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.
