StrictMode使用详解 - c++编程基础

同时，如果使用了penaltyDialog()方法，在应用中还会弹出提示框：

暂停监测

如果在程序运行中无法避免的会违反StrictMode中的一些定义好的策略，而我们又希望能够暂时忽略这些策略的监视，我们可以使用permitXXXXX方法来暂停这些内容的监测，在做完需要忽略的监测之后，再起用监测，代码如下所示：

StrictMode.ThreadPolicy old = StrictMode.getThreadPolicy();
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder(old)
        .permitDiskWrites()
        .build());
//doSomethingWriteToDisk();
StrictMode.setThreadPolicy(old);
