This is an app meant for developers or people who are just curious about their Android device. Full source available: https://bitbucket.org/mveroukis/juanitaThere are so many different devices and its often not obvious how each device is configured. Android uses configuration qualifiers for its resources, which means you can use different sets of resources depending on the screen density or orientation. Sometimes its not obvious what a particular devices screen size or screen pixel density is, but Juanita will tell you.The app hardly has any code, all the logic is done by the Android system. String resources have been created for most resource configuration qualifiers (ex: values-ldpi, values-large, etc) and those string values are displayed in a table. When Android loads the app it loads the appropriate resource based on the device configuration.
