Question

我正在尝试为android构建一个Unity app，但是我收到了太多错误。以下是我的单元应用程序的错误详细信息。

这是错误1：

CommandInvokationFailure: Failed to build apk.

UnityEditor.BuildPlayerWindow:BuildPlayerAndRun()

这是错误2：

 "Build completed with a result of 'Failed'
    UnityEditor.BuildPlayerWindow:BuildPlayerAndRun()

然后我又收到了一个错误：

Build completed with a result of 'Failed'
UnityEditor.BuildPlayerWindow:BuildPlayerAndRun()

有人可以帮我解决错误。欢迎任何建议

Answer 1

由于很多事情，可能会导致此错误。

1）更新JDK

2）检查Java Path。

3）更新Android SDK

4）删除plugins文件夹下的unity资产文件夹中的重复.jar文件。

5）检查AndroidManifest.xml中的目标版本和播放器设置应该是相同的。

Answer 2

我通过将Java JDK从v10：3

降级到v8来修复它
