I got a similar crash when I installed my app on Pie device. But it's due to the server I used HTTP instead of https. What type of domain are you using? — Brahma Datta, Mar 05 '19 at 08:06
Then check my answer. It should be Https for Pie devices. I got the crash. Include my answer in your code and it works. @NamitaAdav — Brahma Datta, Mar 05 '19 at 09:04

When an app communicates with servers using a cleartext network traffic, such as HTTP, it could raise the risk of eavesdropping and tampering of content. Third parties can inject unauthorized data or leak information about the users. That is why developers are encouraged to secure traffic only, such as HTTPS.

I Recently had the same issue for Android 9, but I had to use some URLs for different screens. So I added android:usesCleartextTraffic="true" to Manifest and it worked, but we didn't want to compromise the security of the whole app for this. So the fix was in changing links from HTTP to https.But if you had to use only http to communicate with your app then here is your solution.

Use in Manifest application tag

android:networkSecurityConfig="@xml/security_config"

And create a xml file like this.

<network-security-config>
<base-config cleartextTrafficPermitted="true"/>
<debug-overrides>
    <trust-anchors>
        <certificates src="system" />
        <certificates src="user" />
    </trust-anchors>
</debug-overrides>
