Problem with Activity Finish

[Bill Norris]

I have a "Navigator" activity that contains several buttons that each start a different activity. Each of those other activities has a "back" button that goes back to "Navigator". On one particular activity, I'll call it Activity1, I have Activity.finish in the code of the Back button, as I want Activity1 to completely refresh upon the next re-entry. What I am finding is if I try to go immediately back to Activity1 from Navigator, Activity1 does not load. If I wait several (5-10) seconds, it will reload fine. If I remove the activity.finish, it will reload immediately. Also, if in debug I put a break at the line that calls Activity1, it loads immediately as desired when I hit F5 at the break. Is there something about activity.finish that I am not aware? Does it sometimes take several seconds to actually "unload"?

Hi Bill.

Can you post the code please?

Are you consuming the keypress event when you call Activity.Finish?

cheers, Ricky

Activity.Finish can take seconds, minutes, etc. The os makes the decision when to kill the Activity. If the resources are not pushed the os may not kill it for some time. I have devices that a hour later the Activity is still alive.

RE

Is it accurate to conclude that once activity.finish is called, then that activity will not re-load until activity.finish is, well, finished?

I think that this issue is actually related to a different cause. In some cases when you switch back and forth between activities the intent may be ignored. The solution is to use a short timer to start the activity.
