Rithíonn Android ar raon an-leathan gléasanna agus leaganacha OS ("scoilteadh"), mar sin caithfidh feidhmchláir comhoiriúnacht leagain a bhainistiú — leaganacha níos sine a thacú agus gné níos nua a úsáid go sábháilte. Tá tuiscint ar leibhéal SDK, leabharlanna comhoiriúnachta, agus dírí truaillithe íochtar tábhachtach.
Leibhéal SDK: íos, sprioc, cum
minSdk → the OLDEST Android version the app supports (older devices can't install it)
→ lower minSdk = more devices reached, but more compatibility work
targetSdk → the version the app is TESTED/optimized against (and opts into its behaviors)
→ should be kept current (Play requires a recent targetSdk)
compileSdk → the SDK version used to COMPILE (access to newer APIs)
→ Balance: support enough old devices (minSdk) while targeting current behavior (targetSdk).
