4. What is Android Oreo?
5. "Coming hand-in-hand with the Android Oreo release is a female superhero (think: green Android mascot with a belly made from an Oreo), which the brands say is meant to mix the "playfulness" of Oreo and the "intelligence" of Android."

20. Background Execution Limit java.lang.IllegalStateException: Not allowed to start service Intent { act=xxxx cmp=xxxx.xxxx.xxxx }: app is in background
21. Android 8.0 (API level 26) also includes the following changes to specific methods: https://developer.android.com/about/versions/oreo/android-8.0-changes.html The startService() method now throws an IllegalStateException if an app targeting Android 8.0 tries to use that method in a situation when it isn't permitted to create background services. The new Context.startForegroundService() method starts a foreground service. The system allows apps to call Context.startForegroundService() even while the app is in the background. However, the app must call that service's startForeground() method within five seconds after the service is created.
