adb shell dumpsys package [PackageName]
查看 versionCode、versionName (windows 用 findstr 过滤，linux 用 grep 过滤)
adb shell dumpsys package [PackageName] | findstr versionCode adb shell dumpsys package [PackageName] | findstr versionName
C:\Users\CJTDEV003> adb shell dumpsys package com.tencent.mm | findstr versionCode
