如何使用Cafe??

1、我按照Readme中的步骤进行，在执行make.sh时抛出如下异常：
cat: /proc/cpuinfo: No such file or directory
./make.sh: line 26: build/envsetup.sh: No such file or directory
./make.sh: line 58: mm: command not found
./make.sh: line 60: mm: command not found
但通过adb shell是可以访问到这个文件的，请教是什么原因？

2、cafe具体有哪些功能？使用了robotium编写测试用例，自定义的testRunner，可以监控CPU，帧数等性能吗？

Start with the README and make.sh, then inspect the referenced build/envsetup.sh path and the adb shell context described in the report. Compare the documented setup with the reported errors and identify which Cafe features and performance-monitoring capabilities are actually documented; done means providing clear usage and capability guidance.
