See [Changes files](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/guides/committing-changes.md#changes-files) for more information. - [x] Input data is properly validated, `SELECT *` is avoided, SQL injection is prevented (using placeholders for values in statements), JS inline code is prevented especially for url redirects, and untrusted data interpolated into shell scripts/commands is validated against shell metacharacters. ## Testing - [x] Added/updated automated tests - [ ] QA'd all new/changed functionality manually ## Database migrations - [x] Checked schema for all modified table for columns that will auto-update timestamps during migration. - [x] Confirmed that updating the timestamps is acceptable, and will not cause unwanted side effects. - [x] Ensured the correct collation is explicitly set for character columns (`COLLATE utf8mb4_unicode_ci`). <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added support for using Fleet variables (`$FLEET_VAR_HOST_*`) in Android configuration profiles, enabling per-host dynamic value substitution during deployment. * **Improvements** * Strengthened Android profile validation to reject unsupported Fleet variables and prevent invalid placements (for example, using variables in JSON object keys or non-string fields). * Enhanced deployment behavior when variables can’t be resolved for a host, marking affected profiles as delivery failed and avoiding partial policy application. * Improved Android per-host rollout by applying installs in staggered batches for smoother throughput. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
The MDM Android package attempts to decouple Android-specific service and datastore implementations from the core Fleet server code.
Any tightly coupled code that needs both the core Fleet server and the Android-specific features must live in the main server/fleet, server/service, and server/datastore packages. Typical example are MySQL queries. Any code that implements Android-specific functionality should live in the server/mdm/android package. For example, the common code from server/datastore package can call the android datastore methods as needed.
This decoupled approach attempts to achieve the following goals:
- Easier to understand and find Android-specific code.
- Easier to fix Android-specific bugs and add new features.
- Easier to maintain Android-specific feature branches.
- Faster Android-specific tests, including ability to run all tests in parallel.
