Internals of Android Architecture Components

" summary

Android Architecture Components claim to fix lifecycle and configuration-change bugs by using three core libraries: Lifecycle, ViewModel, LiveData. ViewModel actually uses an internal retained fragment to survive rotations, LiveData only pushes updates when the view is STARTED/RESUMED, and onCleared disposes subscriptions so network calls aren’t duplicated and context leaks stop. A SingleLiveEvent handles one‑time messages. Works cleanly with MVVM, can be bolted onto MVP as a hack, and integrates with RxJava/Dagger; example code shows two lines to get a ViewModel and observe LiveData.
