                        if (cursor.moveToFirst()) {
                            System.out
                                    .println("database has data................................");
                        } else {
                            System.out
                                    .println("database has no data.............................");
                            LiveTVCategoryParser category_parser = new LiveTVCategoryParser();
                            category_parser.category_parser(Splash.this, "1",
                                    "live_root");
