Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 32140

50% of the time when running my app I’m getting this error

06-20 12:56:51.183: A/libc(32140): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 32140 (example.www)

I just have to reopen the app and then it works. But I don’t know why I’m getting this error and the app crashes.
I’m working with big images with dimensions, almost 1200x1200px and setting that as a background. I also use that image as a bitmap for some other activities as background. Also doing some calls to a server and getting JSON data back.
Hope I gave enough information, because I don’t know what to look for…
I’m developing for 4.1.2

    The real error is Out of memory on a 23818256-byte allocation. You are attempting to allocate a ~22MB block of memory, and you do not have that much free memory available, let alone a contiguous block that large.

    In this case, this is coming from a drawable resource. ~22MB would be a truly massive image, more like 2400×2400 than 1200×1200.

    Your process heap size is 48MB, which is substantial, but ~22MB is almost half your heap budget.

    I would recommend that you find out which drawable resource this is (looks like it might be a background of a RelativeLayout), then reduce its size and the sizes of similar images. Here, by “size” I mean total pixel count, not the on-disk size, as what matters is the decompressed size in RAM, not how big the image is on disk.

    Also, this might be an issue of resource directories. For example, if you put your 1200×1200 image in res/drawable/, that effectively is synonymous with res/drawable-mdpi/. If this device happens to be an -xhdpi device, then that would explain the memory usage, as Android will try to upsample this image and double each of the dimensions.
