Android programos dažnai turi atlikti foninį darbą — užduotis, kurios vykdomos ne iš karto UI, pavyzdžiui, duomenų sinchronizavimą, išsiuntimus ar periodinius darbus. Android suteikia kelis mechanizmus (WorkManager, Services, coroutines) su skirtingais naudojimo atvejais, be to, yra svarbų OS apribojimai.
Fonio darbo parinktys
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SERVICES → general background components (largely superseded by WorkManager/coroutines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)
