As many people complaints and it is somewhat valid argument that this life cycle is too complicated, in Google I/O 2018,They have suggested to use Architecture component Framework. Please check this Docs

Solution 3:

when you are at Activity2---->backpress--->Fragment2(Activity1)---means Activity1 again attach from fragment2 so on OnAactivityCreated() method Activity1 is completely loaded ....so at that we can call setData() method of your Activity1...

Solution 4:

onAttachFragment()-activity is called before onCreate()-activity and after onAttach()-fragment

Solution 5:

Call onDestroy on onStop of your fragment. This should call onCreate when the fragment is launched. Let me know if works as an ideal solution for your problem.
