Android Fragment back stack causing wired issue -

i having fragment in single activity in following sequence.

fragment 1 --> fragment 2 --> fragment 3 --> fragment 4

i using below code fragment transaction.

mfragmenttransaction=mfragmentmanager.begintransaction(); mfragmenttransaction.replace(r.id.fragment_container, mfragment,fragmentname); mfragmenttransaction.addtobackstack(tag); mfragmenttransaction.commit(); 

what want when user on fragment 3 or 4 on press if user on fragment 4 fragment 4 --> fragment 3 --> fragment 1. if user on fragment 3 fragment 3 --> fragment 1.

i using following code in onback press.

if(mfragmentmanager.findfragmentbytag("fragment 3")!=null){               mfragmentmanager.popbackstack("fragment 2",fragmentmanager.pop_back_stack_inclusive);            }else{             super.onbackpressed();         } 

but cause wired issue on on press follow.

fragment 4 --> fragment 1 instead of fragment 4 --> fragment 3 --> fragment 1. fragment 3 --> fragment 1

please .

you need have nested if statement. have 1 check if fragment null or not, need check if fragment visible.

if(mfragmentmanager.findfragmentbytag("fragment 3")!=null){      if(mfragmentmanager.findfragmentbytag("fragment 3").isvisible()){         mfragmentmanager.popbackstack("fragment 2",fragmentmanager.pop_back_stack_inclusive);     } } else{         super.onbackpressed(); }
