Android how to use static inner AsyncTask class

S1

To prevent leaks in memory, you can make the inner class static.

The problem with that, though, is that you no longer have access to the Activity's UI views or member variables.

You can pass in a reference to the Context but then you run the same risk of a memory leak. (Android can't garbage collect the Activity after it closes if the AsyncTask class has a strong reference to it.)
