Can't solve ERR_CLEARTEXT_NOT_PERMITTED error on android device while connecting from localhost server ionic 4

I am getting ERR_CLEARTEXT_NOT_PERMITTED error in android 9 device developed with ionic 4. I have already set usesCleartextTraffic to true in config.xml and added IP address and domain name in network_security_config.xml but still can’t solve the problem.
My Server is running at http://127.0.0.1:3000. I made sure that mobile and laptop are in the same network and added laptop’s Ip address in network_Sercurity_config.xml

My code is working fine in browser but I can’t fetch data in android device from localhost http://127.0.0.1:3000/. Can you please help in fetching data from server in mobile device

config.xml
