If you are designing for a touchscreen environment, don’t introduce too many panels and create clutter on the screen. Size and shape of buttons and links and their placement on the screen should be in such a way that the app can be smoothly and seamlessly operated. While Creating Android apps development tools should pack in innovative functionality, make sure new features are only added if existing ones are polished and will benefit most users. Check if the feature has the right degree of resource intensiveness for the older phones too. Try to come up with affordable options for the users.
