IntroductionLet's introduce a new Java framework-jna that accesses native code.The JNA (Java Native Access) framework is an open-source Java framework that is developed by Sun and is built on the basis of classic JNI.JNA Project Address: https://jna.dev.java.net/very powerful, easy to use, functionally similar to. Net of P/invoke.A terrible jni.We know that using JNI calls. dll/.so Sharing class libraries is very, very cumbersome and painful.If you have an existing. dll/.so file, if you use the
how to invoke a third party library file (. So) in the Android NDK1. Create a prebuilt subdirectory under the Project/jni directory (directory name customizable).2. Put the third party. So in the prebuilt and create the ANDROID.MK, as follows:Local_path: = $ (call My-dir)Include $ (clear_vars)Local_module: = xxxLocal_src_files: = libxxx.soInclude $ (prebuilt_shared_library)3. Add in Project/jni/android.mkLocal_shared_libraries: = xxx4. In the final pa
first, you need to install the Eclipse's CDT compilation environment. Configure the GCC compilation environment. LUnix usually have GCC, Windows needs to install a Cygwin.

2, create the project source file Share.cpp

[Static connection and dynamic link library]
[Static link]---> Static library: Link to the source program and load it to the virtual memory[Dynamic Link]---> Shared Library:For each database, the operating system allocates a specific virtual memory address.
Both static and dynamic libraries share code. Static link library (LIB ):Complete all assembly work before the program execution and generate an executable target file (exe file ). Static databases have two features:
The executable file generated after the Link contains the code of all functions to be called, so it occupies a large disk space.

One: Creation of a static library
The new one in vc++6.0 is the Win32 Static Library project, followed by two options. Choose it according to your needs.
The process of adding a specific class or function is like a standard project, creating a new class directly or adding a new. h (Example: MY.h) and. CPP (example: MY.cpp) files. Then write the implementation in it.
When finished, the comp

Beautiful Java chart class library and beautiful Java chart class librarySummary
When using java for background site development, charts and report functions are indispensable. This article recommends eight most brilliant and practical Java chart applications. Most of the chart applications have similar functions, mainly because of the aesthetics of the interface and the flexibility of use.Body 1. JFreeChart-multi-function Java chart class
The static library is connected to the target code when the program is compiled, and the static library is no longer needed when the program runs. After compiling the program file large, but loading fast, isolation.Dynamic libraries are not connected to the target code when the program is compiled, but are loaded only when the program is running, so a dynamic library

You can create your own package library by using the user library, where you can add frequently used jar packages or your own jar packages so that you only need to import the library when you use it.
No need to bother importing all the required jar packages every time
