最近用xposed进行hook回发的时候，又出现了新的问题；

android.os.NetworkOnMainThreadException；

在Android4.0以后，写在主线程（就是Activity）中的HTTP请求，运行时都会报错，这是因为Android在4.0以后为了防止应用的ANR（Aplication
Not Response）异常，Android这个设计是为了防止网络请求时间过长而导致界面假死的情况发生。

我尝试了网上的第一种解决方法：

1.在Activity的onCreate()方法中加入代码

        if (android.os.Build.VERSION.SDK_INT > 9) {StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();StrictMode.setThreadPolicy(policy);}

仍然出现了， 这种问题报错，未解决；

2. 尝试启动子线程进行网络请求

    new Thread(new Runnable(){@Overridepublic void run() {//请求详情}).start();

以下是之前的方案，直接调用 new HttpHello();
