我是Android开发的新手，并尝试创建签名APK，以前工作正常但几天后我会尝试生成签名APK时显示错误消息，我一直在搜索多次并检查了很多次问题，但找不到任何解决方案，下面是我点击“生成签名APK”时收到的错误消息

不完全是解决方案。但是对于那些想要构建RELEASE APK的人来说，这是一种解决方法

我的错误原因-在构建过程中，计算机意外关机。

如果要构建发行版APK -使用gradle命令行进行构建。 （目前）有效

（Build Android Studio app via command line）

可能KeePass数据库已损坏或其他原因。 查找文件（在Windows上通常为

“ C：\ Users \ admin.AndroidStudio3.2 \ config \ c.kdbx”

（对于Windows 10的2018.1版本）; 其他-请参阅IDE用于存储设置，缓存，插件和日志的目录

删除“ c.kdbx”文件

对其进行备份（以防万一） 删除它（当然，在关闭IDE的情况下）

启动IDE并查看它是否可以解决问题。
