What methods do you use to update local data on a device and synchronize it with the server?

To update local data on the device and synchronize it with the server, the following methods are usually used:

1. Local caching and database — data is stored in SQLite, Room, or SharedPreferences for quick access.
2. API synchronization — when connected to the network, the app sends changes to the server and receives updates.
3. Using the Repository pattern — abstracts the data source and manages synchronization.
4. Working with queues and deferred tasks — for example, through WorkManager for reliable background synchronization.
5. Conflict resolution — applying merge or priority strategies when data discrepancies occur.

Example using WorkManager for synchronization:

val syncWork = OneTimeWorkRequestBuilder<SyncWorker>().build()
WorkManager.getInstance(context).enqueue(syncWork)

Thus, data is first updated locally, then asynchronously synchronized with the server, ensuring relevance and resilience to network errors.
