Unable to resolve host “” No address associated with hostname

Question

I tried following this tutorial: Getting Data from the Web

I tried implementing it on Android 3.0, the latest platform for tablets, however, I get this error: \"

Answer 1

Are you able to reach that url from within the built-in browser?

If not, it means that your network setup is not correct. If you are in the emulator, you may have a look at the networking section of the docs.

If you are on OS/X, the emulator is using "the first" interface, en0 even if you are on wireless (en1), as en0 without a cable is still marked as up. You can issue ifconfig en0 down and restart the emulator. I think I have read about similar behavior on Windows.

If you are on Wifi/3G, call your network provider for the correct DNS settings.

Answer 2

Restarting the emulator works in some scenario.

Answer 3

if you have USB internet like me the emulator seems to dislike connection being turned on and off so you may need to restart the emulator

Answer 4

Also, make sure that your device isn't on airplane mode and/or that data usage is enabled.

Answer 5

I had the same issue with the Android 10 emulator and I was able to solve the problem by following the steps below:

1. Go to Settings → Network & internet → Advanced → Private DNS
2. Select Private DNS provider hostname
3. Enter: dns.google
4. Click Save

With this setup, you URL should work as expected.
