Android SDK的说明很有误导性。
android的service，只是用于后台，一般不能用于运算量很大或者占用线程时间很长的处理。
service和activity一样，都是在主线程中调用的，他们的那些方法，都是被主线程的looper和handler根据事件和状态分散处理的，如果一个函数时间很长，都要出现ANR问题。
如果一个函数执行时间很长，需要起线程，或者起service，但这个service需要单独的进程中运行，不能和activity在一个进程中。
在一个进程中，占时间长的函数，最好能用异步线程(这要求运算模块很独立才行),用普通线程，同步不好也会有问题，同步问题最好是状态机+handler来处理吧。
