Android aplikacije pogosto potrebujejo delo v ozadju — naloge, ki se izvršavajo zunaj neposrednega uporabniškega vmesnika, kot so sinhronizacija podatkov, nalaganja ali periodične naloge. Android ponuja več mehanizmov (WorkManager, Services, coroutines) z različnimi primeri uporabe, plus pomembne omejitve operacijskega sistema.
Možnosti za delo v ozadju
COROUTINES (in a ViewModel scope) → for async work tied to the UI/screen (network calls,
loading data) — runs while the screen is active
WORKMANAGER → for DEFERRABLE, GUARANTEED background work that must complete (even if the
app closes or the device reboots): syncing, uploads, periodic tasks, retries
→ the RECOMMENDED solution for most persistent background work
FOREGROUND SERVICE → for ongoing, user-visible background work (music playback, navigation,
active tracking) — shows a persistent notification
SERVICES → general background components (largely superseded by WorkManager/coroutines
for most cases)
