Próbowałem dodać fragment wewnątrz innego fragmentu wewnątrz przeglądarki przy użyciu getChildFragmentManager()
. Mam następujący błąd,ChildFragmentManager java.lang.IllegalStateException: Działanie zostało zniszczone
java.lang.IllegalStateException: Działalność została zniszczona na android.support.v4.app.FragmentManagerImpl.enqueueAction (FragmentManager.java:1549) na android.support.v4.app .BackStackRecord.commitInternal (BackStackRecord.java:654) w android.support.v4.app.BackStackRecord.commitAllowingStateLoss (BackStackRecord.java:625) w com.lakeba.gameon.userprofile.UserProfileContainerFragment.replaceFragment (UserProfileContainerFragment.java:72)
Próbowałem this workaround, ale wciąż otrzymuję ten sam błąd.
