更改 android 檔案存放目錄 getWritablePath() 為sdCard

標籤：android   c   style   class   blog   code   

CCFileUtils::sharedFileUtils()->getWritablePath() 預設為 /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() 擷取

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

edit line：70 

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

/**方法用於擷取SDCard的狀態，如果手機裝有SDCard，並且可以進行讀寫，那麼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;}

 

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

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