Use the Android Gradle Plugin offline

This document describes how to use Android Studio with downloads of offline Android Gradle plugin and Google Maven repository dependencies.

Download and unzip offline components

If you haven’t already done so, download the offline components from the official Android Studio website: https://d.android.com/r/studio-offline/downloads .

After you have downloaded the offline components, unzip their contents into the following directory, which you might need to create if it doesn’t already exist: %USER_HOME%/.android/manual-offline-m2/.

To update these components, simply re-download the offline components, unzip their contents into your %USER_HOME%/.android/manual-offline-m2/ directory, and replace any files, as needed.

Include offline components in your Gradle project

After you download and unzip the offline components, you need to create a script to tell Gradle to use include the offline components you downloaded when it searches for your project’s Android Gradle plugin and Google Maven dependencies.

Note: This script applies to all Gradle projects you open on the workstation.

To create the script, proceed as described below. Keep in mind, you need to create and save this script only once, even after updating your offline components.

1. Create an empty text file with the following path and file name: %USER_HOME%/.gradle/init.d/offline.gradle.
2. Open the text file and include the following script:

def reposDir = new File(System.properties['user.home'], ".android/manual-offline-m2")
def repos = new ArrayList()
reposDir.eachDir {repos.add(it) }
repos.sort()

allprojects {
  buildscript {
    repositories {
      for (repo in repos) {
        maven {
          name = "injected_offline_${repo.name}"
          url = repo.toURI().toURL()
        }
      }
    }
  }
  repositories {
    for (repo in repos) {
      maven {
        name = "injected_offline_${repo.name}"
        url = repo.toURI().toURL()
      }
    }
  }
}

3. Save the text file.
4. (Optional) If you’d like to verify that the offline components are working as intended, remove the online repositories from your project’s build.gradle files, as shown below. After you’ve confirmed that your project builds correctly without these repositories, you can put them back into your build.gradle files.

buildscript {
    repositories {
        // Hide these repositories to test your build against
        // the offline components. You can include them again after
        // you’ve confirmed that your project builds ‘offline’.
        // google()
        // jcenter()
    }
    …
}
allprojects {
    repositories {
        // google()
        // jcenter()
    }
    ...
}
