However, there is a difference in communication between the handling of Android screen rotation and the validation of user input that has led me to address this issue. For example, if you read SQL tutorials or learn about it on StackOverflow, everyone will tell you again how important it is to validate input, and that this is not to be neglected. On some Android topics like screen rotation for example, you can often find popular answers on StackOverflow that promote a "wrong" solution.
