Answer 1

According to Network security configuration

The guidance in this section applies only to apps that target Android 8.1 (API level 27) or lower. Starting with Android 9 (API level 28), cleartext support is disabled by default.

Create file res/xml/network_security_config.xml

    
        Your URL(ex: 127.0.0.1)
    

AndroidManifest.xml

    
    
        ...
    

OR you can directly set in application in manifest like this.

    
    
        ...
