He misses a lot of the intricacies of the Android design site ( http://developer.android.com/design/index.html http://developer.android.com/design/index.html ). You are actually recommended to make your content touchable rather than putting every action in the top right as an icon. If I made a weather app, for example, I may have little day or hour graphics that can be tapped for more about that item. Even for the action bar there is a split mode that puts actions on the bottom as well. Similarly, he has the density classes wrong. There's XXHDPI, XHDPI, MDPI, and LDPI and they don't correspond to set resolutions. It's recommended by the Android Developer blog to actually change layouts based on a certain DP width (DP being a density independent pixel that normalizes measurements across density classes) rather than do x sizes of the same screen for each density. E.g. so screens with a lot of pixel real estate across get an extra list on the left, things like that.
