 Android 9.0及以上的机器，报如上错误。

解决：res的xml文件夹下定义一个network_security_config.xml文件，内容如下

<network-security-config>

     <domain-config cleartextTrafficPermitted="true">

          <domain includeSubdomains="true">127.0.0.1</domain>

     </domain-config>

     <base-config cleartextTrafficPermitted="true">

          <trust-anchors>

              <certificates src="system" /> </trust-anchors>

      </base-config>

</network-security-config >

在AndroidManifest.xml的<application>中加入该配置

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

 

亲测可行。
