RPG Dice Roller

This application is a simple, bare bones dice roller for use with tabletop RPGs. It is ideal for users who are looking for a fast and efficient way to roll a variety of RPG dice types.

The user selects how many dice to throw, up to 10, and then chooses the number of sides per die. Currently, 2, 3, 4, 6, 8, 10, 12, and 20 sided dice are supported. When the dice are rolled the screen displays the value of each die thrown, as well as the total sum.

I am new to android development, and with this being my first application I would love to hear your feedback on how this or future applications could be improved.
