Android Studio from Eclipse

Question

I'm trying to migrate my Eclipse ADT project to Android Studio and it's not working.

Here is the thing:

• My project include android support v4 and v7, and play services and other .jars

What do I use:

• ADT 22.0.1
• Android Studio 0.3.6

What have I done:

• Set my ANDROID_HOME var to my android sdk path
• Exported ADT project to Gradle (as explained on Android website)
• Replace some parameters, like absolute path to relative path (see below in gradles)
• Some Stack Overflow answers tricks (but not useful for now)

Here are the Gradle specs:

• settings.gradle

  include ':Project'

• gradle\wrapper\gradle-wrapper.properties

  distributionBase=GRADLE_USER_HOME
  distributionPath=wrapper/dists
  zipStoreBase=GRADLE_USER_HOME
  zipStorePath=wrapper/dists
  distributionUrl=http\://services.gradle.org/distributions/gradle-1.8-all.zip
  

• Project\build.gradle

  buildscript {
      repositories {
          mavenCentral()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:0.6.+'
      }
  }
  apply plugin: 'android'
  
  dependencies {
      compile 'com.android.support:support-v4:18.0.0'
      compile 'com.android.support:appcompat-v7:18.0.+'
      compile 'com.google.android.gms:play-services:3.1.36'
      compile fileTree(dir: 'libs', include: '*.jar')
  }
  
  android {
      compileSdkVersion 17
      buildToolsVersion "19.0.0"
  
      sourceSets {
          main {
              manifest.srcFile 'AndroidManifest.xml'
              java.srcDirs = ['src']
              resources.srcDirs = ['src']
              aidl.srcDirs = ['src']
              renderscript.srcDirs = ['src']
              res.srcDirs = ['res']
              assets.srcDirs = ['assets']
          }
  
          instrumentTest.setRoot('tests')
      }
  }
  

Now when I (try to) import the project in Android Studio, I got an error message:

Could not execute build using Gradle distribution 'http://services.gradle.org/distributions/gradle-1.8-all.zip'. Task 'wrapper' not found in project ':Project'.

What now ?:

How can I progress this further?

Answer 1

This is not a great solution, is not a clean one, but it worked for me: Create a new project from scratch and copy all the files do you need from eclipse to android studio. This was the way I did it and it worked. It is a pain in the ass to migrate from eclipse to android studio and vice-versa

Answer 2

Update your Android Studio from Help > "Check For updates"

Answer 3

In Project Settings, go to Gradle and select "Use default gradle wrapper (recommended)". Be sure to do this for every project at the top of that dialog window.

If the option is disabled for any of the projects, what I had to do to enable it was to copy the gradle/wrapper files (gradle-wrapper.jar and gradle-wrapper.properties) into a gradle/wrapper subdirectory under each project.

Answer 4

Open eclipse and right click on your project. Then Select Export. It will open in which you have to click on Android then select generate Gradle build file.
