hope this fix your issue I have seen numerous similar questions on stackoverflow but I can not figure out what I am doing wrong. I have made a very simple app to replicate the error. , Pass a reference of MainActivity to the Dialog and try this
code :
mainActivity.addButton()

wish helps you When you rotate the device, Android saves, destroys, and recreates your Activity and its ViewPager of Fragments. Since the ViewPager uses the FragmentManager of your Activity, it saves and reuses those Fragments for you (and does not create new ones), so they will hold the old references to your (now destroyed) original Activity, and you get that IllegalStateException.
In your child Fragments, try something like this:
code :
@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
    Log.v(TAG, "onAttach");

    // Check if parent activity implements our callback interface
    if (activity != null) {
        try {
            mParentCallback = (Callbacks) activity;
        }
        catch (ClassCastException e) {
        }
    }
}
if(mParentCallback != null) {
    mParentCallback.onItemSelected(selectedLink);
}

will help you Your LeftMenuFragment is creating a new MainActivity in your onItemClick. This won't work.
Android creates activities on your behalf, and it should already be running and attached to your fragment. So instead, you should use the getActivity() method provided by Fragment to retrieve your MainActivity.
code :
MainActivity mainActivity = (MainActivity)getActivity();

if (mainActivity != null) // Make sure we are attached 
{
    mainActivity.displayFragment(arg2);
}

it fixes the issue Finally found it: i was calling newTab.mFragmentContainer.setDefaultContent(null); before committing the addition of newTab.mFragmentContainer and making sure it is executed. In other words, I was manipulating the ContainerFragment before it was properly added to view hierarchy.

To fix the issue you can do Someone posted another question similar and the problem is due to a bug in the ChildFragmentManager. Basically, the child FragmentManager ends up with a broken internal state when it is detached from the activity. Have a look at the original answer here
