Android Bitmap - What is nativeBitmap?
In the Android frameworks, a long member called native anything is usually a platform pointer (a C/C++ pointer) stored in an integer. The bitmap object is allocated in native (C/C++) code, and the pointer to that object is stored on the Java object as a long. They use a long...

Append String to native Java array

Golang custom sort is faster than native sort
The difference seems to largely be due to the fact that your Quicksort uses builtins. It slices and uses len. Keep in mind that sort.Sort takes in a sort.Interface. So every time you call len it calls slice.Len and every time you do array[i],array[j] = array[j],array[i] it has to call...

How to add an exe path to the windows registry, to get executed on the native mode?
I believe you're thinking of the BootExecute value, located in this key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager This is a REG_MULTI_SZ value, i.e., it contains multiple strings. Each string contains an arbitrary identifier, the name of the executable to run, and the arguments to pass to the executable. For example, the default setting...
Gradle C/Native Plugin: Directory Structure, Platforms and Flavors
The convention for native binaries in Gradle is to put headers in src/{componentName}/headers and C source files in src/{componentName}/c, where componentName would be whatever you name the component (given the question, I'm guessing that would be helloworld, but it depends on how you declare it). Flavors are for different variants...

Why is Object.clone() native in Java?

Why doesn't java's -verbose:class argument include jre inherent native classes?

Basically, one cannot distinguish the loading of such a class as a separate event; they are loaded in bulk from a pre-cached image.
