android - Service closes when I clear app History by Long Pressing Home key -

i launching service activity. service runs countdown timer launch ads.

but when clears apps history long pressing home key forcefulness stop app @ line checking intent extras.

it gives null pointer exception @ line below,

public int onstartcommand(intent intent, int flags, int startid) { if (intent.getextras() != null && intent.hasextra("type")) // <== npe @ line type = intent.getextras().getstring("type"); . . . }

as can see tried check if intent null intent.getextras() != null still gives npe , forcefulness closes app.

why onstartcommand called when clear history , countdown timer finishes , launch other activity, launches service afterwards.

logcat :
