使用am start命令启动android apk应用程序

# am start -n ｛包(package)名｝/｛包名｝.{活动(activity)名称}

启动tbox service test apk
adb root
adb shell
am start -n com.demo.hmi.xxxservices.xxx/.MainActivity

程序的入口类可以从每个应用的AndroidManifest.xml的文件中得到;
启动的方法可以从每个应用的AndroidManifest.xml的文件中得到;

还可以使用 pm 和 dumpsys命令得知
这种情况下，只知道一个apk名字，也没有打开使用过，则使用

pm list package #列出全部的包名,在这些包名中找出和apk相似的包 如 com.demo.hmi.onstarservices.tbox
dumpsys package com.demo.hmi.onstarservices.tbox #列出包的信息如下
