Question

I parsed the json data and put these values in database(Sqlite database). Next time when i open the activity it again parsed the data and put these values in database.
so i want to check first whether data is in sqlite?, if so then i need to skip parsing. And just get these values from database. how can i do this?

Try this.

public int isDataAvailable()
    {
        int total = 0;
        try
        {
            Cursor c = null;
            c = db.rawQuery("select id from mycoupon", null);

            if(c.getCount() != 0)
                total = c.getCount();

            c.close();
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
        return total; 
    }

If there are no records in table then it returns 0 otherwise returns no of records.
