Questions tagged [android-nested-fragment]

Nested android fragments represent fragments which are embedded in other fragments.

Nested fragments were introduced in the Android SDK starting with API level 4.2. They are also available on lower API versions through the support compatibility package.

By using getChildFragmentManager()(method of the Fragment class), a fragment can have the behavior of a FragmentActivity. The nested fragments workflow closely follows the one of a normal fragment(which is embedded at in an Activity). For more information about fragments, see the Google Documentaton.

When asking questions about nested fragments one should always add the tag, optionally the could also be added.
