In fact, the report IO exception means that you use the UI process to access the network and add post data, resulting in an exception. At this point you need to write the code that you access the network to a thread and there is no such problem.

Required Rights statement:

<uses-permission android:name= "Android.permission.INTERNET"/>    <uses-permission android:name= " Android.permission.WRITE_EXTERNAL_STORAGE "/>    <uses-permission android:name=" android.permission.READ_ External_storage "/>

Code to access the network:

New Thread (new  Runnable () {                        @Override            publicvoid  run () {                             access Network ~                    ///  CODING .....                     }                    }). Start ();
