My 1st Android App - Sudokroll

I know how to solve Sudoku puzzles but have never solved one by myself. I'm just too lazy to do that.

I developed a Sudoku solver a while ago. It has a command line interface, so just input your puzzle as follows and it'll get solved.
_____8_7_
91___45__
_7_5__8__
_3__86_5_
7_______3
_4_12__8_
__2__7_6_
__34___21
_9_8_____
Pretty cool, huh?

As I always said, Android development is a bonus to Java developers. I ported my Sudoku solver and made it an Android application. It's called Sudokroll. As the name suggests, you touch a cell and scroll on the screen to assign a number for the cell.

For better look and feel, it's for Android 2.3 Gingerbread and above. Have fun.
