Nested fragments no view found for id

I am working on simple application having nested fragments with tab layout. Parent activity is LandingActivity. Inside of the LandingActivity i am calling LandingFragment. Inside of the LandingFragment i have following functionlity.

Tasks TAB Fragments flow is TasksMainFragment->TasksFragment->DetailFragment.

Pending TAB Fragments flow is PendingMainFragment->PendingFragment->PendingDetailFragment

The following code represents calling TasksFragment from TasksMainFragment. 

TasksFragment fragment=new TasksFragment();
        FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
        FragmentTransaction fragmentTransaction=fragmentManager.beginTransaction();
        fragmentTransaction.add(R.id.id_frame, fragment, "tasks");
        fragmentTransaction.addToBackStack("tasks");
        fragmentTransaction.commit();

Below code represents calling DetailFragment from TasksFragment. Basically TasksFragment contains recyclerview with some tasks. When user tap on the task it will open the DetailFragment of the task.

Fragment fragment = new DetailFragment();

        FragmentManager manager = ((FragmentActivity) mContext).getSupportFragmentManager();

        FragmentTransaction fragmentTransaction = manager.beginTransaction();
        Bundle bundle = new Bundle();
        ItemModel item = list.get(position);
        bundle.putSerializable("item", item);
        bundle.putBoolean("having", havingStartedService());
        fragment.setArguments(bundle);
        fragmentTransaction.replace(R.id.id_frame, fragment, "details");
        fragmentTransaction.addToBackStack("details");
        fragmentTransaction.commit();

When the user switch to pending tab same behaviour or same functionality will work. But the problem is when i open application after some time or open application first time on morning everyday i am facing this problem.

Other scenario when i change the screen orientation also i am facing this problem.

I am posting logcat below for better understanding.

By using getChildFragmentManager() instead of getActivity.getSupportFragmentManager().i resolved both crashes.

For Opening TasksFragment i am using below code.

FragmentManager fragmentManager = getChildFragmentManager();

For opening DetailFragment i am using below code.

FragmentManager fragmentManager = getActivity().getSupportFragmentManager(); in tasks tab. In pending tab also i am following same way to resolve crashes.

Now i am facing other issue. I am checking which fragment is visible to the user in both TasksMainFragment and PendingMainFragment. Because i am opening two fragments in both main fragments. So depends upon that i want to update UI of the visible fragment.

By using below code i am checking which fragment is visible to the user.

    Fragment f1 = getActivity().getSupportFragmentManager().findFragmentById(R.id.id_frame);
if (f1 instanceof TasksFragment) {
                Log.d("", "GCM Receiverf1task:Tasks");
//                ((TasksFragment) f1).updateUI(message, order);
            }
            else if (f1 instanceof DetailFragment) {
                Log.d("", "GCM Receiverf1task:Tasks Details");
//                if(message.contains("Started") || message.contains("Completed") || message.contains("cancelled"))
//                    ((DetailFragment) f1).updateUI(message, order);
            }

But when i am in TasksFragment the above code is not working. When i am in DetailFragment above code is working fine. Please help me to resolve this issue or let me know if anything wrong in my way.
