how to use sprite from CCFileUtils::get Writable Path() path in Andoid??

I have a sprite on this path CCFileUtils::getWriteablePath()
I try this to achieve this sprite but it give error like this—>get data from file(assets/theme.png) failed. Why it find in assets folder???

string filePath = CCFileUtils::getWriteablePath();
filePath += fileName; //fileName theme.png
CCSprite* themeImage = CCSprite::spriteWithFile(filePath);

Thanks in Advance

I will check it.
You can check the path return by CCFileUtils::getWriteablePath(), it will start by “/”.
And engine will read data from the path if the path is a absolute path.
