安卓9.0联网问题

安卓9.0默认不允许http请求

我们可以在APPlocation里面加上 android:usesCleartextTraffic="true"

但是我的是https的连接，所以应该不是这个问题，后面我看了一下错误结果如下
java.net.SocketException: socket failed: EPERM

emm最后找了半天发现卸载软件后重新安装就没问题了。。。。。

这模拟器是真的坑！

have a same problem, with volley, but this is my solution:

In Android Manifiest, in tag application add:

android:usesCleartextTraffic="true"
android:networkSecurityConfig="@xml/network_security_config"

create in folder xml this file network_security_config.xml and write this:

<?xml version="1.0" encoding="utf-8"?>
  <network-security-config>
    <base-config cleartextTrafficPermitted="true" />
  </network-security-config>

inside tag application add this tag:

<uses-library android:name="org.apache.http.legacy" android:required="false"/>
