这是我第一次尝试使用Android Studio并进行JUnit测试。很抱歉，如果解决方案很明显。

Answer 1

以下解决方案在Windows中为我工作：

1）在环境变量中添加一个新的“系统变量” ANDROID_SDK_HOME = D：\ Program Files \ android-sdk-windows（选择你的android sdk主目录）

2）修改系统变量Path，添加“％Android_SDK_HOME％\ tools;”

Android Studio中的JUnit测试：NoClassDefFoundError：junit / textui / ResultPrinter
