3.x的sqlite在Android读写失败

问题描述如题，解决方法：直接在软件内读取会失败，需要复制到可写路径内

  sqlite3* dbFile = NULL;

  std::string path;

  path = FileUtils::getInstance()->fullPathForFilename("db1.db");
    
  //安卓平台
  #if CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID
      path  = FileUtils::getInstance()->getWritablePath();
      path  += "/db1.db";

      FILE* file = fopen(path.c_str(), "r");
      if (file == nullptr)
      {
          ssize_t size;
          const char* data = (char*) FileUtils::getInstance()->getFileData("db1.db", "rb", &size);
          file = fopen(path.c_str(), "wb");
          fwrite(data, size, 1, file);
          CC_SAFE_DELETE_ARRAY(data);
      }
      fclose(file);

  #endif

  CCLOG("数据库路径：%s", path.c_str());
  int resultOK = sqlite3_open(path.c_str(), &dbFile);

  if (resultOK != SQLITE_OK) {
      sqlite3_close(dbFile);
      CCLOG("数据库打开失败: %d", resultOK);
      return;
  }
