make sure that you disable the proxy setting. settting > apperance and behaviour > Http Proxy > and select no proxy check box and check the connection after you select no proxy or auto detect proxy setting > the apply ok

Everyone: I Solved the problem like this. In Android Studio go to File menu and select the Invalidate Caches/Restart... I hope it will work for you. Thanks

Check your internet connection is stable or not. May be this will work with you

In my case issue occurred after following:

I selected proxy settings from Android Studio settings when I was working in a network behind a proxy. When I disconnected from that network and connected to home network which doesn't have a proxy, I removed the proxy settings from Android Studio, but gradle seemed to take the old proxy settings.

The problem was that gradle had also saved the proxy settings in following file when I set proxy settings in Android Studio, but it hasn't got removed when I removed proxy settings from Android Studio.

%HOME%\.gradle\gradle.properties

When I removed the proxy settings from this file, gradle sync worked again.

The problem is you are not able to download gradle from the host specified in gradle/wrapper/gradle-wrapper.properties

In my case this happened after I refactored the code using Idea. To get this working: 1. Be sure you can download the zip file at URL in the file mentioned above 2. If you can you may wanna check your proxy configuration or env vars

Android Plugin for Gradle HTTP proxy settings

For application-specific HTTP proxy settings, set the proxy settings in the build.gradle file as required for each application module.

apply plugin: 'com.android.application'

android {
    ...

    defaultConfig {
        ...
        systemProp.http.proxyHost=proxy.company.com
        systemProp.http.proxyPort=443
        systemProp.http.proxyUser=userid
        systemProp.http.proxyPassword=password
        systemProp.http.auth.ntlm.domain=domain
    }
    ...
}

For project-wide HTTP proxy settings, set the proxy settings in the gradle/gradle.properties file.

# Project-wide Gradle settings.
...

systemProp.http.proxyHost=proxy.company.com
systemProp.http.proxyPort=443
systemProp.http.proxyUser=username
systemProp.http.proxyPassword=password
systemProp.http.auth.ntlm.domain=domain

systemProp.https.proxyHost=proxy.company.com
systemProp.https.proxyPort=443
systemProp.https.proxyUser=username
systemProp.https.proxyPassword=password
systemProp.https.auth.ntlm.domain=domain

...

Please read Official Document Configuration

Go To: File --> Setting --> Build, Execution, Deployment --> Gradle, then tick the use local Gradle distribution, then set Gradle home by giving path to Gradle. Tick offline work.

Like so:

If you are using an http proxy server, revise the following proxy settings in "gradle.properties" file in your project's root folder. If not using proxy server, just delete those entries.

systemProp.http.proxyPort=8080
systemProp.http.proxyUser=UserName
systemProp.http.proxyPassword=Passw0rd
systemProp.https.proxyPassword=Passw0rd
systemProp.https.proxyHost=proxy.abc.com
systemProp.http.proxyHost=proxy.abc.com
systemProp.https.proxyPort=8080
systemProp.https.proxyUser=UserName

If you are using WAMP/XAMP server turn it off. This resolved my problem.

For some reason, using a shared machine, I couldn`t figure out where this proxy properties is comming from.

So a workaround to fix this is add in you project gradle.properties the following (empty properties). So It will override top hierarchy configuration:

systemProp.http.proxyPort=
systemProp.http.proxyUser=
systemProp.http.proxyPassword=
systemProp.https.proxyPassword=
systemProp.https.proxyHost=
systemProp.http.proxyHost=
systemProp.https.proxyPort=
systemProp.https.proxyUser=

Go to..

File > Settings > Appearance & Behavior > System Settings > HTTP Proxy Enable following option Auto-detect proxy settings

and press checkConnection button for test

Download a recent gradle release from gradle.org/releases Unzip the file and copy the gradle folder e.g. gradle 4.0 into C -- program files -- android -- android studio -- gradle. On your android studio goto file -- settings -- Build, Execution, Deployment --Build Tools -- Gradle and choose Use local gradle distribution, in the gradle home locate your gradle folder and click apply. Then click okay. This solved the problem for me. Your android studio might require a more recent gradle release, make sure you download a gradle that is compatible with your studio or latest releases.

Preferences --> Build, Execution, Deployment --> Gradle --> Android studio

I had the same problem. What worked for me was:

Go to File>Invalidate caches/restart>Invalidate and restart.

Hope it works for you too.

If that doesn't work, give your system access to internet and click on Help>Check for Updates. And update android studio to latest versions. All gradle along with plugins will be updated and i guess it should resolve the issue.
