获取当前运行的Activity

adb shell dumpsys activity | grep Run

1.4. 其它

获取手机序列号

adb get-serialno

获取CPU序列号，查看核心数量

adb shell cat /proc/cpuinfo

获取当前内存使用状态

adb shell cat /proc/meminfo

查看bug报告

adb shell bugreport

使用 ps 命令查看进程信息

adb shell ps

1.4.1. Monkey测试

adb shell monkey -v -p your.package.name 500

截屏

adb shell screencap filePath

1.4.2. Top命令查看系统进程

adb shell top

cpu瞬时数据以top命令输出为准，cpuinfo是一段时间内的平均值，而且受其他命令影响大，尤其是dumpsys meminfo。建议用busybox top -b -n 1，单次抓取，比系统带的快，计算精度高一位。

top命令显示的是任务占用1核功率相关的cpu使用情况，如果任务任务占用200%的cpu，则任务占用两个核。 top shows CPU percentage PER core, i.e if your task takes up 200% CPU then it's occupying two cores.
