Regression from bug 722020?

Comment 2

Hrm, how is that happening? I purposefully set the header view before calling setAdapter:
http://mxr.mozilla.org/mozilla-central/source/mobile/android/base/AwesomeBarTabs.java#365

I guess maybe we can create a BookmarkQueryTask more than once? I'll look into this.

This is just a speculative fix, since I can't reproduce this issue.

Since the onTabChanged listener is checking to see if the adapters are initialized before making the AsyncTasks, it's possible that we can kick off multiple tasks to initialize the same adapter, which would lead to this crash. Instead, it seems like what we really want is to make sure we haven't already kicked off an async task, so this patch keeps track of whether or not that's happened.

I think the right fix is to have something like:

if (tabId.equals(BOOKMARKS_TAB) && mBookmarksAdapter == null && mBookmarksQueryTask == null) {
   ...
}

Which means you'd cover the case where adapter is already set or about to be set by the asynctask. You have to set mBookmarksQueryTask to null once the task is done.

Analogous solution here.
