Android : Parse Query no working in android

I am using parse sdk to store data. I am using below code to fetch data from parse.

I only want those data which are updated after last sync datetime.

ParseQuery<ParseObject> parseQuery = ParseQuery.getQuery(P_TableName);
// fetch only those data which updated after last updated sync date.
parseQuery.whereGreaterThanOrEqualTo("updatedAt", date);
List<ParseObject> lstObj = parseQuery.find();

Note: date is Object of Date.

But still it is providing me all data. It was working before few days. Now It's not working in android.
