Cocos Creator能否调用原生C/C++库？Android.so式调用方案咨询

Great question! The short answer is yes, Cocos Creator fully supports integrating precompiled native C/C++ libraries—and it works in a way that’s very similar to how Android uses .so files, which is perfect for your scenario where you can’t share source code, only binaries.

Here’s a breakdown of how to implement this across major platforms:

Since you’re familiar with .so files, this will feel straightforward:

• Place your precompiled .so files (targeting the correct architectures: armv7a, arm64-v8a, etc.) in your Cocos Creator project’s native/engine/android/app/src/main/jniLibs/[architecture-folder] directory.
• You’ll need a simple JNI bridge (written in C++) to expose your C library’s functions to the JavaScript layer. For example:

// jni_bridge.cpp
#include <jni.h>
#include "your_c_library.h" // You must provide the header file for your C library

extern "C" JNIEXPORT jint JNICALL
Java_com_your_project_package_NativeBridge_callCLibraryFunction(JNIEnv* env, jobject thiz, jint input) {
    // Call the function from your C library
    return your_c_library_function(input);
}

• In your JavaScript code, use Cocos’s built-in reflection API to call the JNI method:

const result = jsb.reflection.callStaticMethod(
    "com/your/project/package/NativeBridge",
    "callCLibraryFunction",
    "(I)I",
    42
);

For iOS, you’ll use precompiled .a static libraries or .framework bundles:

• Drop your compiled binary files into the native/engine/ios/ directory of your project.
• Create an Objective-C++ bridge file (with a .mm extension) to wrap your C library functions:

// NativeBridge.mm
#include "your_c_library.h"

@implementation NativeBridge
+ (NSInteger)callCLibraryFunction:(NSInteger)input {
    return your_c_library_function((int)input);
}
@end

• Call the wrapped method from JavaScript using the same reflection API:

const result = jsb.reflection.callStaticMethod(
    "NativeBridge",
    "callCLibraryFunction:",
    42
);

• Windows: Use precompiled .dll files. Place them in the native/engine/windows/ directory, then use C++ to load the library dynamically (via LoadLibrary) or write a static binding to expose functions to JS.
• macOS: Use .dylib dynamic libraries or .framework bundles. Place them in native/engine/macos/, then use dlopen to load the library and access its functions, or create a C++ binding layer.

• Header Files Are Required: Even though you can’t share source code, you must provide the header files for your C library. The bridge code needs these to know the function signatures and data types.
• Architecture Alignment: Make sure your compiled binaries match the target platform’s architecture (e.g., arm64 for modern iOS/Android devices, x86_64 for Windows/macOS desktops).
• Symbol Conflict Prevention: Use compiler flags like -fvisibility=hidden when building your C library to avoid global symbol conflicts with the Cocos Creator engine.
