Common mistakes when working with Fragments?

When working with Fragments in Android, developers often encounter common pitfalls that can lead to crashes, memory leaks, or unexpected behavior. Here are some mistakes to avoid:

  • Not using FragmentTransaction properly: Always ensure you commit your transactions correctly and manage the back stack.
  • Failing to detach and attach Fragments: Properly use detach() and attach() when needed to avoid memory leaks.
  • Ignoring the Fragment Lifecycle: Understand the lifecycle methods and their implications. For example, using network calls in onCreateView() might lead to unexpected behavior.
  • Not utilizing ViewModel appropriately: Using ViewModels can prevent data loss during configuration changes.
  • Not handling Fragment state restoration: Always save and restore the state when necessary in your Fragments.
