05/29/2019, 11:39 AMThere are a couple of libs and examples if you google "android input validation":

https://github.com/ShabanKamell/FormValidator
I haven't actually used any of these, but I am planning to implement the same thing into my application although I decided to make my own utility class to check user input from text fields. Hope it helps 😃

05/29/2019, 12:15 PMYes. If you want to follow the principles of navigation architecture component you should create an Activity which has a NavHostFragment. More info -> https://developer.android.com/guide/navigation/navigation-getting-started
For starters you can use this application architecture. There are some examples in this official guide -> https://developer.android.com/jetpack/docs/guide
