Android Question System Out of Memory

System.OutOfMemoryException is a .NET Framework error. If your app is really that large it might just be that the IDE is running out of memory. I assume you have a 64bit OS but B4A is a 32bit program so can only use up to 4GB of memory so I can possibly see it running out of memory when compiling but it's a bit odd that it happens when editing. I know Erel is considering switching the B4X IDEs to 64bits but I don't know if he has a timescale for doing it - but that is no help to you.

Have you another machine you can try it on to see if that suffers the same problem with that app?

Yes, I have a collegue with the exact same problem. His laptop as also 16GB.
It never occurred to me that the B4A could be a 32Bits program. That explains it. I can only hope Erel doesn't take too long to switch the IDE to 64Bits.

In the meantime you could try compiling some of your more stable classes to libraries which might ease the problem a bit.

I experienced compilation timed out issue and the IDE “eat up” a lot of resources (CPU and RAM) before. My brother accidentally shutdown my windows while my IDE is opened. This has caused corrupted files. After I reinstall the IDE, everything has backed to normal.

It is not the issue that I am experiencing, however. But thanks for the input.

I have the same problem, 16BG RAM computer and a huge project. Actually, when I compile my progect and I get "system out of memory", my RAM is not fully used. Everytime I do changes on my code ad I compile, I have to close and re-open the project before I can compile again. I considered to create a library of some modules, but I have to edit them often (surely I'll have to compile them in the future). If switching the B4X IDEs to 64bits solves this, I look forward the update

Kind regards

Hello, I suffer from exactly the same problems you have described. Also waiting for the 64 Bits version.

Would you check if one of these applies.

Its been 3 days with some stability, my laptop has 8GB ram, then I was curious. So i found the ini file and set

MaxRamForDex=5120

and in all my b4j apps I have added, #VirtualMachineArgs: -Xms2G -Xmx2G

and instead of out of memory errors every now and again, they seldom happen, especially when I open the abstract designer. I also noted that when I dont use File > Recent files to open a new project, closing B4J and then opening it helps. Yes ram usage jumps to 1G on the task manager within 5 seconds of opening my library.

From time to time I close and restard the IDE as the keyboard lag in the IDE just becomes a headache. Why the out of memory errors have decreased? I dont know. They happen, but not as often as before, maybe its this or something else, I dont know.

I found out I can't open 2 B4A projects at the same time or else the memory usage will shoot up high.
