Java Android应用程序发布时崩溃
因此，我必须开发一个应用程序来玩游戏垃圾，我必须修改它以允许主屏幕上有规则、买入系统和投注系统。在这次修改之前，应用程序工作时没有任何问题，但是在添加修改后，应用程序在我启动它的那一刻就崩溃了。在这一点上，我找不到任何修复它的方法，其他线程上列出的答案似乎不适用，所以我转向so寻求帮助。以下是我的全部代码： `Java Android应用程序发布时崩溃,java,android,Java,Android,因此，我必须开发一个应用程序来玩游戏垃圾，我必须修改它以允许主屏幕上有规则、买入系统和投注系统。在这次修改之前，应用程序工作时没有任何问题，但是在添加修改后，应用程序在我启动它的那一刻就崩溃了。在这一点上，我找不到任何修复它的方法，其他线程上列出的答案似乎不适用，所以我转向so寻求帮助。以下是我的全部代码： ` 废话！ 试试你的运气！ 2. 你的胜利：0 豪斯赢：0 滚！ 你赢了！ 要点： 祝你下次好运！ 最低买入价为5.00美元，无任何变化！ 最高买入价为$200.00，无变化！ 最
