【解决方案1】：

每个应用都必须明确添加用户定义的证书：

res/xml/network_security_config.xml

<network-security-config>
    <base-config>
        <trust-anchors>
            <certificates src="system"/>
            <certificates src="user"/>
        </trust-anchors>
    </base-config>
</network-security-config>

还要确保 AndroidManifest.xml 在标签中包含 android:networkSecurityConfig 属性：

<?xml version="1.0" encoding="utf-8"?>
<manifest ... >
    <application android:networkSecurityConfig="@xml/network_security_config"
                    ... >
        ...
    </application>
</manifest>
