1.查看当前设备栈顶Activity：adb shell dumpsys activity top

2.卸载中设备的应用：adb  uninstall 应用包名

3.启动设备的设置界面：adb shell am start com.android.settings

4.安装应用到指定设备：adb -s 设备序列号 install 应用在电脑中的路径

5.产看当前设备所以应用包名：adb shell pm list packages

6.查看当前设备屏幕dpi：adb shell wm density

7.修改当前设备屏幕dpi：adb shell wm density 160

8.查看当前设备分辨率：adb shell wm size

9.无线连接设备调试（需root权限与厂商开放端口号）：adb connect ip地址:端口号

10.查看所有已连接设备：adb devices

11.查看指定应用logcat：adb logcat V 应用包名

12.杀死当前正在运行的应用：adb shell am force-stop 应用包名

13.清除当前应用数据（相当于卸载重装）：adb shell pm clear 应用包名

25.设定视频比特率：adb shell screenrecord --bit-rate 2000000 /sdcard/test.mp4  默认比特率是4M/s，为了分享方便，我们可以调低比特率为2M

26.查看内存：adb shell df
