如何导出android Unity错误并调试日志到文件？

Question

我正在尝试为Samsung Gear VR（与Samsung Galaxy S8）开发一个应用程序，因为它要求我拔出USB电缆才能将手机插入Gear VR设备，所以我无法使用USB调试。

如何将错误和调试消息导出到我可以阅读的文件中，以找出问题所在？

到目前为止，研究表明，Android Unity Player不会保存到其他平台上的日志文件中，而adb是进行USB调试的方法……只有我不能为Gear做到这一点。

如何导出android Unity错误并调试日志到文件？

那还不存在。你必须自己做。

1。订阅Unity Log事件：

Application.logMessageReceived += LogCallback;

2。将它们存储在列表中。当应用程序即将退出时，序列化为json并保存为File.WriteAllBytes。

将其保存到的路径是Application.persistentDataPath。请参阅这篇文章，该文章显示在Unity中的任何构建中可以找到路径的位置。

以下是一个示例脚本，该脚本读取日志并在应用程序即将退出时将其保存。此外，它还可以通过电子邮件向您发送日志数据。这需要这篇文章中的DataSaver课程。请注意，该电子邮件是在下次重新打开应用程序时发送的，而不是在退出时发送的。
