Java Native Interface(JNI) allows Java applications to call native methods, which are special methods written in native programming languages such as C or C++. Historical usages of native methods Access to platform-specific facilities such as registries and file locks. Access to libraries of legacy ...
For example, given these native methods in Java: package p.q.r; class A { native double f(int i, String s); native double f(int i, Object s); } The corresponding C functions must be named Java_p_q_r_A_f__ILjava_lang_String_2 and Java_p_q_r_A_f__ILjava_lang_Object_2,...

intmain(intargc,char**argv){JavaVM*vm;JNIEnv*env;startJVM(&vm,&env);registerNatives(env);executeJNIAdder(env);vm->DestroyJavaVM();return0;} 从上面的例子中可以看出: RegisterNatives可以用来注册一个类文件中所有 native methods 的实现。 这个方法有三个 argument:...
()to attach itself to the VM and obtain a JNI interface pointer. Once attached to the VM, a native thread works just like an ordinary Java thread running inside a native method, with the one exception that there is no Java caller when callingcaller-sensitive methods. The native thread ...

说实话,Native Modules 全量绑定在现有的架构里是无解的:不管这个 Native Methods 你有没有用到,容器启动时先全部初始化一遍。在新的 RN 架构里,TurboModules 会解决这个问题(本文下一小节会介绍)。 如果非要说优化,其实还有个思路,你不是全量初始化吗,那我让 Native Modules 的数量减少不就行了?新架构里有一...
