cocos2d-x 3.0rc2中讀取sqlite文件

cocos2d-x 3.0rc2中讀取sqlite文件的方式，在Android中直接讀取軟件內的會失敗。需要複製到可寫的路徑下

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("數據庫路徑：%s", path.c_str());
int resultOK = sqlite3_open(path.c_str(), &dbFile);

if (resultOK != SQLITE_OK) {
    sqlite3_close(dbFile);
    CCLOG("數據庫打開失敗: %d", resultOK);
    return;
}
