使用ddmlib实现android 性能监控
使用ddmlib实现android 性能监控
http://blog.csdn.net/kittyboy0001/article/details/47317855
原理：
cpu
adb shell dumpsys cpuinfo packageName
memory
adb shell dumpsys meminfo packageName
流量
cat /proc/uid_stat/uidxxx/tcp_rcv
cat /proc/uid_stat/uidxxx/tcp_snd
其中 uid的获得通过
adb shell dumpsys package packageName
取得 userId=(\d+)\s
FPS刷新频率
这个计算稍微复杂，请参见源码：
sdk/sources/android-18/com/android/uiautomator/platform/SurfaceFlingerHelper.java(以android-18中的路径为例，其他版本中也有该文件，可能路径不同)
我写了个GUI
