Android 3.3.0 更新，错误:原因:无效类型代码:68 [英] Android 3.3.0 update, ERROR: Cause: invalid type code: 68

问题描述

在 Android Studio (3.3.0) 的新更新之后，我从 Gradle 同步收到错误消息，提示错误:原因:无效类型代码:68".即使在项目中，它也是在更新之前创建的并且根本没有改变.我试过重新安装 Android Studio，这也没有帮助，所以肯定有一些与我的项目不兼容的东西，但它没有说明是什么以及为什么.

After the new update of Android Studio (3.3.0) I'm getting error from Gradle sync saying "ERROR: Cause: invalid type code: 68". Even in project, that have been created before the update and hasn't changed at all. I've tried to reinstall Android Studio, which hasn't helped either, so there has to be something incompatible with my project, but it doesn't say what and why.

推荐答案

我遇到了同样的问题.我正在两台 PC 上开展一个项目:一台在我的办公室，一台在家里.在我的办公室，AS 3.3 更新后，一切正常，但在家里，按照我在办公室执行的相同步骤，出现错误代码 68.

I had the same problem. I was working on a project on two PCs: one at my office and one at home. In my office, after the AS 3.3 update, everything was fine but at home, after the same steps that I did at the office, the Error code 68 came out.

几个小时后，我想出了如何解决它.Android Studio 3.3 具有 "仅同步设置>实验中默认启用的活动变体"选项.禁用此功能解决了问题.但重新激活该功能会出现相同的错误，即使在成功同步 Gradle 之后也是如此.所以我认为这不是一个完整的解决方案，但至少现在我可以工作了.

After a couple of hours, I figured out how to solve it. Android Studio 3.3 has the " Only sync the active variant" option enabled by default in Settings>Experimental. Disabling this feature resolved the problem. But reactivating the feature the same error shows up, even after a successful Gradle sync. So I think this isn't a complete solution, but at least now I can work.
