I set up git in Android Studio
http://maxrohde.com/2014/08/18/import-github-project-to-android-studio/
Then imported this project
https://github.com/GautamGupta/Simple-Android-OCR
The following error was displayed:
Migrate Project to Gradle?
This project does not use the Gradle build system. We recommend that you migrate to using the Gradle build system.
What can I do to fix this?
That project hasn't been modified in two years, really four for most of the project, so it uses the older project layout and was very likely developed using Eclipse rather than Android Studio.
Here is the Google reference for migrating a project from Eclipse to Android Studio:
https://developer.android.com/sdk/installing/migrate.html
An option if simply importing doesn't work is to install Eclipse and do an export from there to Android Studio. While you could just work in Eclipse it is deprecated for Android development and you'll find many more up-to-date resources for Android Studio.
How do you import an Eclipse project into Android Studio now?
Android Studio's default build system is Gradle. That GiftHub project is not using Gradle build system. Probably created from Eclipse (Ant build system)
So when you open a project that does not use Gradle build in Android Studio, it will ask to convert the Project to Gradle based build. You just give yes on the popup, it will take care of everything.

here it explains solutions for gradle errors
That's not an error!
The recommended build system for android projects is gradle.
But the author of this project in github did it using only eclipse without any special build system.
You just need to answer "yes" to that popup message and Android studio will convert the project to use gradle

For example this project. I see it has Gradle files, but a quick search says Eclipse has a Gradle plugin as well.

The Android build system is built on top of gradle:
https://developer.android.com/tools/building/plugin-for-gradle.html
So that means that just plain gradle is not enough to build an Android project.
As ADT never used gradle and Google has ended Eclipse support, you can be reasonably confident that an Android gradle project was made using Android Studio.
Gradle is a building tool. It has plugins for Eclipse, IntelliJ, Android Studio and Netbeans. So you won't be able to tell which IDE an Android project is made with from just a gradle file. Some project structures vary, for Eclipse projects and IntelliJ ones, you can find easily differences between them if you are familiar with both. But some are not explicitly, for IntelliJ projects and Android Studio ones.
BTW, do IDEs matter? The App you are building does, I am afraid.
Android Studio, which is developed based on IntelliJ. It uses gradle to build the project.
If a project contains .classpath or .project, it should be made by Eclipse. Or it should be made by android studio. A project made by android studio can not be imported into eclipse.
I didn't know how to use the gradle.I am downloaded the gradle in this link. https://www.gradle.org/downloads
Right now I am using the Android eclipse.Let me know gradle would be used in Android eclipse or Android Studio?
What about the installation process in gradle to run the project?
Android studio is flexible Gradle-based build system. It contains gradle by default. See this: https://developer.android.com/sdk/installing/studio.html
For eclipse you can use plugin. Here's a link: http://gradle.org/docs/current/userguide/eclipse_plugin.html
I have an Android project created in Android Studio. It works fine in Android Studio, IDEA and build machine.
Now we have several new developers who work in Eclipse and I can't set it up. Is it possible to convert gradle(android studio) project to Eclipse IDE?
You'll have to maintain the build separately in both Gradle and Eclipse; Eclipse can't use the Android Gradle builder natively. It's on our list of things to implement but we don't have a roadmap for it yet.
Things will go easiest if you use an Eclipse-like directory structure and adapt the Gradle build file to work with it. See Maintaining directory structure during Android Studio import for advice.
Use Eclipse Compatibility Mode in Android Studio and Idea.
Or
Use Gradle and the new Build system in Eclipse: Is there any way to integrate Eclipse with Gradle in Android project?
I have a project that was originally from IntelliJ.
I followed the instructions below.
http://tools.android.com/tech-docs/new-build-system/migrating-from-intellij-projects
I'm not sure what to do next. When I load my project in Android Studio it still asks if I want to migrate to gradle. What did I miss?
I am able to use Gradle in the command prompt to build my project, so I assume I just need to tell Android Studio to use Gradle instead of Ant.
I next imported my existing project and it recognized it as a gradle project. I also had to change the gradle version in the gradle.build file to work with the newer version of 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.
