My other project is crashing on Android the same way. It also has heavy 
server/internet use. I'm starting to think that's where the problem lies.

Re: Deleting stacks on the fly

[Sannyasin Brahmanathaswami via use-livecode]

FWIW, tested on an android device with plenty of memory

Deleting stacks isn't helping. My Nexus 5 has 1 GB free RAM even with all of 
Google's widgets and my app open and going from Stack B back to stack A then 
deleting StackcB in 10 milliseconds  is "nothing" in terms of memory 
requirement, but crashes in Android every time… 

I have a report in to HQ…

use-livecode"  wrote:

I'm trying to optimize for minimal RAM usage on mobile. The app is modular 
with many stacks that are opened from the mainstack.

I had this before in a global library:

command portal_GoStack stackName
-- goes to the new stack
-- closes the current stack # But we want to delete it to clear RAM
-- 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
delete stack oStackName
return oStackName
end portal_GoStack

This is called from a button on a navigation bar of the stack we want to 
close and delete, as it opens a different stack.

This works if we just use "close stack oStackName"

but if I change this to "delete stack oStackName"

we get an error: stack "lib_SivaSivaPortal": execution error at line n/a 
(Object: stack locked, or object's script is executing) near "widget 
"go-home-portal" of group "homeScreensBottomNav" of card "images-quotes" of 
stack 
"/Users/Brahmanathaswami/Documents/_Siva-Siva-App/modules/gems/gems.livecode""

Obviously this means that the stack "gem.livecode" which has the button 
which is trying to "navigate" back to the home/main stack, cannot be deleted 
because the button script that calls the library handler is considered to be 
executing.

Closing it first before deleting does not help.

so I tried using "send in 10 milliseconds"  And this *does* work.. I'm just 
trying to see if this is best practice. both stacks will occupy RAM briefly, 
but  there is no other way that I know of to avoid this without a "flash" of 
some empty screen.

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
send "removeStack oStackName" to me in 10 milliseconds
return oStackName
end portal_GoStack

command removeStack stackName
delete stack stackName
end removeStack


Stack A opens
Stack B opens on top
Stack B want to close itself, be deleted (removed from memory) and open 
stack A

Anyone has gone through this loop already and discovered best practices to 
accomplish this?

Re: automating enabling of plugin settings on new versions

[panagiotis merakos via use-livecode]

Hi Richard,

I think that changing the permissions of the app bundle may cause issues
with OSX's Gatekeeper. If you want to customize or change the settings (and
make sure the changes do stick) of the Application Browser, I suggest you
put a copy of it in your Plugins folder.

In case you are interested, see
http://quality.livecode.com/show_bug.cgi?id=17757 for more details on this.

Best,
Panos
