OutofMemoryError While Unzipping Compressed Textures
« on: January 16, 2015, 10:33:17 am »
I load four images. Images have 2048*1024 resolution. I compress textures for avoid outofmemoryerror but while unzipping textures I get outofmemory error. This error doesn't always happen. Here is my code and log.

MyRenderer.java

That's simple: You run out of memory. Keep in mind that a 2048*1024 texture requires 8MB for each image in main memory, 8MB on the gpu and up to 8mb (depending on the compression rate) for the zipped data. Plus mipmaps and additional stuff that your app requires. Keep in mind that you are on a mobile device and that, all progress aside, this is still an environment with limited resources.
The amount of memory available to the VM depends on the Android version and some vendor settings. In your case, it seems to be 64mb, which indicates that this is a rather old device/Android version. You can try to set the largeHeap setting in your manifest (http://developer.android.com/guide/topics/manifest/application-element.html), but that doesn't always help. It's better to watch your content. Do you REALLY need 4 textures of that enormous size?

Thanks Egon. largeheap=true works.

Just keep in mind that it's up to the vendor what this switch actually does. They are free to ignore it (albeit i've never come across this...).

Hello , I meet this case too, If  add more texture , the memory sieze > 32 M ,the OOM is occurs. I am wonder  If  use native method to decode the picture and  let  bitmap reference  to native memory, maybe can resove  OOM, but I don't know this way can do this or not .

Personally, i haven't seen a device/VM with just 32mb since Android 1.6. Current devices provide 256 or 512 without any problems. Native memory will be counted as memory of the process too. That's why the native memory in which the textures reside when you move them onto the gpu counts as well.
If your app throws an OOM, you are simply using too much memory. Try to lower that and also define a minimum amount of memory that your app should be able to work with and develop with that barrier in mind. IMHO, something like a 2048*1024 texture shouldn't be used on a mobile device except for some very special cases. Apart from that, here are some hints regarding memory usage and reduction: http://www.jpct.net/wiki/index.php/Reducing_memory_usage

As an example: My RPG ( https://www.youtube.com/watch?v=bJf2B3tlg5Y ) uses one 512*512 texture. All other textures are smaller. It uses one 1000*1000 heightmap, 18 different animated meshes for NPCs and enemies, dozens of other meshes, 64 sounds and 3 songs and it all fits into 64mb of memory by using some of the hints mentioned on that wiki page.
