Android Error: "commit Already Called" When Remove A Fragment

I want to implement an activity that has a fragment! when I click on Fragment1 , Fragment2 is called , and when I click on Fragment2 , Fragment2 should be removed from the screen!

Solution 1:

Instead of reusing the passed-in transaction, create a new FragmentTransaction instance that removes Fragment2.

Even easier is to add the first fragment transaction to fragment back stack (e.g. addToBackStack(null)) and then in Fragment2, just pop the back stack with FragmentManagerpopBackStack().

Solution 2:

Begin new transaction

fragTran = fragMan.beginTransaction();
fragTran.replace(R.id.frag_cont_two, fThree);
fragTran.addToBackStack(null);
fragTran.commit();

Solution 3:

I solved the issue after calling commit() and again replacing the fragment you should start from

fragmentTransaction = fragmentManager.beginTransaction();
