This tool is usefull to display informations about screen resolution and on density for devices. It will able to display the screen resolution, the aspect ratio of screen, if screen is in landscape mode, the density class (ldpi, mdpi, hdpi, xhdpi, xxhdpi, xxxhdpi), the scale factor and the device screen density. There is a image large 100dip. I put it just to display conversion between dp and inc and conversion between dp and mm.

Moreover, i added:
- a calculator for dpi conversion , so you can easily find the right dimensions for dpi categories.
