[SOLVED] Xiaomi does not connect ws, other mobile phones yes

Xiaomi does not connect ws, other mobile phones yes

i have a problem in the APP im developing with my Xiaomi Mi 9 SE that don´t have with my other (older) phones like BQ M5 or some Samsung.

My APP connects to a Web Service to get some information. I have 3 enviroments for this Web Service: Test (in a PC in local LAN), preproduction and production.

Test: "http://10.60.8.223:8080/ws/webservice.wsdl"; (Xiaomi dont connect, others yes)

PRE: "https://ws-pre.myaplication.com/ws/webservice.wsdl"; (All connect correct)

PRO: "https://ws-pro.myaplication.com/ws/webservice.wsdl"; (All connect correct)

With any other mobile phones I connect to the 3 enviroments, but with the Xiaomi i cannot connect to the TEST url where I am debugging the web service.

Do you know what is happening? What can I try? Maybe Xiaomi blocks http conection but admits https?

Thank you so much in advance. Adrián.

Solution

I have solved it:

Create an xml file called network_security_config.xml in RES folder.

<?xml version="1.0" encoding="utf-8"?>
<network-security-config xmlns:android="http://schemas.android.com/apk/res/android">
    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>
</network-security-config>

in Android Manifest, inside application tag:

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