For some time, Motorola Mobility has offered its MOTODEV Studio for Android suite as a standalone alternative build on Eclipse. A lot of developers seemed to like the additional tools Moto built into Studio, but weren't exactly keen on dropping Eclipse in exchange for Moto's less open solution.
Now that Motorola is a part of Google, it seems that state of affairs just won't do. Earlier today, on the official Motorola blog, the company announced it was open sourcing key parts of MOTODEV Studio and merging them into the Android Open Source Project. Looking at the commits (here), head of the ADT/Tools team at Google, Xavier Ducrohet, seems to have been involved extensively in the process.
From here on out, these special add-ons will be known as the Motodev Core Plugins, and you can actually just add them on top of your current Eclipse install. Find the instructions here.
So how about that Android / Motorola "firewall?" Looks like somebody left a couple ports open.
