HarmonyOS 是否有C++ native层读取音频文件并在上层进行播放的例子

ArkTS调用native方法再回调参考示例：

uint8_t *ReadArraybuffer() {
    uint8_t *buffer = new uint8_t[1024];
    memset(buffer, 2, 1024);
    return buffer;
}
void ToFin(napi_env env, void *finalize_data, void *finalize_hint) { free(finalize_hint); }
static napi_value GetArraybuffer(napi_env env, napi_callback_info info) {
    uint8_t *buffer = ReadArraybuffer();
    napi_value result;
    napi_status status;
    status = napi_create_external_arraybuffer(env, buffer, 1024, ToFin, buffer, &result);
    if (status != napi_ok) {
        napi_throw_error(env, nullptr, "Failed to create external ArrayBuffer");
        delete[] buffer;
        return nullptr;
    }
    return result;
}
