Fear No Fragments
summary
Shows concrete fragmentation patterns: managing fragment transactions and the back stack, using child fragment managers to avoid confusing hierarchies, and preferring ViewModel for async state to avoid IllegalStateException. Demonstrates headless fragments for retained work and a pragmatic trick to persist a WebView by hide instead of replace so the hybrid World Cup app keeps its web app alive. Includes lifecycle checkpoints to check isAdded and examples of commit vs commitAllowingStateLoss.
