react native android9 axios network error

react native 發布成apk后網絡請求會報 network error 是因為android9以后http協議不能用，要用htts協議。需要改成配置能兼容http協議，修改信息如下：

 android:networkSecurityConfig="@xml/network_security_config"

 

android\app\src\main\res 目錄新增兩個文件 network_security_config.xml  和  update_file_provider.xml  配置信息如下

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>
</network-security-config>
