通过命令启动一个activity(am pm 命令)

一、am的含义是activityManager
主要作用是启动activity、service 、broadcast 
 
1.通过adb命令启动acitvity,首先需要设置activity 的 exported 属性为true,不写默认为false
如果不设置为true 则执行命令是报错:java.lang.SecurityException: Permission Denial: starting Intent
2.在命令行输入 adb shell am start -n 包名/全路径 (-n可以省略)
或者 adb shell am start -a action名称  来启动activity
 
start 时的命令包括
