Android emulator not able to access the internet

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 internet. 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 internet 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 internet. Below is an image of my emulator when I try to use Chrome to search for "Google".

Answer 1

go to your adapter setting and change the dns to 8.8.8.8 which is google's and it will work,it worked for me

Answer 2

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.

Finally, I had to delete the .android folder and create new one. It seems that the files got corrupted

Answer 4

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!

Answer 5

Reminder: the Android Emulator internet connection does not work if you turn on a VPN system on you computer.

Answer 6

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.
