CORS on device (build version)

[allestaire]

Finally got a solution from this

Ionic 4 android 9 CLEARTEXT http not permitted error

ionic 4 app sends http request for android version 6,7 but gives an error saying CLEARTEXT http traffic (not permitted). I have trying to solve this by adding android:usesCleartextTraffic="true" but ionic default is true for usesCleartextTraffic. and also i tried to change url http to https. but nothing works for me. so i solved this issue temporarily by adding <domain includeSubdomains="true">localhost</domain> <domain includeSubdomains="true">YOUR-IP_ADDRESS</domain> to my network_secu…

Have to add android:usesCleartextTraffic="true" on android/app/src/main/AndroidManifest.xml

Also create android/app/src/main/res/xml/network_security_config.xml and added

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">localhost</domain>
        <domain includeSubdomains="true"><api IP Address></domain>
    </domain-config>
</network-security-config>

But dont know which one works,
