What is the 'best practice' for changing from 'Activities' to 'Fragments' for Android applications?

Not really an 100% answer, but just my personal experience so far (and please correct me, anybody, if I got something wrong - I'm still a beginner to Android).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
