To make a Moodle plugin compatible with the Moodle Mobile App, you need to create a db/mobile.php file to declare handlers for app delegates and an output class in classes/output/mobile.php to render content using Ionic components.

The db/mobile.php file is used in Moodle App plugin development to declare handlers for different app delegates, allowing the Moodle Mobile App to recognize and interact with your custom plugin's features and pages.

You render custom plugin content in the Moodle App by creating an output class at classes/output/mobile.php, which defines how your plugin data is displayed using Ionic components for a native mobile experience.

Yes, web service integration is required when extending the Moodle App with a custom plugin to fetch and manipulate data between the mobile application and your Moodle site's backend database.

You can display custom assignment details within the Moodle App by following the plugin development guide to expose your custom Moodle plugin content and submission options directly through mobile handlers and Ionic output rendering.

The Moodle App plugin development guide focuses on using Ionic components for rendering content via classes/output/mobile.php, meaning your plugin's mobile interface is constrained to the UI elements and web service interactions supported by the Moodle App framework.
