<p>本人在使用UiAutomator做自动化测试的时候，需要对对手机在运行用例或者执行monkey期间的cpu和内存使用情况做统计。想了一个方案，使用多线程，执行adb shell top命令，然后处理得到的信息，写入数据库中。经过尝试终于成功了，效果还不错，分享出来，供大家参考。</p>
<p>下图为数据库中的数据。</p>
<p><img src="" alt=""><br>
</p>
<p>备注：代码里包含了使用adb shell dumpsys获取信息的方法，不过在dumpsys cpuinfo的时候遇到一些问题，统计的是一个很长的时间段的，后来就放弃了这种方法，重新写了getCpuAndMemDate()方法。</p>
<p>明天来了补上注释。（已补）</p>
<p>下面是统计信息和存入数据库的类。</p>
