Not only is it not an Activity, but an Application -- it may not even
be YOUR Application in some cases.
You should never use getApplicationContext(). Just use the current
activity itself, or if you need YOUR application, call
getApplication().
Accessing other activities is a mistake. It requires you to keep a
reference to them to access them - and that prevents their storage
from being garbage collected. Perhaps you need to refactor some of
your code into a separate common class, or to place your common code
on your Application class instead?
Either way, you do need to be careful. Neither the Application, nor
the common object, should hang onto things relating to activities. No
view instances, and no data that is only needed within a specific
activity.
