Cocos2dx Android：getFileData无法从资产获取.json文件

Question

我正在为Android和IOS开发跨平台应用程序。 当我尝试获取位于Assets文件夹中的.json文件时，如下所示

const char * genrefile =   CCFileUtils::sharedFileUtils()->fullPathFromRelativePath("genres.json");
CCLog( " %s ---------- genrefile ---------", genrefile);

size_t size;
unsigned char * charbuffer = CCFileUtils::sharedFileUtils()->getFileData(genrefile, "rb", 0);

控件通过以下堆栈跟踪从应用程序中退出

getFileData(...)的方法CCFileUtils类工作正常获取的图像，但不与其他文件。 非常感谢您的帮助。

Answer 1

尝试这个：

unsigned long bufferSize = 0;
unsigned char * charbuffer = CCFileUtils::sharedFileUtils()->getFileData(genrefile, "rb", &bufferSize );
