This issue was occurring in Android 9.0 for me and I fixed it by adding android:usesCleartextTraffic="true" inside application tag.

<application
    ..
    android:usesCleartextTraffic="true"

This error could be seen on Android Emulator/Device Version >= 6.0. It occurs when your app tries to send/receive request/response to a remote API that is not secure (http). That's the reason why you should stick to communicating with remote API's via a secured channel (https). But you can resolve the issue by setting the usesCleartextTraffic attribute to "true" inside the application opening tag of your android manifest file.

<application
    android:usesCleartextTraffic="true" >

The aforementioned tip solves the problem, but it tends to open a threat to data integrity. Thus you can make it better by setting up, and leveraging on a network security configuration file. This can be done thus;

Step 1: GOTO res->New->android resource directory. Create your xml resource directory

Step 2: Create a new Resource File (with the name: 'network_security_config') inside the newly created xml resource directory by navigating through (xml->New->XML Resource File).

Step 3: Paste the code below into the newly created 'network_security_config.xml' file

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">your_site_domain.com</domain>
    </domain-config>
</network-security-config>

Step 4: Goto your AndroidManifest.xml file and add the code android:networkSecurityConfig="@xml/network_security_config" inside the application opening tag of your android manifest file.

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:networkSecurityConfig="@xml/network_security_config" >

I re-created an AVD, and Run the program in the new AVD, the problem was solved. I only met it once, it worked for me, I don’t know if it will help you, if it can help you, it would be great
