问题：

android stutio报错：

CLEARTEXT communication to baobab.kaiyanapp.com not permitted by network security policy

解决方案：

1. 在res目录下新建xml目录，创建network_security_config.xml文件：

2. 编写network_security_config.xml内容：

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">kaiyanapp.com</domain>
    </domain-config>
</network-security-config>

3. 在AndroidManifest.xml中添加内容：

android:networkSecurityConfig="@xml/network_security_config"
