An emotional Warner said he realised he may never play for his country again. But he stonewalled questions about who was aware of the ball-tampering and whether it was the first such incident within the team.
Warner, 31, told a media conference in Sydney: "I can honestly say I have only wanted to bring glory to my country through playing cricket.
"In striving to do so I have made the decision which has had the opposite effect and it's one that I will regret for as long as I live."
Coach Darren Lehmann also quit following one of the most damaging scandals to ever to hit Australian cricket.
But Warner was charged by Cricket Australia with developing the plot and telling Bancroft to carry it out.
When questioned about a possible appeal, Warner said: "That's something that I will continue to sit down with my family and weigh up all my considerations before I make any decisions."
