android - App remains in "most recent list" after killing it -

i'm killing app so:

android.os.process.killprocess(android.os.process.mypid());

but after it, app still appears in "most recent apps" list can reload it. mean it's still in memory? or list "snapshot" of app, actual process in fact died ?

if use :

android.os.process.killprocess(android.os.process.mypid());

then process killed active processes

but recent application window shows history of navigation capture application whether killed or not.

for example, have opened x app produces fatal exception, force close. x killed android system still visible in recent application window

i think not want exclude app recent application list window, not advisable because system apps launcher use thing , specify android:excludefromrecent flag in application
