StrictMode使用

 StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().detectAll().penaltyLog().build();StrictMode.setThreadPolicy(policy);

StrictMode最常用来捕捉应用程序的主线程，它将报告与线程及虚拟机相关的策略违例。一旦检测到策略违例（policy violation），你将获得警告，其包含了一个栈trace显示你的应用在何处发生违例。除了主线程

病毒一般会用这段代码 关闭所有检测
StrictMode.setThreadPolicy(new StrictModeThreadPolicyBuilder().permitAll().build());
