Publish app artifacts to App Center

How to upload an apk or ipa file to App Center in a Flutter workflow editor post-build script

As a custom build step, Codemagic can publish your app artifact to App Center using the App Center Command Line Interface. An App Center API token is required for publishing. It is advisable to create a new token for use on Codemagic, see the commands related to API tokens here or manage your tokens in App Center settings.

  1. Add your App Center API token to Codemagic as a secure environment variable with the name APP_CENTER_TOKEN.
  2. In your app settings, expand the step between Build and Publish and add the respective post-build script.

Example script for publishing apk

#!/usr/bin/env zsh

echo 'Installing App Center CLI tools'
npm install -g appcenter-cli

echo "Find build artifacts"
apkPath=$(find build -name "*.apk" | head -1)
echo "Found apk at $apkPath"

if [[ -z ${apkPath} ]]
then
    echo "No apks were found, skip publishing to App Center"
else
    echo "Publishing $apkPath to App Center"
    appcenter distribute release \
        --group Collaborators \
        --file "${apkPath}" \
        --release-notes 'App submission via Codemagic' \
        --app <username_or_organization>/<application_identifier> \
        --token "${APP_CENTER_TOKEN}" \
        --quiet
fi

Example script for publishing ipa

#!/usr/bin/env zsh

echo 'Installing App Center CLI tools'
npm install -g appcenter-cli

echo "Find build artifacts"
ipaPath=$(find ~/ipas -name "*.ipa" | head -1)
echo "Found ipa at $ipaPath"

if [[ -z ${ipaPath} ]]
then
    echo "No ipas were found, skip publishing to App Center"
else
    echo "Publishing $ipaPath to App Center"
    appcenter distribute release \
        --group Collaborators \
        --file "${ipaPath}" \
        --release-notes 'App submission via Codemagic' \
        --app <username_or_organization>/<application_identifier> \
        --token "${APP_CENTER_TOKEN}" \
        --quiet
fi

This way, you can use Codemagic to automate the publishing of your Android or iOS app to App Center.
