Hi Mark, thanks for your reply. Yes, it's probably managed by the system, yet I'm still wondering:
Below you can see that the browser activity runs in different processes (#2307, #5536) before and after I killed/restarted it, and yet it's displaying / restoring the same UI input values entered by the user, regardless of being in an entire new process. So, are the two activities in these two processes actually the same instance? If so, why? (I was thinking of something like 'task parenting' to be eventually happening here, but it cannot be, since there's no android:allowTaskReparenting attribute in the application's manifest and the default value for an activity for such is false. And it would also mean that the activity wouldn't really be gone even after kill has been executed.) [*** some user input on UI in the browser app ***] # ps | grep -i browser ps | grep -i browser app_27 2307 75 131944 25960 ffffffff afe0da04 S com.android.browser # killall -9 com.android.browser killall -9 com.android.browser [*** browser is killed, then I press home long, select browser app from recent apps ***] # ps | grep -i browser ps | grep -i browser app_27 5536 75 121868 24316 ffffffff afe0da04 S com.android.browser [*** ... and the UI still shows values from the activity in the previous #2307 process *** ] On Nov 8, 8:19 pm, Mark Murphy <mmur...@commonsware.com> wrote: > On Mon, Nov 8, 2010 at 1:37 AM, Mathias Lin <m...@mathiaslin.com> wrote: > > That's what I thought.
