d.dump() missing views then stuck in bad state

I keep hitting a bug where resource IDs suddenly disappear, even though the device state hasn’t changed and can verify in uiautomatorviewer. I’m able to reproduce the bug in as few lines as:

# At home screen of device tested
>>> from uiautomator import device as d
>>> d.server.stop()  # Make sure we are in a good state
>>> d(resourceId='android:id/navigationBarBackground).exists
True
>>> d.dump()  # Does not show the full view hierarchy, navigationBarBackground missing
>>> d(resourceId='android:id/navigationBarBackground').exists
False

At this point it will continue to return False until I restart the uiautomator server or kill the adb service.

To find a specific example, take a uiautomator dump with uiautomatorviewer first, then take one using the Python wrapper. Nodes that appear near the bottom of uiautomatorviewer do not always show up in d.dump().

Environment info

uiautomator: 0.2.6 device: Amazon Fire HD 6 OS: Ubuntu 14.04 LTS

Note this isn’t reproducible by using d.dump(compressed=False). I think what’s happening is that AutomatorServiceImpl.dumpWindowHierarchy is setting device.setCompressedLayoutHeirarchy(compressed), but never changes it back to uncompressed. Once d.dump(compressed=True) is called, all calls after reuse device and return a compressed view hierarchy resulting in missing resource IDs.

I am also facing same issue 😦
