Notes from Mitch Williams’ talk about AllJoyn on the 1st day of DroidCon UK 2012.

“AllJoyn™ is an open-source application development framework that enables ad hoc, proximity-based device-to-device communication that is OS agnostic.”

There are other frameworks like DLNA, UPnP and Bonjour as well. DLNA would be a good choice if you only wanted to do one-to-one device communication. UPnP and Bonjour are missing a lot of the higher level communication compared to AllJoyn.

AllJoyn is multi-platform as a result of the native implementation being written in C++. The currently supported platforms are:

• Android 2.1 and above
• iOS
• Window XP, 7 and 8
• Linux
• OS X
