ActivityManager.isUserAMonkey API

【JISA20】A Large-Scale Study on the Adoption of Anti-Debugging and Anti-Tampering Protections in Android Apps 中提到：

Anti-Debugging手段中，有一种手段是Emulator Detection
Emulator Detection中，可能用到的一个api是ActivityManager.isUserAMonkey
从字面上来看，是OS提供的，用于检查当前app是否在被monkey测试的api

API 方法：

ActivityManager.isUserAMonkey()

It will tell you if the user is the Test Monkey or the monkey runner. “The Monkey is a command-line tool that that you can run on any emulator instance or on a device. It sends a pseudo-random stream of user events into the system, which acts as a stress test on the application software you are developing.”

API 用法：

public boolean wasItTheMonkey(){
    
     ActivityManager activityManager =  (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);
     if(activityManager.isUserAMonkey()) {
    
           Log.d(TAG,"it was the monkey");
           return true;
     }
     Log.d(TAG,"it was an user");
     return false;
}
