IssueTracker

Seems to be a DNS problem with systems that have 'obtain DNS server address automatically'. Changed my system to a manual setting and the browser etc now work. SDK 2.2 didn't seem to mind the auto setting though.

Could you please describe how/where you changed your system to a manual setting?

Based on its date, this issue was originally reported before Android 2.3. Because of the many changes that existed in Android 4.x compared to previous versions, it's very likely that this issue doesn't exist in recent versions of Android like 4.2.2 or newer. Because of the high likelihood that this issue is obsolete, it is getting closed automatically by a script, without a human looking at it in detail. If the issue still exists on a Nexus 4 or Nexus 7 running Android 4.2.2 and is not related to Google applications, please open a new report accordingly.

commit f418aaa3dc3d8517dafdd1fba5af6ec0c16dc7d4
Author: Jelle Fresen <jellefresen@google.com>
Date:   Mon Jul 29 13:16:41 2019

    Fix mCurrentItem and events when data set changes
   
    If the data set changes during a smooth scroll and the first visible
    item is removed in this change, the smooth scroll may land on another
    page then expected.
   
    Fix this by dispatching a selected event and an idle event when RV
    transitions to idle and we are not yet idle (and a few more specific
    conditions).

    Fix epsilon offset in test_removeFirstVisibleItemWhileScrolling
   
    Epsilon needs to be subtracted instead of added.
   
    Consider the case where targetBound = false. The window of opportunity
    for the test is while scrolling between 3 and 2 pages before the target,
    so the 'distance' parameter for addWaitForDistanceToTarget should be
    3 - epsilon. 'targetPage - windowStart' gives 3 (see calculation of
    windowStart), so subtract epsilon from that.

    Add more tests for data changes while scrolling
   
    Creates a new parameterized test to tease out different modifications of
    the adapter's data set while smooth scrolling. Note that while the
    expectedFinalPage and expectedFinalPageText are not what you'd expect
    intuitively, it is fine to hardcode them as they are not determined by
    ViewPager2, but by an external and constant factor (RecyclerView).
