Advice from Google Developers isn't exactly consistent on this point, then. >From this page: http://developer.android.com/intl/de/resources/articles/avoiding-memory-leaks.html " The second solution is to use the Application context. This context will live as long as your application is alive and does not depend on the activities life cycle. If you plan on keeping long-lived objects that need a context, remember the application object. You can obtain it easily by calling Context.getApplicationContext() or Activity.getApplication()." Romain and Ms. Hackborn should probably talk. First, we should use an application context to avoid storing the Activity context. Second, we should use an Activity context because an application context plain won't work. Perhaps these aren't in conflict. If you have to store a context beyond the life of an Activity (something to be avoided when possible), you are stuck with the application context and whatever limitations it has. I don't know what Google Analytics does with the context; I'd guess they use the file system for temp storage. I don't if I'm allowed to reverse engineer the jar to find out, because the terms and conditions page is down.
