Finished with error: Please review your Gradle project setup in the android/ folder.

When i click on the links it opens my browser and downloads the file.

According to the error, you are behind proxy and not to configure proxy for Gradle/Android Studio:

Received status code 407 from server: Proxy Authentication Required

You need to add this configuration to gradle.properties as explained in the documentation:
Accessing the web through a HTTP proxy

You can edit gradle.properties in each project you have or in Gradle installation directory.

I tried this, but still it gives me the same error. When i test the connection with the .pom url in android studio proxy settings which are the same as in the gradle.properties it gives me “Connection successful”.
