问题描述

There are many similar questions with regards to setting the language level for Java when performing an Android build. 关于在执行Android构建时为Java设置语言级别，存在许多类似的问题。 But all of these answers show you how to set the language level in Eclipse or NetBeans or Android Studio . 但是所有这些答案都向您展示了如何在Eclipse或NetBeans或Android Studio中设置语言级别。 I am using Nsight Tegra-Android in Visual Studio 2012 building using Ant and I don't see anywhere in Project->Properties that I can change the language level. 我在使用Ant的 Visual Studio 2012中使用Nsight Tegra-Android，并且在Project-> Properties中看不到可以更改语言级别的任何地方。

I have CodeWorks for Android 1R4 installed which is the latest and the paths I have set up are to the following packages: 我已经安装了适用于Android 1R4的CodeWorks，它是最新的，并且我设置的路径是以下软件包：

NDK R10e NDK R10e
JDK 1.7.0_71 JDK 1.7.0_71
Ant 1.8.2 蚂蚁1.8.2

which are specified under Tegra->Options in Visual Studio. 在Visual Studio中的Tegra-> Options下指定。 Where is Ant getting -source 1.5 from? Ant从哪里获得-source 1.5？
