Upload metadata, screenshots and binaries to Google Play (via supply)

Command line tool for updating Android apps and their metadata on the Google Play Store

supply uploads app metadata, screenshots, binaries, and app bundles to Google Play. You can also select tracks for builds and promote builds to production.

FeaturesSetupQuick StartCommandsUploading an APKUploading an AABImages


  • Update existing Android applications on Google Play via the command line
  • Upload new builds (APKs and AABs)
  • Retrieve and edit metadata, such as title and description, for multiple languages
  • Upload the app icon, promo graphics and screenshots for multiple languages
  • Have a local copy of the metadata in your git repository
  • Retrieve version code numbers from existing Google Play tracks


Setup consists of setting up your Google Developers Service Account

Tip: If you see Google Play Console or Google Developer Console in your local language, add &hl=en at the end of the URL (before any #...) to switch to English.

  1. Open the Google Play Console
  2. Click Account Details, and note the Developer Account ID listed there
  3. Click SetupAPI access
  4. Click the Create new service account button
  5. Follow the Google Cloud Platform link in the dialog, which opens a new tab/window:
    1. Click the CREATE SERVICE ACCOUNT button at the top of the Google Cloud Platform Console
    2. Verify that you are on the correct Google Cloud Platform Project by looking for the Developer Account ID from earlier within the light gray text in the second input, preceding .iam.gserviceaccount.com. If not, open the picker in the top navigation bar, and find the one with the ID that contains it.
    3. Provide a Service account name and click Create
    4. Click Select a role, then find and select Service Account User, and proceed
    5. Click the Done button
    6. Click on the Actions vertical three-dot icon of the service account you just created
    7. Select Manage keys on the menu
    8. Click ADD KEY -> Create New Key
    9. Make sure JSON is selected as the Key type, and click CREATE
    10. Save the file on your computer when prompted and remember where it was saved to
  6. Return to the Google Play Console tab, and click DONE to close the dialog
  7. Click on Grant Access for the newly added service account at the bottom of the screen (you may need to click Refresh service accounts before it shows up)
  8. Choose the permissions you'd like this account to have. We recommend Admin (all permissions), but you may want to manually select all checkboxes and leave out some of the Releases permissions such as Release to production
  9. Click Invite user to finish

You can use fastlane run validate_play_store_json_key json_key:/path/to/your/downloaded/file.json to test the connection to Google Play Store with the downloaded private key. Once that works, add the path to the JSON file to your Appfile:


The path is relative to where you normally run fastlane.

Migrating Google credential format (from .p12 key file to .json)

In previous versions of supply, credentials to your Play Console were stored as .p12 files. Since version 0.4.0, supply now supports the recommended .json key Service Account credential files. If you wish to upgrade:

  • follow the Setup procedure once again to make sure you create the appropriate JSON file
  • update your fastlane configuration or your command line invocation to use the appropriate argument if necessary. Note that you don't need to take note nor pass the issuer argument anymore.

The previous p12 configuration is still currently supported.

Quick Start

Before using supply to connect to Google Play Store, you'll need to set up your app manually first by uploading at least one build to Google Play Store. See fastlane/fastlane#14686 for more info.

  • cd [your_project_folder]
  • fastlane supply init
  • Make changes to the downloaded metadata, add images, screenshots and/or an APK
  • fastlane supply

Available Commands

  • fastlane supply: update an app with metadata, a build, images and screenshots
  • fastlane supply init: download metadata for an existing app to a local directory
  • fastlane action supply: show information on available commands, arguments and environment variables

You can either run supply on its own and use it interactively, or you can pass arguments or specify environment variables for all the options to skip the questions.

Uploading an APK

To upload a new binary to Google Play, simply run

fastlane supply --apk path/to/app.apk

This will also upload app metadata if you previously ran fastlane supply init.

To gradually roll out a new build use

fastlane supply --apk path/app.apk --track beta --rollout 0.5

To set the in-app update priority level for a release, set a valid update priority (an integer value from 0 to 5) using option in_app_update_priority

fastlane supply --apk path/app.apk --track beta --in_app_update_priority 3

Expansion files (.obb)

Expansion files (obbs) found under the same directory as your APK will also be uploaded together with your APK as long as:

  • they are identified as type 'main' or 'patch' (by containing 'main' or 'patch' in their file name)
  • you have at most one of each type

If you only want to update the APK, but keep the expansion files from the previous version on Google Play use

fastlane supply --apk path/app.apk --obb_main_references_version 21 --obb_main_file_size 666154207


fastlane supply --apk path/app.apk --obb_patch_references_version 21 --obb_patch_file_size 666154207

Uploading an AAB

To upload a new Android application bundle to Google Play, simply run

fastlane supply --aab path/to/app.aab

This will also upload app metadata if you previously ran fastlane supply init.

To gradually roll out a new build use

fastlane supply --aab path/app.aab --track beta --rollout 0.5

To set the in-app update priority level for a release, set a valid update priority (an integer value from 0 to 5) using option in_app_update_priority

fastlane supply --aab path/app.aab --track beta --in_app_update_priority 3

Images and Screenshots

After running fastlane supply init, you will have a metadata directory. This directory contains one or more locale directories (e.g. en-US, en-GB, etc.), and inside this directory are text files such as title.txt and short_description.txt.

Inside of a given locale directory is a folder called images. Here you can supply images with the following file names (extension can be png, jpg or jpeg):

  • featureGraphic
  • icon
  • promoGraphic
  • tvBanner

You can also supply screenshots by creating directories within the images directory with the following names, containing PNGs or JPEGs:

  • phoneScreenshots/
  • sevenInchScreenshots/ (7-inch tablets)
  • tenInchScreenshots/ (10-inch tablets)
  • tvScreenshots/
  • wearScreenshots/

You may name images anything you like, but screenshots will appear in the Play Store in alphanumerical filename order. Note that these will replace the current images and screenshots on the play store listing, not add to them.

Changelogs (What's new)

You can add changelog files under the changelogs/ directory for each locale. The filename should exactly match the version code of the APK that it represents. You can also provide default notes that will be used if no files match the version code by adding a default.txt file. fastlane supply init will populate changelog files from existing data on Google Play if no metadata/ directory exists when it is run.

Track Promotion

A common Play publishing scenario might involve uploading an APK version to a test track, testing it, and finally promoting that version to production.

This can be done using the --track_promote_to parameter. The --track_promote_to parameter works with the --track parameter to command the Play API to promote existing Play track APK version(s) (those active on the track identified by the --track param value) to a new track (--track_promote_to value).

Retrieve Track Release Names & Version Codes

Before performing a new APK upload you may want to check existing track version codes or release names, or you may simply want to provide an informational lane that displays the currently promoted version codes or release name for the production track. You can use the google_play_track_version_codes action to retrieve existing version codes for a package and track. You can use the google_play_track_release_names action to retrieve existing release names for a package and track. For more information, see the fastlane action google_play_track_version_codes and fastlane action google_play_track_release_names help output.

To show the documentation in your terminal, run

fastlane action upload_to_play_store


It is recommended to add the above action into your Fastfile, however sometimes you might want to run one-offs. To do so, you can run the following command from your terminal

fastlane run upload_to_play_store

To pass parameters, make use of the : symbol, for example

fastlane run upload_to_play_store parameter1:"value1" parameter2:"value2"

It's important to note that the CLI supports primitive types like integers, floats, booleans, and strings. Arrays can be passed as a comma delimited string (e.g. param:"1,2,3"). Hashes are not currently supported.

It is recommended to add all fastlane actions you use to your Fastfile.

Source code

This action, just like the rest of fastlane, is fully open source, view the source code on GitHub
