更改 android 文件存放目錄 getWritablePath() 為sdCard

CCFileUtils::sharedFileUtils()->getWritablePath() 默認為 /data/data/prjName/

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

通過 jni 調用  org.cocos2dx.lib.Cocos2dxHelper.getCocos2dxWritablePath() 獲取

具體"路徑str" 在org.cocos2dx.lib.Cocos2dxHelper.init() 中

edit line：70 

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

/**方法用於獲取SDCard的狀態，如果手機裝有SDCard，並且可以進行讀寫，那么方法返回的狀態等於Environment.MEDIA_MOUNTED **/
if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))
{
    Cocos2dxHelper.sFileDirectory = Environment.getExternalStorageDirectory()+"/"+applicationInfo.packageName;
}
