monkeyrunner Running getChildren() on view will cause "Node with given ID does not exist exception"

Question

I have nav drawer with "Settings" as TextView without an ID. I can get the home_nav_view but when trying to iterate over the children I get the exception "com.android.chimpchat.core.ChimpException: Node with given ID does not exist"

Am I doing something wrong?

>>> c = easy_device.getViewById("com.catonetworks.vpnclient:id/home_nav_view")
>>> print c.getLocation().right
840
>>> print c.getLocation().bottom
1794
>>> print dir(c)

>>> print c.getChildren()

Answer 1

The problem is that under the view there are Preferences and Android converts them to TextView that is why they don't have ID
