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);

#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;

}
