Android Screen Transitions


We can change the default transition in android but it is not necessary that our given transition apply every time. We should create some animation xml files and follow the steps below:
Steps to create activity transitions.
·         Create a folder in the res folder.
·         Named the new created folder as “anim”
·         Put XMLs of animation in it.
