Android apps کو اکثر background کا کام کرنے کی ضرورت ہوتی ہے — ایسے tasks جو فوری UI کے باہر چلتے ہیں، جیسے ڈیٹا synchronizing، uploads، یا periodic jobs۔ Android کئی mechanisms فراہم کرتا ہے (WorkManager، Services، coroutines) مختلف use cases کے ساتھ، اور OS سے اہم constraints کے ساتھ۔
Background work کی options
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SERVICES → general background components (largely superseded by WorkManager/coroutines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)
