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

参见：https://blog.csdn.net/lazyer_dog/article/details/46050211

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
