cocos2d-x 3.0rc2中读取sqlite文件的方式，在Android中直接读取软件内的会失败。须要复制到可写的路径下

sqlite3* dbFile = NULL;std::string path;    path = FileUtils::getInstance()->fullPathForFilename("db1.db");    #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);    #endifCCLOG("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;}
