Fragment

This package is part of the Android support library which is no longer maintained. The support library has been superseded by AndroidX which is part of Jetpack. We recommend using the AndroidX libraries in all new projects. You should also consider migrating existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library class mappings.

Static library support version of the framework's Fragment. Used to write apps that run on platforms prior to Android 3.0. When running on Android 3.0 or above, this implementation is still used; it does not try to switch to the framework's implementation. See the framework Fragment documentation for a class overview.

The main differences when using this support version instead of the framework version are:

• Your activity must extend FragmentActivity
• You must call getSupportFragmentManager() to get the FragmentManager
