ConstantsA constant is defined with the Const keyword in c/s + +, whereas in Java Const is not a key character, but rather a reserved character, which uses the final keyword to define a constant with the following syntax:Final DataType Constantname;Where final is the keyword that defines the constant, datatype is the data type that indicates the constant, and
ArticleDirectory The simplest steps for Java to call C/C ++ code JNI (Java Native Interface) Java is a cross-platform language, but sometimes it still needs to be called locallyCode(These codes are usually written by C
Original article: Java calls C (implementing Java local methods in Linux) 1.

C Language: code compiled to get machine code, machine code on the computer directly running, each instruction directly control CPU work. Other languages: Code compiles the bytecode, and the virtual machine executes the bytecode and converts it to machine code to run on the processor. Python's syntax is concise, the class library is rich, and if you implement the same functionality, Python may need 10 lines of code, and
, generates assembly code (. s), which is basically the basis of all modern unstructured languages. Then, the assembler translates the assembly code into the target code (. O and. OBJ files, machine commands ). Finally, the linker links all target files related to each other and the generated executable files or libraries. In general, our code is first translated into assembly code, and then into machine commands (Binary Code ). What is a macro? In C
Many people should be impressed with the JNI (NDK), the Android NDK has a relatively good chance of exposure, this example on the Android platform, for example, the PC side of the simple windows as an example, the code finished with VS or gcc compiled into DLL files, Thrown into the system system32, is the environment variable configuration folder under, Linux may also be similar to this meaning, the rest of the code is like Android, to load the dynamic link library.Here do not repeat, directly

There are usually two ways to develop Android applications: ndk and eclipse, or add them directly in the android SDK. This section describes how to add an application in the android SDK environment. It involves JNI and Java calls to JNI. The JNI code file is C ++. The first step is to establish the JNI-Layer Code. Note that the JNI code path has a great relationship with the
