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

Question

我试图用visual studio community 2015构建一个android应用程序。基本上现在，我只是试图构建一个测试应用程序，这样我就可以检查IDE是否适合构建我的主要应用程序！但当我试图构建应用程序时，它显示了错误。下面是VS中的输出错误消息-

这是VS中的完整错误消息输出。请帮助我解决这个问题，并建立我的应用程序成功！

Answer 1

从错误消息中，您得到的是unsupported Major.minor Version52.0错误，这意味着您使用的是某个库，该库需要Java SE8的min版本。

因此，要解决这个问题，您需要将本地JDK更新到至少1.8，并为Apache Cordova配置使用它的工具。您可以在tools->options->tools for Apache Cordova->Environment Variable overrides->java_home下找到该设置。
