android - 在 visual studio 中使用 apache cordova 构建 android 应用程序时出错？

Question

我正在尝试使用 visual studio community 2015 构建一个 android 应用程序。基本上，现在，我只是在尝试构建一个测试应用程序，以便我可以检查 IDE 是否可以完美地构建我的主要应用程序!但是当我尝试构建应用程序时，它向我显示错误。这是VS中的输出错误信息-

这是VS中输出的完整错误信息。请帮我解决这个问题并成功构建我的应用程序!

从错误消息中，您收到 Unsupported major.minor version 52.0 错误，这意味着您正在使用特定的库，它需要最低版本的 Java SE 8。

因此，要解决此问题，您需要将本地 JDK 至少更新到 1.8，并配置 Tools for Apache Cordova 才能使用它。您可以在 Tools->Options->Tools for Apache Cordova->Environment Variable Overrides->JAVA_HOME 下找到该设置。
