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

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

Available Commands

  • supply: update an app with metadata, a build, images and screenshots
  • supply init: download metadata for an existing app to a local directory
  • supply --help: 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

supply --apk path/to/app.apk

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

To gradually roll out a new build use

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

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

Images and Screenshots

After running 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.

Here you can supply images with the following file names (extension can be png, jpg or jpeg):

  • featureGraphic
  • icon
  • promoGraphic
  • tvBanner

And you can supply screenshots by creating directories with the following names, containing PNGs or JPEGs (image names are irrelevant):

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

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. 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).
