1 cleartext http traffic not permitted

okhttp

2 java.net.UnknownServiceException: CLEARTEXT communication ** not permitted by network security policy

原因：權(quán)限

解決方法

在 res 下新增一個 xml 目錄，然后創(chuàng)建一個名為：network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>

<network-security-config>

 <base-config cleartextTrafficPermitted="true" />

</network-security-config>

AndroidManifest文件下application下增加配置

<application 
      ...
      android:networkSecurityConfig="@xml/network_security_config" 
      ...
>
