method Lcom/etsy/android/grid/ExtendableListView;.fillGap incorrectly overrides package-private method with same name in Landroid/widget/AbsListView;
method Lcom/etsy/android/grid/ExtendableListView;.getFooterViewsCount incorrectly overrides package-private method with same name in Landroid/widget/AbsListView;

This issue (with fillGap) causes crashes on Android 5.0 when using support v7:

I got the same error as well

[Frank1234]

me too. Thinking about switching to recyclerview.

I have also encountered this error, and googled it to find this page. It seems to be intermittent and related to the StaggeredView

Apparently the issue may have to do with how you scroll on the emulator and doesn't happen on the device. From a student in the Android bootcamp we run:

This appears to be only present when not dragging and moving on the simulator, but swiping with the trackpad. I don't have a phone to test this out on, but it works perfectly fine with a click + drag.

i'm also facing a similar problem, with Android 5.0.2 in a Nexus 7 when trying to do do EtsyStaggeredGridView.scrollListBy(int). Did anyone manage to get a solution? please share it with us if so, thanks

[tnguyenquy]

Just look at Nathan's answer.

hey @hugogz I'm having the same problem and with a device too! It is just a particular moviment on scrolling the screen to get this error :/ any other gesture works fine

[namanjain1993]

I can confirm, this issue is only with trackpad, if u scroll holding click and swipe, it swipes flawlessly

[castasat]

This helped me with this issue, maybe will be useful for someone else:

1. Open the Settings or Preferences dialog: On Windows or Linux, select File > Settings from the menu bar. On Mac OSX, select Android Studio > Preferences from the menu bar.
2. Navigate to Build, Execution, Deployment > Instant Run.
3. Uncheck the box next to Restart activity on code changes.
4. Choose File > Invalidate Caches / Restart...
5. Rebuild your project
