2.通过调用公开或者隐藏的系统API判断并不靠谱，因为调用结果可以轻易被修改，比如直接修改Android的源代码或者借助Xposed Framework进行修改。
3.有基于模拟器特征和api返回值的检测方法都可以通过修改安卓源码的方式轻松绕过。模拟器与真机的本质区别在于运行载体。鉴于大多数的安卓模拟器基于qemu，qemu在执行程序时实际上是将其翻译成宿主机的指令，比如将安卓的arm指令翻译成PC的x86指令。为了效率上的考虑，qemu在翻译执行arm指令时并没有实时更新模拟的pc寄存器值，只会在一段代码翻译执行完之后再更新，而真机中pc寄存器是一直在更新的。基于这一点，可以设计一段CPU任务调度程序来检测模拟器 。具体的你可以参鉴DexLab上的一篇文章。当然，这个方法也是可以被绕过的，可以在理解qemu源码的基础上，修改qemu源码，但很明显这个门槛很高 。
