更改 android 文件存放目录 getWritablePath() 为sdCard

CCFileUtils::sharedFileUtils()->getWritablePath() 默认为 /data/data/prjName/

"Java_org_cocos2dx_lib_Cocos2dxHelper.h"  的 std::string getFileDirectoryJNI() 方法

通过 jni 调用  org.cocos2dx.lib.Cocos2dxHelper.getCocos2dxWritablePath() 获取

具体"路径str" 在org.cocos2dx.lib.Cocos2dxHelper.init() 中

edit line：70 

 Cocos2dxHelper.sFileDirectory = pContext.getFilesDir().getAbsolutePath();//设置

/**方法用于获取SDCard的状态，如果手机装有SDCard，并且可以进行读写，那么方法返回的状态等于Environment.MEDIA_MOUNTED **/
if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))
{
    Cocos2dxHelper.sFileDirectory = Environment.getExternalStorageDirectory()+"/"+applicationInfo.packageName;
}

"Java_org_cocos2dx_lib_Cocos2dxHelper.h" 在 cocos2dx\platform\android\jni

class "Cocos2dxHelper" 在 cocos2dx\platform\android\java\src
