The problem you're facing is with incompatibility between android.app.Fragment and support.v4.Fragment. These two are not the same, and each has it's own FragmentManager they work with.

You are using getSupportFragmentManager which means your fragment should extend support.v4.Fragment (check the imports, and change to this). Either change that or get the other fragment manager by calling getFragmentManager.

I'd personally suggest working with the support library, since in one of my projects, it proved good to me, while I had various problems with the other one, but this is purely my opinion.

That does not matter. Remove the `android.app.Fragment` import and leave only the `support.v4.Fragment`. Do this in your `MustVisitFragment` – Vucko Jul 09 '16 at 15:22

Replace android.R.id.content with R.id.container

Add imports:

import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;

Will solve your issue.
