Why Is Finish() Not Quitting Processing Immediately?

Is there any particular situation when it is handy to not quit the Activity immediately after calling finish() ? (in other way, why is this method not quitting the Activity immedia

Solution 1:

Shouldn't you do a return to prevent the codes below to execute:

if(somecondition){
    finish();
    return;
}

Solution 2:

Imagine you have a thread_0 with a loop handling all the events.

Calling finish adds a new event, but the activity isn't killed until thread_0 handles the event.

Solution 3:

Something to check: are you running any Async tasks that are not finished?

Solution 4:

finish() just hides the activity but not killed immediately. And makes it available for killing at later when os will need some memory to run other apps or processes.

Solution 5:

I guess Android allows you to save some data even after finish(). I think cancelling could also hurt the thread. In your case you could use return; to stop the code from executing.
