错误：CLEARTEXT communication to www.baidu.com not permitted by network security policy

场景：我在使用OKHTTP3的Get异步请求http://www.baidu.com报错：

CLEARTEXT communication to www.baidu.com not permitted by network security policy

解决方案：

一：确保有网络权限

    <uses-permission android:name="android.permission.INTERNET" />

二：在application节点添加：android:usesCleartextTraffic="true"

 <application
    ……………………
     android:usesCleartextTraffic="true">

    ………………………………

  </application>
