Importing a new LibGDX project into Android Studio, stuck in Gradle Build. First start

Question

I went to the libGDX website and uploaded the gdx-setup.jar file.
I opened it, set it up and clicked generate. He generated the gradle project successfully.
 Then I went to Android Studio -> "Open an existing project" -> pointed to a new libgdx gradle project.
But now he is stuck in the "Building" gdxgame 'gradle project information. "

I select the file in the root folder "build.gradle". Please tell me what is the problem?
