i am having listview in my view pager and i have used TitlePageIndicator. Everything seems to be working fine but randomly it crashes due IndexOutOfBound exception. I am not sure what is the cause for it. Below i have attached the stacktrace of it. Also i found this link and its mentioned that this has been fixed in 2.1.0. But i am using the 2.3.1 version.

It's a little hard to pinpoint your exact problem without seeing some code, but let me attempt an educated guess.

Is there a chance that you're accessing your adapter by manually calling getAdapter() on your ListView?

If so, instead of calling getAdapter(), when you're initially setting the adapter, keep a reference to it in a new class variable. Then, when you need it, access it using your new variable.

I've just solved my problem which is similar with yours. In my case it's because I clear my arraylist right before my asynctask runs. So what Im saying is when I scroll my List View, my array list is empty, to let the adapter knows the arraylist is changed and empty I have to notify it first.

arraylistTimeline.clear(); adapterTimeline.notifyDataSetChanged(); <--- wasnt here when error occure like you mentioned

TimelineRestoURL tURL = new TimelineRestoURL(); tURL.execute();

Just like that. Hope it helps.
