Getting reference to nested fragment from FragmentTabHost

android, android-fragments, android-nested-fragment, android-tabhost

Solution

Well, exploring the source code of `FragmentTabHost` I've found that when it adds a fragment tab, it assignes a tag of `TabSpec` to nested `Fragment`.

So to get the reference to this `Fragment` we should call

`getChildFragmentManager().findFragmentByTag(tabSpecTag)`

Problem

In my application, I use an `Activity` which holds one `Fragment` with `FragmentTabHost` and hence all its tabs are `nested Fragments`. Inside an `Activity` which holds a `Fragment` with its `nested Fragment`, we may get a reference to attached one using `onAttachedFragment()`. But how to get a reference to `nested Fragment` from `FragmentTabHost`?
