B4J Question outofmemoryerror java heap space, what to look for?

[kostefar]

Dear All,

I have an app running in debug mode which after 7ish hours crash with this error. I see it happening when a timer event that runs every 2 mins is triggered, where a bunch of maps and lists are being initialized and cleared. They dont grow very big and there arent alot of them; I´ve had projects running with no issues that grew much larger maps and lists. I thought that maybe initializing a map or list over and over again, being unncessary to do as well when it also gets cleared, somehow could be the reason so now I´m only clearing them and waiting to see if it crashes again.
But am I right that this could be a reason why java heap space grows, or are there other things that I should consider?

Thanks in advance!

try adding this to your manifest editor

SetApplicationAttribute(android:largeHeap,"true")

Thanks, but that´s a b4a solution.

Btw, I do have these set:

#VirtualMachineArgs: -Xms1024m -Xmx1024m

i would make the timer faster and think the problem will happen direct.

You should never test performance or memory issues in debug mode.

Ok, thanks. So after all this could be something that won´t happen in release mode?

Yes.

It might be a real issue, however you cannot say it until testing in release mode.

Ok, good to know. I´ll run it in release mode to see if I get any errors!

Update: I´ve had the app running for 18 hours in release mode with no memory errors - that´s it!
