Hi; after a while i m back! with a post including some android experiences. Before start I want to mention that I have been developing on csharp for a long time so I want to mention that these Java tools made me sick for a while to get use to and work with but now I am a good hello world programmer at android. As a system I use 64 bit Windows 7 (i hear you say what a shame for a developer ). My Android development tools are Eclipse and Android SDK ofcourse.
