Android 构建失败 - FormatException

Question

从 Unity 2018.1.something 切换到 2018.2.0.b3 后，我无法再为 Android 构建，我得到：

FormatException: 输入字符串的格式不正确

在切换到最新的 beta 版本之前，我能够毫无问题地创建构建（虽然不是使用 gradle，但使用内部构建系统）。有没有人遇到过这个问题和/或有人可以帮我解决这个问题吗？

这是我收到的全部信息：

Answer 1

这可能是因为您的“目标 API”设置为“自动（最高安装）”。如果您将 Android P 安装为您的最高 API，那么您应该将 Target API 设置更改为其他设置。我将我的设置为“Android 8.1 (Oreo)”。

Answer 2

我正在使用 Unity 版本 2019.1.9f1。收到此错误后，我一直在寻找正确的解决方案，其中一些人告诉使用正确的格式编码更改 Unity 系统文件。但是在进行系统文件编辑之前，只需重新启动我的 macOS 和 Unity3D 就可以了。

Answer 3

我通过更改设备插入的 USB 端口解决了这个问题。
