[Q] VM Heap Size?

---

Can someone with a device please tell me the VM Heap Size?

This can be found in /system/build.prop for those who don't know.

Thanks.

Bump ... anyone that can answer me please?

How can I find the info?

If you have root explorer it can be found in the build.prop file in your system dir, otherwise you can install the free VM Heap Tool from the market and that should tell you what it currently is.

I'm hoping to get these books optimised for the XOOM and need to know how much VM Heap I have to play with (also, I just did the button fix you mentioned, shifted them up top the middle ).

Thanks man.

dalvik.vm.heapstartsize=5m
dalvik.vm.heapgrowthlimit=48m
dalvik.vm.heapsize=256m

Holy crap, thanks, that's a rather large heap size.

The first two seem to be new though, I have never come across them. I wonder what the second one means though, if that's the maximum growth in a single "grow", it wouldn't make sense for it to be 5 + 48 cause that's nowhere near the 256 that's defined.

I'll have to look into it, thanks for the information tough.

Guess you beat me to it

Now I think about it, I did find through testing that the VM Heap is allowed to grow over the stated size, what this says is that it can grow by uptown 48M over the 256M size.

As a user it's pretty unimportant but from a development perspective that gives a lot of headroom for maintaining stuff in memory.

As a comparison the base VM Heap size for android phones is 16M with faster / later devices being allowed 24 or 32, as high as 48 on the pre-honeycomb tablets.

This is a major increase which hopefully, from a consumer perspective means richer more capable applications.

Happy days.

Kinda reminds me of the eclipse.ini file for Eclipse IDE

--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Xms64m
-Xmx1024m
-XX:MaxPermSize=512m

Thats what I have for best performance while developing in Eclipse.

I think growth limit is the increment by which the heap can can grow by. Start size is, well the heap start size.

heapsize=256, now that confuses me. Is that the upper bound on the heap?
There was no other reference to maxsize or the like.
