Question

I’ve an application in the market and many users have reported that the app is crashing a lot randomly. I’m trying to fix this but cannot fully understand the logs. Here’s a extract from the log,

I got this log from one of my users.

Any help on this would be very very helpful.

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???

Answer 1

My guess is that:

• You have an activity containing a TabHost (fine)
• The contents of those tabs are activities (bad)
• You are duplicating android:id values among some of the widgets in those activities (fatal)
