// This settings file configures an Android project for substituting a
// local Application Services and/or Glean.
//
// For convenience, this file reads the `autoPublish.*` properties from
// `$topsrcdir/local.properties`, so that you only need to set them once
// for all Android projects.
//
// You can also set or override these properties on a per-project basis,
// by setting them in `$topsrcdir/mobile/android/{project}/local.properties`,
// if you want to only substitute App Services or Glean for a specific project,
// or to substitute different versions for different projects.
//
// This settings file configures the build to automatically publish the
// contents of your Application Services and Glean checkouts to the
// Maven local repository. Any dependencies are then substituted to use
// the locally published versions.
