android - Close Activity using Fragment -

introduction

i have activitya starts fragment when click button. using intent can't start fragment, i've created second activity, let's call activityb acts bridge between activitya , fragment.

the structure : activitya --> activityb --> fragment

functionality

the functionality activitya, start fragment, request data, , bring data activitya.

for use startactivityforresult() in activitya call activityb. in activityb start fragment way:

fragment fragment = new fragment(); fragmenttransaction ft = getsupportfragmentmanager().begintransaction(); ft.add(android.r.id.content, fragment).commit(); 

when finish must on fragment, use setresult() send data activtya.

problem

the thing have started activityb initialize fragment, when returning data fragment activitya, activityb still 1 opened, , activitya remains on background.

this makes me not able process requsted data, activitya continues on background.

so, need know how close activityb when finish operations in fragment, go activitya , make visible.

you can use method getactivity().finish() method in fragment close activityb.
