To upload your app, paste your API Key on the top bar of the window. To know where to get it, you can follow this guide: How to get your API Key.

Then, select the files you need to upload (.apk and .obb) and click "Upload".

Fastlane Plugin

To use the Fastlane plugin, start by installing Fastlane in your project’s directory. To do this, run the following commands:

  • brew install fastlane
  • fastlane init

Then, install the Catappult plugin by running "fastlane add_plugin catappultuploader" command. To install all the plugin dependencies, add this two lines to your Gemfile:

  • gem "net-http-uploadprogress"
  • gem "ruby-progressbar"
    And then run "bundler install" command.

Create the Catappult lane
After the previous two instalations, create a new lane on the Fastfile to use the Catappult uploader. The "supply_folder" variable is optional, the default value is the release folder in the current Android Studio project.
Here is an example:

lane :catappult do






Run the lane
Now, you run "bundle exec fastlane catapult" and it is done.
