why editText retained it's value during screen rotation?Which is contradictory to what we saw in fun facts project.
Actually on the FunFacts we used TextViews instead of EditTexts.
TextViews values won't be saved automatically different than EditText because on EditText there is a flag called "freezeText' that is set to "true" by default, but you can make the TexView do the same by setting the "freezeText" flag to true via xml android:freezesText="true" or TextView#setFreezesText(true) on the widget. Otherwise you will have to make it manually as it was done on the FunFacts app.

If I remember right, that is just a sort of courtesy the system provides for you since it is such a common thing. It is most likely stored in the savedInstanceState Bundle and restored for you then after rotation/recreation.
I have the same question too. Don't we name all our view ids "uniquely" in the Fun Facts project ?
