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

If <path> is a file, the bug report will be saved as that file.
If <path> is a directory, the bug report will be saved in that directory with the name provided by the device.
If <path> is omitted, the bug report will be saved in the current directory with the name provided by the device.
