+使用插件有两个目的：1是实现网络请求的自动监控和模拟弱网功能，不需要手动写其他代码。2是可以实现三方jar包内的请求的hook。
 但使用插件会稍微影响到编译速度。如果不需要这个功能，可以通过手动添加DoraemonInterceptor的方式进行OkHttp的监控,如下：
 
 ```
 OkHttpClient client = new OkHttpClient().newBuilder()
+                //用于模拟弱网的拦截器
+                .addNetworkInterceptor(new DoraemonWeakNetworkInterceptor())
+                //网络请求监控的拦截器
                 .addInterceptor(new DoraemonInterceptor()).build();
 ```
