Answer 1

Download gradle from:http://services.gradle.org/distributions/

choose the file such as gradle-4.1-rc-1-all.zip

Find your gradle directory in AndroidStudio setting-->Build,Execution,Deployment -->Gradle

Unzip the file to "(your gradle path)\wrapper\dists\gradle-4.1-all\bzyivzo6n839fup2jbap0tjew"

Answer 2

Ihave had the same problem. Finally I fixed it ussing an external gradle instalation. To make it you need to configure File->Settings->Build,Execution and deployments->Gradle Check -> Use local gradle distribution Select gradle home instalation.

If you are using an corporative connection, you also have to configure gradle proxy properties configuring or creating file gradle.properties in folder "/Users/user/.gradle":

#http proxy setup
systemProp.http.proxyHost=url
systemProp.http.proxyPort=port
systemProp.http.nonProxyHosts=*.nonproxyrepos.com|localhost

#https proxy setup
systemProp.https.proxyHost=url
systemProp.https.proxyPort=port
systemProp.https.nonProxyHosts=*.nonproxyrepos.com|localhost

That's all!
