Memory allocation

Re: Memory allocation

How many images are you using? I am wondering how you are even able to do this. When I try to load more than 3 medium size .png files (like 500 X 700) I crash with the OPEN GL mem error. I can't even run processing at all on my honeycomb emulator cause I get the same out of memory error.

Did you have to increase memory allocation?

20 pngs (300 X 300)
28 pngs (100 X 100)
and a few other

the emulator doen't work for me either with such images. I'm directly using the debug mode with my HTC Desire HD via USB.
This phone has 768 mb of ram. At about 150-200 mb are free when no app is running.

I've made some more tests:
I removed every image from the sketch (in the data folder and in the code).
Debug monitor says it takes 6mb of heap.
Task manager apps on the phone: up to 38 mb of memory! (tested it with different managers)

And now: I changed the renderer to P2D instead of P3D:

only 7mb of memory (according to task manager)

30mb less (without images).

Thanks for testing! This information will be useful to debug image and texture functionality in P3D.

@andres any news?

I just found some crash reports from users on my android market developer account.

the heap sizes etc. could be interesting
maybe it's useful, andres

Re: Memory allocation

Do you do any garbage collection at all?

I'm not sure how Android handles this - similar to traditional Java or not... since it's really C++ with a JVM on top...

I'm also curious if there is any difference if your readling/loading/saving to SD Card rather than a data/assets directory within the application folder...

Re: Memory allocation

Garbage collection should free up memory automatically.

Maybe I should try to call System.gc().
However, from android documentation:

System.gc(): Indicates to the VM that it would be a good time to run the garbage collector. Note that this is a hint only. There is no guarantee that the garbage collector will actually be run.

Yeah I don't use the SD card (haven't added the permission). I don't know if there's a difference.

I just found an interesting pdf here.
