Migrate from AsyncTask to other concurrency API

The Issue

Google has deprecated AsyncTask API since SDK API Level 30 -Android 11-. They are suggesting to use java.util.concurrent or Kotlin. I would add MIT-licensed Parse Bolt to the list of possibilities; it allows to chain tasks and act differently depending on the way certain task finishes. Bolt has been without updates since 2019 and I don't know if they are using AsyncTask internally.

If I was to choose, I would go with Java APIs for simple tasks and Bolt for those which should be chained. Bolt is also available for iOS if consistency for both source codes is preferred.

Internal Use

Acceptance Criteria

Definition of Done

• Tested against acceptance criteria
• Tested against the assumptions of the user story
• The project builds without errors
• Unit tests are written and passing
• Tests on devices/browsers listed in the issue have passed
• QA performed & issues resolved
• Refactoring completed
• Any configuration or build changes documented
• Documentation updated
• Peer Code Review performed

Start by locating the Android code that uses the deprecated AsyncTask API, then compare the proposed java.util.concurrent and Kotlin alternatives, including whether Parse Bolt is suitable. Done means the migration choice is implemented across the affected code, the project builds without errors, unit tests pass, and device testing and documentation are updated.
