porting to android

I have been working on brew platform from a long time now. For a change I am now presently looking into the android platform. Intially I was thinking that android platform would be similar to that of J2ME. But it isnt so. Only the basic J2ME libraries are supported in android. The application structure, activites, tasks and threading mechanism is quite different than J2ME. This means that for an application to port from J2ME to android is as tough as porting it from any other platform. But the number of API's supported by android is very good which makes porting to this platform easier. This is only my first impression of this platform, have to see how it goes...
