Cleartext http traffic to server.com not permitted

I'm using volley to make server calls.

Answer 1

First step is understanding why Google enforces you to use HTTPS. You can read more about it on the developers page.

As for how to fix it, there are two options:

1) Use HTTPS!

2) Create a new file in your XML folder named security_config.xml and add this:

<?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>

then in your Manifest file add this

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

    </application>
</manifest> 

For obvious reasons, the second point is not recommended!

Answer 2

Simple Solution:

Add this line in your manifest:

android:usesCleartextTraffic="true"

because I have faced the same issue with my php page for json api.

It should look like this:

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <uses-permission android:name="android.permission.INTERNET" />
    <application
        ...
        android:usesCleartextTraffic="true"
        ...>
        ...
    </application>
</manifest>

Let's hope it works.
