私はこの問題を多くの異なるリンクから解決しようとしましたが、私のためにはうまくいきません。画像をトリミングするためにAndroid Image Cropperライブラリを使用しています。 「画像をアップロード」ボタンをクリックするたびにトリミングが開始され、トリミングされた画像は「画像のアップロード」の画像ビューで設定され、「続行」ボタンをクリックするとログインが成功し、ログインが指示されます私はログインアクティビティを押しても、 "Upload image"アクティビティはまだそこにあり、破壊されていません。このトリミングアクティビティを使用するUpdate Activityという別のアクティビティがあり、そのアクティビティも同じように動作します。だから私は "画像をアップロードする"破壊したい。事前に感謝画像トリミングライブラリに関連するアクティビティは破棄されません
