Ah, I see, you have a circularity in that the ArrayAdapter refers to the 
BlinkAPI instance, but BlinkAPI needs access to the ArrayAdapter.

It seems to me you need to separate UI code from data-model code to break 
the cycle. How about doing this:

* Define a class, say BlinkItem, that contains all the state for a single 
item in the list, with no reference to any UI widgets.
* Define a subclass of ArrayAdapter<BlinkItem> which implements the UI for 
displaying/manipulating a list of BlinkItems.

How does that sound?
