I just heard about the Droidcon London - I hope I can be there (*). The list of speakers looks very promising and the price is reasonable. Also, it would be great to talk with other Android developers (**). I never have been at an Android conference before.
(*) I’ll ask a friend if I can stay at his London apartment. A hotel would be too expensive for me at the moment. (**) Although I did not do much Android-development in the past few months I am still very interested in this topic.
