Deleting stacks on the fly

@ Jacque: I don't think it is ram after all.
FYI: on my Nexus 5 I have 1.8 GB RAM and our new app + All of Googles "widgets" that come preloaded take up a mere .8 GB and I have a full GB of RAM free. after proceeding (as we discussed off list with our team) to delete stacks when we move from one to another, so that only 1 or 2 are ever open in memory… I am pretty certain I'm not have a memory issue on this Android Device: but it still crashes.
I took this to HQ… I guess you all know about plugging in your android phone and running ./adb logcat and then pass that over to LC support.
If you are interested you can view it here:
http://wiki.hindu.org/uploads/siva-siva-app_adb-log.txt # 13MB file
if you search
Activity Manager: Process com.himalayan
You will run into all the instances of
ActivityManager: Process com.himalayanacademy.sivasiva (pid 25473) has died
There appear to be three different "flavors" of "exited due to signal (11) in that log. I won't detail them here as I don't grok the log well enough to talk about it.
Hopefully HQ will figure it out… building from 8.1.3 (RC2)
does 9 dp4 change the file format? Safe? I could make back ups of course. and test… but need to keep moving on content dev…
I have no recipe or rather, we do, but it seems harmless.
we "Go" from one stack to another, then after 10 milliseconds, delete the first one
here is the handler where the app exits on signal 11, you can see where we were fiddling with
1) just closing it,
2) opening stack B and deleting stack A
3) Opening stack B and send a "Delete" stack A in 10 milliseconds.
All three scenarios cause android to crash and we have *lots* of open RAM.
command portal_GoStack stackName
-- goes to the new stack
-- closes the current stack
-- safely ignores if we are alrady in the new stack
put the short name of this stack into oStackName
if oStackName = stackName then return oStackName
go to stack stackName
--close stack oStackName
-- test deleting the stacks to save on RAM
send "portal_RemoveStack oStackName" to me in 10 milliseconds
-- delete stack oStackName
command portal_RemoveStack stackName
if stackName <> "Siva-Siva-App" then
delete stack stackName
# Works perfectly well on iOS

I frequently delete stacks when memory is an issue, which is the problem
with Swami's stack suite. I also create almost all new stacks with
destroystack set to true for the same reason.
