878 PointsGradle sync failed: Protocol family unavailable-
I am using Windows 10, just downloaded android studio 2.3.3 and manually installed Gradle 4.0.2 from gradle.org (JVM 1.8). I have also checked the installation by running the gradle -v command in command prompt. My problem is that the project is not getting built. I get an error from Android studio which states - Gradle 'FunFacts' project refresh failed: Error- Protocol family unavailable. I have also tried switching off my firewall but it makes no difference. Due to this I do not see a screen similar to the last one that is shown in this video i.e. FunFactsActivity.java. In fact I do not see java under app folder

There's some useful tips in this thread. That's not an error I've ever come across.

878 PointsHi Steve, I have followed the thread. The settings on my vmoption file were already set as per this thread i.e. -Djava.net.preferIPv4Stack=true. Still unable to Android Studio working.

Here's another thread that has an alternative suggested solution. Every other thread talks about IPv4 which clearly isn't the issue.
It may be worth an uninstall and trying again.
Sorry I can't be of any use! I've not come across this problem before but hope to learn how to fix it should other students suffer the same problem.
Steve.
