Make sure that your gradle version is defined properly.
It seems that this project was on another PC and you imported it on your computer. I think that probably a gradle version conflict occurred and you have two options:
one is to let android studio download gradle version specified in TlaProject (gradle 2.4)
another solution is to edit app level 'build.gradle' file and change its version to a version which is available on your machine (to see which version is available on your system, please check 'gradle' folder inside installation folder of android studio)

My problem was solved by updating the version of android studio .

Android Studio error: This folder does not belong to a gradle project (Jsoup.jar)

Since last android studio (1.1.0) update I have one issue with Jsoup(1.8.1) Gradle and it compilation.
When I import jsoup.jar in the projects I receive a message that said
To fix this problem. I have tried:
-I try click on "Add now..." but dont fix the issue.
-Clean project.
-Rebuild project.
-Close and open Android Studio.
Nothing have worked.
Any ideas?
Thanks.
Update 1: I have updated to android-studio Beta(1.2) and now works fine. But i want use android-studio Stable version.

I had the exact same problem. On Mac OS X 10.10.3, upgading to version 1.2.2 of Android Studio solved this problem for me. I used option-return key press while hovering over the class name I wanted to reference and that caused Android Studio to add the appropriate import. Auto-completion seems to work as well in the IDE.

Eclipse Gradle export of Android project does nothing

I'm trying to export my Android project from Eclipse (ADT 22.2.1) using the Gradle plugin.
I select my project in the initial Gradle dialog, click next
My project appears along with Android dependencies.
When I click on Finish, I can barely see a message "Creating Gradle Build files" BUT I never get a confirmation of Success. And build.gradle or settings.gradle ARE NOT in my projects root directory.
I can select each of the dependency libraries and they complete successfully
Any suggestions?

I faced the same problem, my solution was install the lastest Eclipse from their page, (i was using Juno, now with Kepler didn't have that problem), and Android ADT plugin link. Seems that they have breaked compatibility with older eclipse version in newer ADTs
An ankward one, but...at least it works
You can try it "the hard way", creating required files (build.gradle, gradle wrapper et al) by hand, but you will got a lot of mistakes, didn't worth the time spent.
EDIT : Extracted from Android Tools Tech Docs : Open the project in Eclipse, and from there, export the project. NOTE: Make sure you are using the latest possible version of Eclipse since we have fixed issues related to export recently.

Gradle build errors with Android Studio

When I try to build my project in Android Studio I get the following error, using the gradle plugin provided with the download (v 1.6):
The specified Gradle installation is not supported by this tooling API version (1.6, protocol version 4)
When I downgrade to gradle 1.3, 1.4 or 1.5, I get this error:
Gradle: : java.lang.ClassNotFoundException: org.gradle.tooling.provider.model.ToolingModelBuilderRegistry
The project was originally created in Eclipse, the exported using the build gradle file option, then imported into Android Studio.
Does anyone know what I can do to fix these issues? Many thanks.

I had a similar problem and I believe that it was caused by having multiple versions of gradle on my machine. The solution I found was to use the script that Android Studio creates in your project folder (either gradlew (MacOs/Unix) or gradlew.bat (Windows)):
./gradlew assemble
This causes the correct version of gradle to be run - i.e. the version that was shipped with Android Studio.
I haven't tried creating a project within Eclipse, so I'm not sure if these scripts are created when creating your project in that way.

I think the problem is with the way Eclipse 22 exports the project. In the end the way I got my project transferred over was to create a new project in Android Studio and copy over the files from my Eclipse project into the appropriate directories in the new project.
The directory structure of projects in Android Studio is very different to the structure in Eclipse, and there are several files created when you start a new project which you don't get when importing a project from Eclipse (e.g. gradlew.bat, settings.gradle).

I also had this problem which can indeed be worked around with Mark's suggestion of using ./gradlew assemble.
However, this does not help you run Make Project from within Android Studio.
To do that, I had to go to Preferences / Gradle / Use local gradle distribution
and select any random (but NOT gradle) folder inside the project folder.
You might notice that this is marked as an invalid location, but you can ignore that, it seems...
Not a great solution, but it works.
