Is it better to use fragments or activities
Fragment cannot be used without an Activity. When using fragments in the project, the project structure will be good and we can handle it easily after using multiple fragments in a single activity.
When should you use a fragment over an activity
4 reasons to use Android Fragments
- The Activity class is frequently considered to be the primary UI class in Android, handling variations in device form factors.
- information transfer between app screens.
- organization of the user interface.
- sophisticated UI metaphors.
Why are fragments used
According to the Android documentation, a fragment is a user interface component of an application that is bound to an activity. Fragments help to enhance your UI design, pass information between different screens, and adapt to various device configurations.
Is Fragment life cycle dependent on activity life cycle
Fragments were added to the Android API in Android 3.0 with API version 11 to support flexible UI on large screens. A fragments life cycle is closely related to that of its host activity, meaning that when the activity is in the pause state, all of the available fragments in the activity will also stop.
Should I use fragments
Fragments should make it simpler to support different screen sizes, even though you dont need them to do so. For example, you should be able to instantiate the same fragment as a full-screen activity on a phone or as a partial screen on a tablet with just a few lines of code.
