_id")));
							Log.e("Info","Thread Id : " + sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("thread_id")));
							Log.e("Info","Address : " + sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("address")));
							Log.e("Info","Person : " + sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("person")));
							Log.e("Info","Date : " + sms_sent_cursor.getLong(sms_sent_cursor.getColumnIndex("date")));
							Log.e("Info","Read : " + sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("read")));
							Log.e("Info","Status : " + sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("status")));
							Log.e("Info","Type : " + sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("type")));
							Log.e("Info","Rep Path Present : " + sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("reply_path_present")));
							Log.e("Info","Subject : " + sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("subject")));
							Log.e("Info","Body : " + sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("body")));
							Log.e("Info","Err Code : " + sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("error_code")));
							
							smsBodyStr = sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("body")).trim();
							phoneNoStr = sms_sent_cursor.getString(sms_sent_cursor.getColumnIndex("address")).trim();
							smsDatTime = sms_sent_cursor.getLong(sms_sent_cursor.getColumnIndex("date"));
							
							Log.e("Info","SMS Content : "+smsBodyStr);
							Log.e("Info","SMS Phone No : "+phoneNoStr);
							Log.e("Info","SMS Time : "+smsDatTime);
						}
					}
				}
			}
			else
				Log.e("Info","Send Cursor is Empty");
		}
		catch(Exception sggh){
			Log.e("Error", "Error on onChange : "+sggh.toString());
		}
		super.onChange(selfChange);
	}//fn onChange
	
}//End of class SmsObserver

To register the content observer the following code lines are essential

static final Uri SMS_STATUS_URI = Uri.parse("content://sms");
SmsObserver smsSentObserver = new SmsObserver(new Handler(), this);
this.getContentResolver().registerContentObserver(SMS_STATUS_URI, true, smsSentObserver);
