In this issue, the editor will bring you about how to transfer the Eclipse project to Android Studio. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

This guide contains some basic information you need to know before you transfer an Eclipse project to Andorid Studio.

Say goodbye to WorkSapces and Sub-Projects

In Eclipse, you may be familiar with the concept of "Workspace". There may even be one such Android project that contains various member projects and files compiled into ".jar" that will be included in the resulting app. In Andorid Studio, project is replaced by "Modules" and "Library Modules".

Modules

Modules is "an independent functional unit that can be run, tested, and debugged independently", similar to the concept of Eclipse project, but with a few differences.

Each Module needs to have its own Gradle build file (it will be automatically generated for you when you create a new Module, and you need to create it yourself when you import an Eclipse project). These Gradle files contain some very important contents.

For example, the supported Android version and what the project depends on, as well as other important data in the Android project.

As on Eclipse, some Modules may be "Library Modules" and functionally the same as "Library projects".

Improved interface design

Android Studio has an improved design window interface, where you can see your design interface and related elements. There is a similar interface design window in Eclipse, so it shouldn't shock you too much. In Eclipse, this window provides views and visible actions, as well as distribution mechanisms, multitasking, and information filtering associated with resource files.

Includes support for jar files

As encountered in Eclipse, you will often need to use JAR files developed by third parties. However, you now need to get used to adding these .jar dependency packages to your Gradle. Right-click the .jar file in the "libs" directory, and then select "Add As Library". In this way, the Jar file you choose will automatically be added as a Gradle dependency package in your corresponding Moule.

Add Module dependency

Like Eclipse, one Module may depend on other Module. Follow these steps to establish a dependency between the two modules, and then the Android Studio will automatically generate the required Gradle elements.

Migrate to Android Studio

To read about how to migrate a project from Android Studio to Eclipse, you can learn the process in my article, "Import or Export an existing Elipse Project to AndoridStudio." There are a lot of potential problems that may occur in the article, so I won't go into more details here.

Basic knowledge of Gradle

The addition of Gradle will be an obstacle for you to switch to Android Studio. Here are a few basics you need to know:

Your Android Studio project will have a settings.gradle file about the entire project.

The settings.gradle file includes references to all modules in the project, which is automatically updated when you import or create a new module.

Each Andorid Studio module will have its own build.gradle file.

If one Module depends on another module up, you need to add this dependency to the build.gradle file of the dependent part.

If your Module needs a jar file, the jar must be listed in Module's build.gradle file.

You can list the remote dependencies you want to add to your project in module's build.gradle file.

Sometimes you need to modify these gradle files manually.

More information about Gradle can be found here.

Usage test

Support for JUnit unit testing makes Andorid Studio more complete. For more information, please refer to here. Creating and running a unit test includes creating a new unit test class and adding them to the project's run configuration. Follow the link for more details. Popular testing frameworks such as Roboguice are not fully supported yet, but I wouldn't be surprised if they show up in the near future.

Import remote dependencies through Maven

Android Studio allows you to import remote library files from Maven Central. Browse through remote library files in Maven Central that may be of interest to you, and then follow these instructions to make sure these dependencies are automatically downloaded at compile time.
