Besides using microservices, what other ways can tasks be executed in the background?

In addition to microservices, the following methods can be used to perform background tasks on Android:

• WorkManager — the recommended API for deferred and periodic tasks that are guaranteed to be executed, even if the app is closed or the device is rebooted.

• IntentService — a service that performs tasks on a separate thread and automatically stops after completing its work. Suitable for short background operations.

• Foreground Service — a service that runs in the background with a user notification, used for tasks requiring constant execution (e.g., music, navigation).

• HandlerThread and ThreadPoolExecutor — for managing threads and executing tasks in the background within the app.

• AlarmManager — for scheduling tasks at specific times, can be used together with BroadcastReceiver.

The choice depends on the requirements for execution time, guarantee of start, and battery impact.
