Answer 1

Starting with Android 9 (API level 28), Android doesn't allow plaintext traffic (HTTP) by default, requiring apps to use HTTPS to enhance security during data transfer.

So for test environment, we can allow http traffic by setting android:usesCleartextTraffic="true" in your AndroidManifest.xml.

Sample:

<application
    ...
    android:usesCleartextTraffic="true"
    ...>
    ...
 </application>
