Android构建失败 - 格式异常

Question

在从Unity 2018.1的版本转换为2018.2.0.b3后，我无法再构建Android应用程序，出现以下错误：

FormatException：输入字符串格式不正确

在切换到最新的beta版本之前，我能够轻松创建一个构建（虽然不是使用gradle，而是使用内部构建系统）。是否有人遇到过这个问题或者可以帮助我解决这个问题？

以下是我收到的完整消息：

那听起来像是一个应该向Unity报告的错误。 - Draco18s no longer trusts SE

@AndroidTeam 什么代码？我无法提供整个项目，也不知道从这条消息的哪里开始。 - Knight Who Says Ni

Answer 1

这可能是因为您的“目标 API”设置为“自动（最高已安装）”。如果您将 Android P 安装为最高 API，则应将目标 API 设置更改为其他内容。我将我的设置为“Android 8.1（Oreo）”。

Answer 4

我正在使用Unity 2019.1.9f1版本。在遇到这个错误后，我一直在寻找正确的解决方案，有些人建议更改Unity系统文件的编码格式。但在进行系统文件编辑之前，我只是重新启动了我的macOS和Unity3D，然后问题就得到了解决。
