Christie sent the home crowd into raptures as he upset Taiwan's sixth-ranked Chou Tien-chen 21-18, 20-22, 21-15 to become Indonesia's first men's singles champion since 2006, before ripping off his shirt in celebration.
The 20-year-old's surprise win capped a memorable run for Indonesia's men after Anthony Sinisuka Ginting knocked out world champion Kento Momota and Olympic gold-medallist Chen Long en route to bronze.
"I did not expect that I can win a gold at the Asian Games. Actually there are a lot of good players here and I never expected that I could come out as a winner," said Christie.
Kevin Sanjaya Sukamuljo and Marcus Fernaldi Gideon, nicknamed the "Minions" owing to their stature, rounded off the party as they won an all-Indonesian final against Fajar Alfian and Muhammad Rian Ardianto 13-21, 21-18, 24-22.
In a celebratory atmosphere at the badminton stadium, Sukamuljo and Gideon collapsed to the floor as their opponents' final shot went wide to settle a tense final game.
Once-dominant China failed to win a singles badminton medal for the first time in 38 years, but otherwise it was another productive day for the Olympic heavyweights.
China passed 200 medals early in the day and they finished with four golds in track and field, including Xie Wenjun's come-from-behind victory in the 110m hurdles.
Xie, 28, capitalised on a late stumble by Taiwan's Chen Kuei-ru to claim China's ninth straight win in the event, before revealing he had received "special instructions" from Chinese hurdling great Liu Xiang.
"Before the match, before I went to Europe, he gave me special instructions. I really thank him," said Xie, who also won the sprint hurdles in 2014.
But it was Bahrain who took the honours in the Games' inaugural mixed relay, a new venture which will feature at the Tokyo 2020 Olympics. India were second, nearly four seconds behind.
"It's the first time I've raced with girls!" said Bahrain's Abbas Abbas.
As the dust settled on day 10, China were on 97 gold medals, more than double Japan's 43, with South Korea on 32 and Indonesia on 24.
