I have installed the new Android Studio
. Everything was working fine but when I try to create a new project it gets stuck at downloading Gradle
If you're using OS X, and it continues to hang indefinitely, I'd recommend shutting down Android Studio (may have to force kill), then going to your ~/.gradle directory on the console. You'll see a wrapper/dists directory there and whatever version of gradle AS is trying to download. Check the timestamp of the download underneath the randomly named subdirectory. If you see that it is never changing, most likely your download was interrupted and AS wasn't able to restart it properly and will not unless you delete everything below the dists directory and start over.
So, with AS shutdown delete everything below ~/.gradle/wrapper/dists and then try again with a new project in AS. You can check the progress of the gradle download file (it will end in .part) to make sure that it's growing. Give it plenty of time as it IS a large file.
That's what finally worked for me.
