Android CTS无法写入日志

我已经针对MSM的4.2版本Aurora运行了Android 4.2 R4 CTS套件多次：完整套件（

run-CTS-plan-CTS

）或单个软件包（

run-CTS-p Android.acceleration

）。这是在Ubuntu 12.04 LTS 64位（通过VMWare Fusion v6虚拟化）上实现的

测试套件执行时通过，有时失败，但随后无法写入日志或生成报告数据：

在CTS

/repository/logs

&

/repository/results

目录中，没有新的日志或结果条目。关于

CtsXmlResultReporter

的信息少得出奇，所以我现在转向好的ol'so。有人能帮忙吗？谢谢

这只是一个chmod问题。我需要运行多个版本的CTS（4.2、4.3、4.4），并且我在root时创建了4.2目录结构
