How do you import an Eclipse project into Android

Question

Using "Import Project" in Android Studio for an Eclipse project used to change the project structure and generate Gradle files, but right now (I'm using AS 0.5.3) it's only generating IDEA files (.iml, .idea) but not Gradle and it's not touching the file structure either.

How do you import an Eclipse project into Android Studio now?

Update: Trying to export gradle files in Eclipse won't export them for the app, it doesn't show up as a module in Android Studio either.

Answer 1

Try these steps: 1- click on Import project (Eclipse, ADT, ...)

2- Choose main directory of your Eclipse project

3- Keep the defaults. The first two options is for changing jar files into remote libraries (dependencies). It mean while building Android studio try to find library in local system or remote repositories. The last option is for showing only one folder as app after importing.

4- Then, you will see the summary of changes

5- Then, if you see Gradle project sync failed, you should go to project view (top left corner). Then, you should go to your project-> app and open build.gradle.

6- Then, you should change your compilesdkVersion and targetsdkVersion to your current version that you see in buildToolsVersion (mine is 23). For example, in my project I should change 17 to 23 in two places

7- If you see an error in your dependencies, you should change the version of it. For example, in my project I need to check which version of android support library I am using. So, I open the SDK manager and go to bottom to see the version. Then, I should replace my Android studio version with my current version and click try again from top right corner

I hope it helps.

Export from Eclipse

1. Update your Eclipse ADT Plugin to 22.0 or higher, then go to File | Export

2. Go to Android now then click on Generate Gradle build files, then it would generate gradle file for you.

   

3. Select your project you want to export

   

4. Click on finish now

   

Import into Android Studio

1. In Android Studio, close any projects currently open. You should see the Welcome to Android Studio window.

2. Click Import Project.

3. Locate the project you exported from Eclipse, expand it, select it and click OK.

Answer 3

Stop installing android studio 3.0.1 and go back 2.3.3 ( Stable version) . Check for the stable version and you can find them a lot

All you have to do uninstall and go back to the other version. Yes it asks to create gradle file seperately which is completely new to me!

Failure is the stepping stone for success..

In addition to the answer by Scott Barta above, you may still have import problems if there are references to Eclipse workspace library files, with e.g.

/workspace/android-support-v7-appcompat

being a common one.

In this case the import will halt until you provide a reference (and if you've cloned from a git repo, it probably won't be there) and even pointing to your own install (e.g. something like /android-sdk-macosx/extras/android/m2repository/com/android/support/appcompat-v7) won't be recognised and will halt the import, leaving you in no-man's land.

To get around this, look for refs in the project.properties or .classpath files that came in from the Eclipse project and remove/comment them out, e.g.

<classpathentry combineaccessrules="false" kind="src" path="/android-support-v7-appcompat"/>

That will get you past the import stage and you can then add these refs in your build.gradle (Module:app) as indicated in the Android tutorial, like below:

dependencies {
    compile 'com.android.support:appcompat-v7:22.2.0'
}

Here is a simpler way to migrate:

Start off with a sample Android Studio project. Open android studio and create a new project (or) just download a ‘sample’ studio project here: https://github.com/AppLozic/eclipse-to-android-studio-migration. Now, open the downloaded project in Android Studio by following the below instructions.

Import eclipse project modules into Android Studio. Select File -> New -> Import Module Image title

Next, select the path of the eclipse project and import the modules. In case, if you see the message “Failed to sync Gradle project,” then click on “Install Build Tools and sync project…”

Now, remove the sample project modules by following the below simple steps:

Open settings.gradle and remove “include ‘:app’” Right click on “app” module and “Delete” it. Now, what we have is the Eclipse project open in Android studio with the Gradle build.
