On android studio create a simple application i need 1 fragment and 1 main activity. In main activity, on button pressed, create an instance of the fragment class. one Fragment for inserting a number (start with 1 in the first Fragment) and a button below it. Upon clicking the button, replace the first Fragment with a second Fragment and insert the number 2 in that Fragment. Continue this capability all the way up to 5, and while doing so, add each Fragment to the back stack to support back navigation. screens shot would be a great help
