Answer 1

please check your gradle wrapper, there are 2 gradle wrapper, one is in library folder, and one is in gradle folder. probably the version of both gradle wrapper is different. i solve my case by make them as a same version..

Answer 2

In my case, after I config kotlin for project I face this problem.

After 30 minutes try 'Auto proxy' and learn about proxy with no hope, I see suddenly I see

repositories {
    mavenCentral()
}

in the end of my build.gradle. Then I delete it and it working.
The most interesting is after it working, I put above line to gradle again but it still working. So maybe it is not a root problem, however I think it may bring some luck in some case.

Currently, I use Window and AndroidStudio 3.4.2

Answer 3

Also, check the internet connection and try again clean and build it's worked for me.

Answer 4

Restarting emulator worked for me.

Answer 5

I was also having the same problem. I tried the following and it's working for me:

Windows

Go to : File > Settings > Appearance & Behavior > System Settings > HTTP Proxy [Under IDE Settings] Enable following option Auto-detect proxy settings

Mac

Go to : Android Studio > Preferences > Appearance & Behavior.. etc

You can also use the test connection button and check with google.com to see if it works or not.

Answer 6

I was facing the same error even after trying every possible combination of proxy settings, invalidate cache and restart.

The error vanished as soon as I switched my internet connection from wifi to mobile hotspot. Strange.
