如何使用JNI将数据从原生c二进制文件传递到android模型？

public class NativeUtils {
    public native void loadModel(String filePath);
    public native void processData(byte[] data);
}

javah -jni NativeUtils

#include <jni.h>
#include "NativeUtils.h"

JNIEXPORT void JNICALL Java_NativeUtils_loadModel(JNIEnv *env, jobject obj, jstring filePath) {
    const char *file = (*env)->GetStringUTFChars(env, filePath, 0);
    // 读取原生C二进制文件的代码
    // 将数据传递给Android模型的代码
    (*env)->ReleaseStringUTFChars(env, filePath, file);
}

JNIEXPORT void JNICALL Java_NativeUtils_processData(JNIEnv *env, jobject obj, jbyteArray data) {
    jbyte *dataArray = (*env)->GetByteArrayElements(env, data, 0);
    jsize dataSize = (*env)->GetArrayLength(env, data);
    // 处理数据的代码
    (*env)->ReleaseByteArrayElements(env, data, dataArray, 0);
}

public class MainActivity extends AppCompatActivity {
    static {
        System.loadLibrary("nativeutils");
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        NativeUtils nativeUtils = new NativeUtils();
        nativeUtils.loadModel("path/to/model.bin");

        byte[] data = // 从原生C二进制文件中读取的数据
        nativeUtils.processData(data);
    }
}
