I am not an experienced developer by any means (I have only one app on the Android Marketplace), but I this is the way that I do it: -For any updates that are just minor bug fixes, then I update the Z. ie: 1.0.0 --> 1.0.1 -For any updates that add a pretty big feature of some sort, that's just more than a simple bug fix, then I update the Y., and reset the Z. ie: 1.0.3 --> 1.1.0 -For major updates that add a lot of features, and/or implement a new UI or something, then I update the X, ie: 1.1.2 --> 2.0.0. Again, I am not sure if this is the normal way, but it's how I do it.
