Cleartext http traffic not permitted

To do this in Android 9 Pie you will have to set a networkSecurityConfig in your Manifest application tag like this:

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

Then create a xml file named network_security_config just like the way you have named it in the Manifest and the content of your file should be like this👇to enable all requests without encryptions:

<?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>

If this is not working, please make your request from a secure domain(HTTPS).

I also faced the same issue recently with android 9 pie.

I added in my Manifest

android:usesCleartextTraffic="true"
tools:ignore="UnusedAttribute"

second line is mentioned is to ignore the warning for SDK less than 23.

Add this into your Manifest

android:usesCleartextTraffic="true"

like this..

<application
    android:icon="@mipmap/ic_launcher"
    android:usesCleartextTraffic="true"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">
...
 </application>
