综述一下JNI的原理 1.通过System.loadLibrary()或System.load()加载动态库 System.load("/data/local/tmp/libgityuan_jni.so...；而System.loadLibrary(String libname)则只会从指定lib目录下查找，并加上lib前缀和.so后缀； 自动加载库的依赖库的不同：System.load(String filename...)不会自动加载依赖库；而System.loadLibrary(String libname)会自动加载依赖库。...JNI原理分析 文件MediaPlayer.java中调用System.loadLibrary(“media_jni”)，把libmedia_jni.so动态库加载到内存。...总之，System.loadLibrary()的作用就是调用相应库中的JNI_OnLoad()方法。接下来说说JNI_OnLoad()过程。

这些native方法由外部的本地库（如C/C++编写的动态链接库）实现，JVM需要通过System.loadLibrary()或System.load()方法来加载这些库。...public class NativeExample { static { System.loadLibrary("exampleLib"); } public...NativeExample(); example.nativeMethod(); // 这里将抛出UnsatisfiedLinkError } } 错误分析： 在静态代码块中，System.loadLibrary...以下是一个正确的代码示例： public class NativeExample { static { try { // 正确加载存在的库 System.loadLibrary...确保System.loadLibrary("exampleLib");加载的库在系统的java.library.path中存在，并且库文件完整且与系统兼容。
