NotificationListenerService get Notification Icon?
android, android-4.3-jelly-bean, notifications
Solution
Use `getPackageName()` on `StatusBarNotification` to find out the app that posted the `Notification`. You can then use `createPackageContext()` to get a `Context` for that package, then use that `Context` to retrieve the image (e.g., via `getResources()`).
Problem
In a Service extending the new (SDK18, JB-4.3) `NotificationListenerService`, I'd like to get the Notification's status bar icon. `mStatusBarNotification.getNotification().icon` returns the resource id of the status bar drawable, but that resource id is naturally not within my app's scope/resources. There's also `mStatusBarNotification.getNotification().largeIcon` (returning a `Bitmap`), but that's not set for all notifications and returns the "wrong" icon (the image in the expanded notification drawer).
