It is just a strait classical implementation of the Tetris. I shows drop position, next figure, increase speed with levels (up to 20), calculate score giving bonus for extra lines. And it saves score into phone’s memory, so you can keep track of records. It works perfectly fine on my Google G1 and my record so far is 18700. This is exactly the minimum of what would you expect of the game like this. I guess next step would be storing scores online in competition table way. Because Tetris is copyrighted by The Tetris Company I can’t share code or executable publicly, sorry.
So far I liked Android platform. They definitely did a good job for UI interface. Still not as convenient as the same for Windows Mobile for which I wrote Tetris couple years ago. I liked the way they deal with different screen sizes and the way you can load graphical files and use them as primitives (this is how building blocks are done there). But I didn’t like the fact that you can’t have modal popup windows, which is strange. I would do all small windows modal in some sense for this kind of devices. Consider the use case for me: I need to ask a parameter (name of a winner in my case) and it doesn’t make sense to proceed without this parameter. I simply didn’t find any way to do it in Android, so I went with a workaround. I love smartphones. It is fun that you can do something for your own phone.
