Internet stopped working on Android Emulator (Mac OS)

Question

I am using Android Studio 2.3(Latest). Till yesterday it was all good and working, today emulator is not connecting to the data network.
I couldn't find any solution working so far. My Mac is running on Mac OS Sierra, connected to WiFi with no proxy.

Did you tried restarting it? Also, emulator loose internet connectivity when you switch from one network to another. — Deepak Singh, Jun 14 '17 at 04:38

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

Rename the binary emulator to emulator_original
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 $@

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

I just needed one more step after this - restarting the AVD. – Dan B. May 28 '18 at 23:31

After this, close the emulator. A reboot isn't enough. – Robin Dijkhof Jan 11 '19 at 17:05
Works like a charm. Thank you u saved my night – Nicollas Feb 10 '19 at 22:45

Please note that 8.8.8.8 is Google's DNS IP, if you're concerned about your own privacy, remove this line once you're done. – Skoua Feb 14 '19 at 13:27
Thanks a lot. Perfect answer. – Deepak May 21 '19 at 19:09

I need to agree with @Skoua. Changing your DNS to Google's public DNS is a huge scratch in your privacy purse. For now this has worked, but we need a better answer to this... – Chagall Jun 11 '19 at 01:22

How is it related to emulator? – IgorGanapolsky Jun 28 '19 at 20:38

For the changes to apply you, after you click OK, you need to close System Preferences (at which point it will prompt you to save changes) – Andrew Aug 01 '19 at 14:15
In my case it worked only by adding both 8.8.8.8 and 8.8.4.4 to DNS servers – tudor Aug 28 '19 at 10:32

I don't think this is a solution; it is merely a hack. For many people it is entirely unaccaptable or even impossible to change their local DNS settings. This may work for a developer at home who doesn't care about privacy. I suggest you go with Jez's solution. – Chrissi Oct 26 '19 at 10:12
You sir, just saved my day. I was going cray-cray – sachadso Apr 28 '20 at 14:02
It's because IPV6 is broken in Android. My ISP provides IPV6 DNS, if I disable that it works. Unlike iOS which prepared for this over a decade ago, Google still hasn't fully implemented it. – Oliver Dixon Jun 07 '20 at 12:19
wipe the emulator data in android studio > change 8.8.8.8 and 8.8.4.4 to DNS servers > restart emulator, it works – Mike Victoria Aug 28 '20 at 00:59
work fine thanks. make sure to wipe data and restart emiulator – Prabudda Fernando Nov 17 '20 at 10:10
If someone from M1 Chip based laptop, then pls update your android studio, that should solve the issue apart from adding the DNS. Android Studio Arctic Fox | 2020.3.1 Patch 2 Build #AI-203.7717.56.2031.7678000, built on August 27, 2021 – Sunil Kumar Sep 16 '21 at 06:44
I just added an alias to whole command in `.zshrc` file. `alias avd="/path/to/emulator -dns-server 8.8.8.8 -avd AVDNameHere"`. So whenever I want to open emulator i just type `avd` in terminal and it just works. – Ravi Dhoriya ツ Dec 29 '21 at 19:42

For me the issue appears to stem from the DNS settings my company enforces.

In order to be able to get network access for my emulator I needed to launch the emulator with the same corporate dns-server specified.

I'm on a Mac, so first I checked my network settings to find what my DNS was set to:

System Preferences -> Network -> Wi-Fi -> Advanced -> DNS

Then navigated to the sdk emulator location (for convenience):

cd ~/Library/Android/sdk/emulator

Then listed the available emulators:

./emulator -list-avds

Then ran the desired emulator with dns server override:

./emulator @<emulator_name> -dns-server <dns.server.ip.address>

It would be nice if I could set this DNS to be used by emulators launched through Android Studio, but hopefully these steps help someone else in a similar position.

What are dns settings? – IgorGanapolsky Jun 28 '19 at 20:38
@IgorGanapolsky your DNS settings are likely to be what your company computer is using. If in doubt contact your network administrator. – Jez Jul 01 '19 at 08:09
@dbenitobaldeon 1) ensure you've downloaded an android emulator through android studio 2) ensure that the path `~/Library/Android/sdk/emulator` does indeed point to a folder containing an `emulator` script - otherwise look up the location of your android studio emulator install directory and use that instead. The path will obviously be different if you're on a windows machine. – Jez Jul 01 '19 at 08:12

In case I misunderstood your initial question @IgorGanapolsky `DNS` means "Domain Name Server", the place your computer looks to find out what IP corresponds to a website name. Eg, `google.com` might resolve to the IP address `216.58.198.174`, which is what your computer will actually use to find the website. Your DNS settings specify what server your computer will use for this service. – Jez Jul 01 '19 at 08:18

@IgorGanapolsky open `System Preferences` select `Network` then `Wi-Fi` then `Advanced` then `DNS`, and you should see a pane containing a sequence of numbers, such as `8.8.8.8`. This is a DNS address. – Jez Jul 01 '19 at 21:48

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.

quit the sim
open AVD Manager
Actions > open down arrow for more options
select Wipe Data
restart sim

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

Couldn't find any solution by tweaking network settings. So added a new virtual device from Tools -> Android ->AVD Manager by downloading a new system image(Android O, API 26). And it's working now.

If you want to use the same API level then make sure to delete the existing system image and download it again.

You can go to: System Preferences -> Network -> Wi-Fi -> Advanced -> DNS

So you add a new DNS 8.8.8.8. It might solve your problem.

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"

I wonder in what scenario this might work. Does the url `10.0.2.2` replace `localhost`? In any way, this is not an answer to connect to the internet, but only to your api. – Randy Aug 12 '20 at 08:43
