The project gets build successfully if we select Ripple - IOS, however for Android - Device the build shows following errors:

You might be seeing this error if your developer PC is behind a network proxy. If that's the case, then make sure you're first working with at least Update 8 of the Visual Studio Tools for Apache Cordova, which improve support for network proxies.

Also, from another post I found, you may try customizing your proxy settings for Gradle. The answer from the referenced post mentions creating a gradle.properties file, using the following code as a guide for your specific proxy settings:

systemProp.https.proxyHost=www.somehost.org
systemProp.https.proxyPort=8080
systemProp.https.proxyUser=userid
systemProp.https.proxyPassword=password
systemProp.https.nonProxyHosts=*.nonproxyrepos.com|localhost

(Learn more about these settings in the official Gradle docs)

Since you're using Visual Studio, your best practice here is to actually place the gradle.properties file in the res\native\android folder of your project. Upon build, that file will then be copied into the platforms\android folder used by Cordova.
