我从我的用户得到这个日志。
I got this log from one of my users.
任何帮助将是非常非常有益的。
Any help on this would be very very helpful.
问候， 哈日
我终于可以通过模拟器设置了50MB的内存和GSM网络的速度运行复制此问题。这个问题似乎是因为历史被清零，因此数据丢失该应用已经具有哪些。不知道我怎么可以处理这个，但..任何帮助???
I was finally able to replicate this issue through an emulator set up with 50MB memory and running on GSM network speed. The issue seems to be because of history being cleared and so the data being lost which the app was already having. Not sure how I can handle this though.. any help???
推荐答案
我的猜测是：
- 您有一个包含TabHost（罚款）的活动
- 在这些选项卡的内容是活动的（坏的） 在这些活动中的一些小部件的ID 值（致命）
- 您正在复制
安卓
- You have an activity containing a TabHost (fine)
- The contents of those tabs are activities (bad)
- You are duplicating
android:idvalues among some of the widgets in those activities (fatal)
