copied!<p>This is a really good question!</p> <blockquote> <p>I think one can safely rule out the possibility of the Service probing for the current configuration to decide what activity to target with the PendingIntent.</p> </blockquote> <p>I'd agree that it would be preferable to keep UI decisions at the UI layer, but having the service make the decision would certainly be an expedient choice. You might use a static method on a UI layer class to keep the decision code technically outside of the service (e.g., a static <code>createArticlePendingIntent()</code> method on <code>NewsReaderActivity</code> that the service uses to build its <code>Notification</code>).</p> <blockquote> <p>So, how does one decide what activity to launch from a notification, if the activity to launch depends on screen configuration?</p> </blockquote> <p>Use a <code>getActivity()</code> <code>PendingIntent</code> for <code>NewsReaderActivity</code> in your <code>Notification</code>, with enough extras that <code>NewsReaderActivity</code> knows that it is in this "show the article" scenario. Before it calls <code>setContentView()</code>, have it determine if <code>ArticleActivity</code> is the right answer. If so, <code>NewsReaderActivity</code> calls <code>startActivity()</code> to launch <code>ArticleActivity</code>, then calls <code>finish()</code> to get rid of itself (or not, if you want BACK from the article to go to <code>NewsReaderActivity</code>).</p> <p>Or, use a <code>getActivity()</code> <code>PendingIntent</code> for <code>ICanHazArticleActivity</code> in your <code>Notification</code>. <code>ICanHazArticleActivity</code> has <code>Theme.NoDisplay</code>, so it will not have a UI. It makes the decision of whether to launch <code>NewsReaderActivity</code> or <code>ArticleActivity</code>, calls <code>startActivity()</code> on the right answer, and then calls <code>finish()</code>. The advantage over the previous solution is that there is no brief flash of <code>NewsReaderActivity</code> if the end destination is <code>ArticleActivity</code>.</p> <p>Or, use the <code>createArticlePendingIntent()</code> option I mentioned in the first paragraph of my answer.</p> <p>There may be other options as well, but those are what come to mind.</p>
