最近因为百度的后门事件，打算给应用换个推送，最后选择了极光推送，结果在接入之后出了一些比较诡异的问题，花了几天才跟踪到问题，大概就是极光推送会导致所有的Activity被重复的实例化，而我们的应用在每个Activity都会维护一个网络请求队列，总之就是几个诡异的坑碰到一起了。

简单测试了一下

• 测试代码

public class MainActivity extends AppCompatActivity {
    private static final String TAG = "MainActivity";

Clojure has support for a number of ways of passing parameters. A function body can have multiple function bodies associated with it, each with different arity. This isn't any where near as general as Haskell's pattern matching (see [1]). 


  user> (defn foo ([x] x) ([x y] (+ x y)) ([x y z] (+ x y z)))
  #'user/foo
  user> (foo 1)
  1
  user> (foo 1 2)
