Android 模拟器无法访问 inte.net

Question

I know that similar questions have been asked before, but my problem is new only after installing Android Studio 2.3, the latest version in March 2017. I have several years experience developing Android applications, and I have never encountered this problem before. After upgrading to version 2.3 of Android Studio, my emulator is no longer able to access the inte.net. I even uninstalled/reinstalled Android Studio 2.3 from scratch and created a new emulator, and I am still getting the same error. This is not an app problem. I can't even access the inte.net from Chrome, and I wasn't having this problem last week. The message that I get says that the server DNS address could not be found -- DNS_PROBE_FINISHED_BAD_CONFIG. The only thing that has changed on my computer in the last week is the new version of Android plus possibly updates to Windows 10. And yes, my computer has access to the inte.net. Below is an image of my emulator when I try to use Chrome to search for "Google".

Answer 1

👉 1st try "Cold booting" the emulator as suggested here .

👉 If cold booting doesn't work, try changing the DNS address of your network to 8.8.8.8 (Google's DNS) or another of your preference:

MacOSX:

• Open "System Preferences"
• Click on "Network"
• Select the network which your computer is connected and click on "Advanced"
• Select "DNS", Select the "+" button, type "8.8.8.8" (Google's DNS) or if you prefer OpenDNS, "208.67.222.222"
• Select "Ok" and "Apply"

Windows & Linux:

https://developers.google.com/speed/public-dns/docs/using

After that close the emulator and start it again.

Answer 2

After trying many of these solutions, I was going to just delete my current AVD and make it again, but when I clicked the down arrow on the AVD, I noticed "Cold Boot Now".

On a whim I tried that. Lo and behold my emulator has internet connectivity again!

Command-line approach

In case you start Emulator through command, pass -no-snapshot-load option, like:

%ANDROID_HOME%/emulator/emulator.exe -netdelay none -netspeed full -no-snapshot-load -avd Pixel_2_API_28

Or for MacOSX:

$ANDROID_HOME/emulator/emulator -netdelay none -netspeed full -no-snapshot-load -avd Pixel_2_API_28

Note that you may need to change -avd Pixel_2_API_28 part (with your own Virtual-Device name).

Also, most tools use ANDROID_HOME environment-variable name, hence define that (if not already), but nowadays ANDROID_ROOT is yet another naming-option.

Decision ^(edit)

Ok, for those saying why not just wipe data and restart. Do you reformat your PC every time you restart it? Wiping data on the emulator is just like doing a factory reset to a phone or reformatting your hard drive on your PC and reinstalling your OS. It is unnecessary unless the data is totally corrupt.

When you shut off the emulator and restart it, it is like putting your PC in hibernate or sleep mode. Memory is not wiped, it is saved.

Doing a cold boot is the same as rebooting your phone or rebooting your PC. It resets memory and lets things reload. This allows the network emulation to start with clean memory and connect properly.

So, don't wipe your data. Just cold boot. If it still doesn't work, then wipe, but save that as a last resort.

Answer 3

I found a temporary solution on an old Stack Overflow thread at Upgraded to SDK 2.3 - now no emulators have connectivity . Note that this thread talks about Android SDK 2.3, not Android Studio 2.3. The problem seems to be that the emulator can't find the DNS my computer is currently using, and the temporary workaround is to start the emulator from the command line and specify the DNS server. Whatever problem occurred back then must have reappeared in the latest version of Android Studio.

The temporary solution outlined below fixes the problem with the emulator accessing the internet. However, it does not fix the problem that occurs when trying to run Android Device Monitor. Doing so will still make the emulator go offline as described above.

Note that there are two files named "emulator.exe" in the sdk -- one under sdk\tools and another under sdk\emulator. Either might work below, but I use the one under sdk\emulator.

The first step is to find where the SDK is located. Assuming a user name of "jdoe" and a default installation of Android Studio on Windows, the SDK is most likely in

C:\Users\jdoe\AppData\Local\Android\sdk

The second step is to determine the name of the AVD (emulator) that you want to run. The command

C:\Users\jdoe\AppData\Local\Android\sdk\emulator\emulator.exe -list-avds

will show the names of your AVDs. On my computer, it shows only one, Nexus_5X_API_25.

To start the emulator from the command line with a specified DNS server, use something like the following:

C:\Users\jdoe\AppData\Local\Android\sdk\emulator\emulator.exe -avd Nexus_5X_API_25 -dns-server 8.8.8.8

In this case, 8.8.8.8 is a Google public domain name server.

The above commands can be shortened if you create appropriate environment variables and edit your PATH environment variable, but I recommend caution when doing so.

Answer 4

[UPDATE 2022] for Mac Users

For NOT Apple Silicon users

1. System Preferences
2. Network
3. WiFi > Select Advanced
4. From Advanced Choose DNS tab
5. Add DNS Server 8.8.8.8
6. Emulator must be restarted after DNS Server has been added (Thanks to @kapusch)

For Apple Silicon users

as per @bourdier-jonathan You can fix the Silicon issue here: Emulator appearing offline on M1 Mac after the last update of arm64-v8a

By replacing the AVD system images you have downloaded with the r02 images. Because It appears r03, r04, and r05 all don't work on m1

Answer 5

Updating my WIFI adapter to resolve DNS on 8.8.8.8 solved the issue for me. It started to happen after an Apple update which messed up the DNS address.

Answer 6

只需打开AVD 管理器并擦除该模拟器的数据即可。

Answer 7

Open Android emulator and go to the Extended Controls . Then go to the setting => proxy(Tab), uncheck "Use Android studio HTTP proxy setting" and click "Apply".

Answer 8

macOS: long Story short.. make sure your DNS settings 8.8.8.8 is the first in line, wipe your data and do a cold boot.

Answer 9

I experienced this same issue after upgrade. Upon opening the Chrome browser in the emulator, google.com could no longer be reached.

I found a post on SO that suggested the problem was with the emulator trying to use a disconnected network adapter. For me the problem was occurring when I was connected to a LAN. Disabling the wireless LAN adapter fixed the issue.

To disable the adapter:

1. Navigate to Network connections
2. Find the adapter
3. Right click and choose disable

Answer 10

我已经解决了从 AVD Manager 中擦除数据的问题

Answer 11

提醒：如果您在计算机上打开VPN系统，Android Emulator 互联网连接将无法正常工作。

Answer 12

This happend to me when the emulator froze and I had to kill the process. The signal icon always showed the small "x" as in the screenshot and no internet connection was successful.

The only thing that helped was uninstalling and reinstalling the emulator (not the AVD images)

In Android Studio:

Tools-> Android -> SDK Manager Uncheck "Android Emulator" and let it uninstall then check again and let it install again.

Answer 13

I am also facing the same problem, but I am trying to solve the problem using various posts. Today I discovered this problem. Your computer configuration is most likely the problemm, not Android Studio and the Android Emulator.

The problem is coming from your Network setup. Just set the Primary DNS Server to 8.8.8.8, which will solve the problem.

Answer 14

I got a simple and permanent solution for this issue in windows.

Go to network and internet option->

click on Etherenet or wifi (for which you are connected) option ->

Click on change adapter option ->

Right click on the network for which you have connected.

A dialog box will be opened and just click on Internet protocal version (TCP/IPv4) option.

Another dialog box will be opened and there just neglect the first set about the IP address (Keep as it is set) and click radio button of Use the following DNS server addresses: and enter as 8.8.8.8 in Preferred DNS server: and 8.8.4.4 in Alternate DNS server:

Now you can open your emulator whenever and you will get internet in the android emulators.

Answer 15

This was a problem for me last time the emulator updated itself and back then disabling other network adapters fixed it. Now it's cropped up again but the only adapter that is enabled is a single wifi one so I have nothing to disable.

The issue only reappeared after I updated via a prompt the emulator tools to 26.1.1. I uninstalled and reinstalled the emulator via the SDK Tools update tab and thankfully the only option when installing again right now is to install 26.0.3 (which seems to be working okay).

Moral of the story is to be very wary of emulator updates .

Answer 16

For me the problem was caused when I took my laptop home without restarting the emulator. From what I have read, when the emulator starts up it reads your PC's DNS settings and uses them. When I was on my home network, my work DNS settings were failing.
So yeah. Just restarting the emulator solved my problem.

Answer 17

I faced this problem after i kept my emulator ON while going from my home to a cafe. "Cold Boot Now" fixed the issue.

Answer 18

After 10 days of trouble, I just deleted everything from C:\Android\.android\ and deleted all created AVDs. Now internet seems to work fine.

Answer 19

closing the emulator and reopening worked for me

Answer 29

Solution for MacOS that does not use a custom DNS for your whole machine

Step 1

Locate the emulator executable Android Studio is using inside the Android SDK and rename it to emulator-original .

Mine is located /usr/local/share/android-sdk/emulator/emulator but it might vary based on individual setups.

Step 2

Add a new file called emulator in the place of the original file containing the following command (or using your DNS server of choice).

#!/bin/bash
$0-original "$@" -dns-server 8.8.8.8

Step 3

Make the new emulator file executable.

chmod +x emulator

Step 4

Restart the emulator using Android Studio.

Answer 31

Pro tips: using AVD with dnsmasq on Linux

To understand you to read Set up Android Emulator networking from Android Studio.

The loopback of the emulated device is 127.0.0.1 and the host loopback can be accessed from the emulated device from 10.0.2.2 .

At startup, the emulated device set its DNS nameserver by picking those from the host in /etc/resolv.conf .

But the point is, if you are using dnsmasq , you set nameserver 127.0.0.1 in /etc/resolv.conf` so the emulated device will hit it's own loopback where nothing is running instead of the host loopback where there is a DNS server running.

To solve that, add -dns-server when running AVD from the CLI.

For example:

• Cloudflare DNS: ~/Android/Sdk/emulator/emulator -avd Nexus_9_API_23 -dns-server 1.1.1.1
• Host's dnsmasq: ~/Android/Sdk/emulator/emulator -avd Nexus_9_API_23 -dns-server 1.0.2.2

2. second:connect to emulator wifi.

Answer 34

Try these steps once, they worked for me:

1. Disconnect your PC from the internet
2. Close the emulator while you are still disconnected
3. Again connect to the internet
4. Finally start your emulator again

Answer 35

As pointed by @osama buzdar, the DNS settings the emulator looks first might be specified in /etc/resolv.conf . In my case, as of macOS Catalina 10.15.7, there was 2 addresses in that file: the first one was a IPv6 and the second, IPv4 and for some reason the emulator was probably having trouble with the IPv6.

Then I edited the file ( sudo vi /etc/resolv.conf ) and moved the IPv4 up to be the first entry of the file, before the IPv6. Restarted the emulator and it worked.

Apple MacBook M1

None of the answers worked for me on a m1 mac, I was not even able to connect to localhost for the react-native development server.

The trick for me was to turn off the cellular data "T-mobile," then it would use AndroidWiFi for inte.net and everything worked fine.

Here's a screenshot of my working settings:

Answer 37

I had this also and I solved it by creating new android emulator virtual device and chosen Nexus 4 api 27. Before I was creating Pixel device api 28, and it was not working even after recreating device. So I tried totally different configuration and Android Emulator has internet connection as is expected. Other solutions did not work for me but I did no try it all.

Answer 38

For me the problem was my computer was connected to VPN. Once I disconnected that it started working in emulator.

Answer 39

For me on OSX, it was because of using a 3rd party VPN solution...it installs some sort of network hook that AVDs and Genymotion couldn't route through. Had to uninstall it for it work properly. Worked fine on some networks and not on others...was very weird..

Answer 40

I had the same problem on Windows 10. I just went to the Network & internet settings> Change adapter options> right-click on Wi-Fi and chose properties> Chose Internet protocol version 4 in the list and clicked properties> Turned on the "Use the following DNS server addresses" and filled the first part with "8.8.8.8" address . Problem solved!

Windows DNS settings are specified in the TCP/IP Properties window for the selected network connection.

Example: Changing DNS server settings on Windows 10

Go to the Control Panel. Click Network and Internet > Network and Sharing Center > Change adapter settings. Select the connection for which you want to configure Google Public DNS. For example:

To change the settings for an Ethernet connection, right-click the Ethernet interface and select Properties. To change the settings for a wireless connection, right-click the Wi-Fi interface and select Properties. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

Select the Networking tab. Under This connection uses the following items, select Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6) and then click Properties.

Click Advanced and select the DNS tab. If there are any DNS server IP addresses listed there, write them down for future reference, and remove them from this window.

Click OK.

Select Use the following DNS server addresses. If there are any IP addresses listed in the Preferred DNS server or Alternate DNS server, write them down for future reference.

Replace those addresses with the IP addresses of the Google DNS servers:

For IPv4: 8.8.8.8 and/or 8.8.4.4. For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844. For IPv6-only: you can use Google Public DNS64 instead of the IPv6 addresses in the previous point. Test that your setup is working correctly; see Test your new settings.

Repeat the procedure for additional network connections you want to change.

macOS DNS settings are specified in the Network window.

Example: Changing DNS server settings on macOS 10.15

Click Apple menu > System Preferences > Network. If the lock icon in the lower left-hand corner of the window is locked, click the icon to make changes, and when prompted to authenticate, enter your password. Select the connection for which you want to configure Google Public DNS. For example: To change the settings for a Wi-Fi connection, select Wi-Fi, and click Advanced. To change the settings for an Ethernet connection, select Built-In Ethernet, and click Advanced. Select the DNS tab. Click + to replace any listed addresses with, or add, the Google IP addresses at the top of the list: For IPv4: 8.8.8.8 and/or 8.8.4.4. For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844. For IPv6-only: you can use Google Public DNS64 instead of the IPv6 addresses in the previous point. Click OK > Apply. Test that your setup is working correctly; see Test your new settings. Repeat the procedure for additional network connections you want to change.

Linux In most modern Linux distributions, DNS settings are configured through Network Manager.

Example: Changing DNS server settings on Ubuntu

Click System > Preferences > Network Connections. Select the connection for which you want to configure Google Public DNS. For example: To change the settings for an Ethernet connection, select the Wired tab, then select your network interface in the list. It is usually called eth0. To change the settings for a wireless connection, select the Wireless tab, then select the appropriate wireless network. Click Edit, and in the window that appears, select the IPv4 Settings or IPv6 Settings tab. If the selected method is Automatic (DHCP), open the dropdown and select Automatic (DHCP) addresses only instead. If the method is set to something else, do not change it. In the DNS servers field, enter the Google Public DNS IP addresses, separated by a comma: For IPv4: 8.8.8.8 and/or 8.8.4.4. For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844. For IPv6-only: you can use Google Public DNS64 instead of the IPv6 addresses in the previous point. Click Apply to save the change. If you are prompted for a password or confirmation, type the password or provide confirmation. Test that your setup is working correctly; see Test your new settings. Repeat the procedure for additional network connections you want to change. If your distribution doesn't use Network Manager, your DNS settings are specified in /etc/resolv.conf.

Example: Changing DNS server settings on a Debian server Edit /etc/resolv.conf:

sudo vi /etc/resolv.conf

If any nameserver lines appear, write down the IP addresses for future reference.

Replace the nameserver lines with, or add, the following lines:

For IPv4:

nameserver 8.8.8.8
nameserver 8.8.4.4

For IPv6:

nameserver 2001:4860:4860::8888
nameserver 2001:4860:4860::8844

For IPv6-only, you can use Google Public DNS64 instead of the above IPv6 addresses.

Save and exit.

Restart any Internet clients you are using.

Test that your setup is working correctly; see Test your new settings.

One of the quick and easiest way to solve this is choose a device with API 29 or below , there is some issue on higher API for the inte.net. The DNS thing was not working for me, so I tried degrading the device API level, and chrome, etc. started working. My application however was able to use the inte.net as we were able to fetch the data from BackEnd on higher API but having chrome issues testing some other functionality.

For me, I went to the connectivity settings in emulator and disconnected Android WiFi . Then inside this, I pressed Forget Connection . Now again connecting to the same WiFi solved the issue. Quickest way to resolve this I think!

Answer 60

I've been having this issue for the past 8 hours, figuring out a way to solve it. It happened after my house had a power outage. My emulator would not longer connect to my pc's internet. I tried every solution here. The changing DNS to 8.8.8.8 worked, but I didn't want to route all my traffic through google.

What FINALLY worked was. I know this is insane, but unplugging my wifi router/modem. One quick unplug and replug fixed this issue. I TRIED EVERYTHING on this SO question and 5 other questions. I even redownloaded Android Studio and the Emulators. None of it worked. Try unplugging your router/modem.
