public boolean isFieldExist(String tableName, String fieldName)

     boolean isExist = false;
     SQLiteDatabase db = this.getWritableDatabase();
     Cursor res = db.rawQuery("PRAGMA table_info("+tableName+")",null);
    res.moveToFirst();
    do {
        String currentColumn = res.getString(1);
        if (currentColumn.equals(fieldName)) {
            isExist = true;
        }
    } while (res.moveToNext());
     return isExist;
