android 退出应用重进聊天会话和记录会出BUG，很重要，新回复

W/System.err﹕ org.json.JSONException: Unterminated object at character 203 of {"from":"96","to":"87699388775793068","bodies":[{"type":"txt","msg":"\"菜叔叔������\"语音课开课啦！"}],"ext":{"kHXMessageExtKeyBroadcastImgUrl":"","KHXMessageExtType":"1300","kHXMessageExtKeyBroadcastSubTitle":""菜叔叔������"语音课开课啦！","kHXMessageExtKeyBroadcastTitle":"呵呵","kHXMessageExtKeyBroadcastID":"2267"}}
 
 
加粗字段json出问题，应该是存消息的时候转json出现的双引号转出错了，这个问题挺严重的，每次群聊天出现双引号了退出应用重进就会只能拉起一条消息了，以前的全都拉不出来了
