 ### currentActivity()
 返回最近一次监测到的正在运行的Activity的名称，一般可以认为就是当前正在运行的Activity的名称。
 
+### getPackageName(appName)
+* appName \<String\> 应用名称
+
+获取应用的包名。例如getPackageName("QQ")为"com.tencent.mobileqq"。如果有相同名称的应用，只返回其中某一个的包名。如果不存在这个名称的应用，会返回空字符串。
+
+### openAppSetting(packageName)
+* packageName \<String\> 应用包名
+
+打开某个应用的应用详情页，也就是管理应用权限和可以停止其运行的页面。如果应用包名不存在，则返回false；否则返回true。

 **自动操作的函数都需要开启"自动操作服务"才能执行，否则执行到相应函数时脚本会停止运行。**
+### auto模式
+如果代码的第一行是
+```
+"auto";

+那么脚本运行前会先确保自动操作服务已开启。
 
 您也可以在设置中开启"使用Root权限自动开启自动操作服务"，从而在运行到相应语句时可以自动开启。
