java-无法编译为android(Unity)

我正在尝试将我的VR项目编译为Android手机.

但是我一直收到以下错误：

Failed to compile resources with the following parameters:
-bootclasspath "C:/Program Files (x86)/Android/android-sdk\platforms\android-26\android.jar" -d "C:\Users\**\Documents\**\**\Temp\StagingArea\bin\classes" -source 1.6 -target 1.6 -encoding UTF-8 "com\google\gvr\keyboardsupport\R.java" "com\google\gvr\permissionsupport\R.java" "com\google\vr\cardboard\R.java" "com\google\vr\keyboard\R.java" "com\***\**\R.java" "com\unity3d\unitygvr\R.java"
warning: [options] source value 1.6 is obsolete and will be removed in a future release
warning: [options] target value 1.6 is obsolete and will be removed in a future release
warning: [options] To suppress warnings about obsolete options, use -Xlint:-options.

我已经安装了Android Studio& Android SDK我也安装了最新版本的Java SDK

谁能告诉我我能做什么？

解决方法:

我认为这是由JDK 9引起的.我在装有JDK 9的家用计算机上看到相同的错误,在使用JDK 8的工作中看不到该错误.(具体来说,我有使用JDK 8 Update 131(64位)进行此操作.)

如果我正确阅读了错误消息,则看起来好像是unity或android工具链中的某件事正在请求针对Java 6.0(1.6)编译源文件.那已经有11年的历史了,因此在JDK 9中被标记为不推荐使用.降级到JDK 8应该可以解决它.最终,该工具链将需要更新以支持较新的版本.
