I am new to Android studio I am not able to understand what error means nor i am able to find anything on internet. Pleas help me. Sorry for bad english.

Answer 1

I just encountered the same problem.

Please change your DNS server setting and reconnect to the Internet. Afterwards, try Gradle sync again.

Google Public DNS

For example, you can make use of the Google Public DNS, which is 8.8.8.8 and 8.8.4.4.

OpenDNS

OpenDNS is an alternative.

Answer 2

Just add this line in gradle setting so that your service can be update distributionUrl=https://services.gradle.org/distributions/gradle-2.2.1-all.zip

Answer 3

I think the site, https://services.gradle.org/distributions/ has wrongly configured ssl certificate issue. The certificate used for that domain is not a proper one for the domain name.

I think you should wait until Gradleware fixes it, and in the meantime, you can temporarily use Emanuel's workaround.

Answer 4

As a temporary workaround you may download Gradle over http instead of https.

Edit gradle/wrapper/gradle-wrapper.properties, that should be available at the root of your project, and change distributionUrl to:

distributionUrl=http\://services.gradle.org/distributions/gradle-2.2.1-all.zip
