Because of varieties of screen size and density of Android phone, it is very hard for Android developers and Android UI designers to work on Android devices. To create an Android app, we try to do our best to make it compatible as many Android devices as possible. Therefore, I think it is necessary to summarize an Android device screen size and density table to help android developers and designers to check from time to time. This table doesn’t cover all the android phones and tablets.
