If you have Blue Coat Unified Agent, internet wont work. Kindly uninstall it.

It can be uninstalled by going to below folder- /Library/Application Support/bcua

Answer 2

It's a bug with IPv6 name resolution, removing any IPv6 nameserver in /etc/resolv.confg fixes the issue, see https://issuetracker.google.com/issues/155686508#comment3

Answer 3

I'm new to Android Studio and just ran into this issue. Network in the sim was working fine and stopped working for some reason. Didn't like any of the solutions above, so I poked around the AVD Manager and found an option to wipe the data on the sim.

1. quit the sim
2. open AVD Manager
3. Actions > open down arrow for more options
4. select Wipe Data
5. restart sim

Answer 4

Go to open AVD manager and click wipe data

That's it now the Internet will work. This is how I solved my Issue.

Answer 5

if its an android project, u can change the baseUrl to 10.0.2.2, note this is only applicable from android emulator, will not work on phone

e.g Api endpoint will now look like this: val baseUri : String = "http://10.0.2.2/restapi/"

val loginEndpoint = "${baseUri}login"

Answer 6

In Mac OS go to: System Preferences -> Network -> select Wi-Fi os left panel -> Advanced on right panel -> DNS -> add new DNS server; for example 8.8.8.8 and 8.8.4.4 (Google Public DNS) or 1.1.1.1 and 1.0.0.1 (Cloudflare and APNIC DNS) or another public DNS provider. Then restart the emulator so the changes take effect.

Another option is to pass dns-server params when start Android emulator. According with this solution https://stackoverflow.com/a/51858653/3328566, I changed the emulator executable name and I created a bash script to load the AVD with param -dns-server 8.8.8.8.

In your Android SDK default folder /Users/[MY_USER_ACCOUNT]/Library/Android/sdk/emulator/emulator

1. Rename the binary emulator to emulator_original
2. Create a bash script named emulator that contains:

#!/bin/bash /Users/[MY_USER_ACCOUNT]/Library/Android/sdk/emulator/emulator_original -dns-server 8.8.8.8 $@

3. Change the script permissions with chmod +x emulator

Now, you can start AVD from Android Studio normally

In this case, you don't need to set DNS server in System Preferences. You are setting the DNS server only for the emulator, avoiding other problems
