I have seen couple of Android applications when I came across one common practice. Navigation header does not have a Back button. Since then I was quite confused so as to place the same in the Navigation header of my application.
Should back button be placed in Navigation (Header) or we should leave keys to handle it? What is the best practice we should follow?
Thanks
My personal view is that each platform has its own way of handling certain functions. An apple device will have a back button on its navigation bar because that is the place where an iphone user will look for it.
As far as Android is concerned, because we are supplied with a physical back button, we must leave it at that because that is the first place an android user will look to if he wants to go back.
Therefore since user satisfaction and ease of use is the main concern, i would not play with the back button (unless i have to).
