Sorun benim manifiest.xml dosyasıdır Etkinliğimin bir geri düğmesine bastığımda, bunun yerine bir uygulamayı doğrudan sonlandırmaya gider homeFragment'a gider.

Lütfen bu sorunu çözmek için bana yardımcı olun.

Answer 1

Etkinliğinizi ön tarafa getirmek için niyeti taşıyan etiketleri kullanıyorsunuz, parentIntent.setFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT | Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); Bu, uygulamanızın neden kapanmasının nedeni olabilir, çünkü şimdi etkinliğiniz en ön sırada yer alıyor ve artık daha fazla etkinlik yığını yok ayrıldı.
