Answer 1

As Piyush commented in my question the answer is to add android:usesCleartextTraffic="true" in manifest file with in application tag

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.mypackage">

    <uses-permission android:name="android.permission.INTERNET" />
   
    <application
        android:allowBackup="true"
        android:icon="@drawable/appicon"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        android:usesCleartextTraffic="true">
        //your android components...
</application>

Answer 2

Just add below in manifest's application tag

android:networkSecurityConfig="@xml/network_security_config"

Add below code inside the <application> where we add activities

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

Add the XML folder in the res folder. and create a network_security_config.xml file in the XML folder.

    <?xml version="1.0" encoding="utf-8"?>
    <network-security-config>
        <domain-config cleartextTrafficPermitted="true">
            <domain includeSubdomains="true">your domain which is your base url for webservice.com</domain>
        </domain-config>
    </network-security-config>
