JNI是Java Native Interface的缩写(Java本地调用),Java程序中的函数可以调用Native语言写的函数(一般指的是C/C++编写的函数),Native语言写的函数可以调用Java层的函数。 二、为什么要有JNI Java语言的跨平台是因为在不同平台上可以运行Java虚拟机,而虚拟机是跑在具体平台上的,而本质上Java是通过JNI技术实现的跨平台...
JNI does very little error checking. Errors usually result in a crash. Android also offers a mode called CheckJNI, where the JavaVM and JNIEnv function table pointers are switched to tables of functions that perform an extended series of checks before calling the standard implementation. JNI很少...
