I\'m developing a Java ME app & need pointers to some really good UI libraries. I did see a few such as Java ME Polish. Are there any more out there? For e.g. ebuddy\'s
Most of the apps with amazing UIs (Opera Mini, Gmail, any game from an AAA developer) use custom UIs developed in-house. These developers take the task of developing an UI as one more in their projects and give it personality, involving professional graphic designers. Going with a packaged library would quickly accomplish the task but it would make the application look generic and bland (less bland that with the default UI, but still bland and limited).
In short, go with a packaged UI for quick development, but don't expect the level of quality to be near the apps you mentioned.
