[android-developers] Re: How to get System Endianess
Thanks, but I think it is the java virtual machine byte order. I am communicating to/from low level stuff (kernel driver).

[android-developers] Re: How to get System Endianess
well, assuming you code in C: int n = 1; char *p = (char*)n; int little_endian = *p == 1; does that help?

If it's C you don't even need to booleanize it:
int isLittleEndian(void)
{
/*static*/ short order = 0x0001;
return *((char*) order);
}
At any rate, the original poster was using System.getProperty before,
so I'm assume this is for code written in the Java programming
language. ByteOrder.nativeOrder() is defined as: Retrieves the
native byte order of the underlying platform. There's no virtual
machine byte order.
In android you can see that dalvik/libcore/nio/src/main/java/java/nio/
ByteOrder.java has a NATIVE_ORDER define that comes from
Platform.getMemorySystem().isLittleEndian(), which does something
similar to the above.
