AIDE takes a very, very, long time to dex a library, especially the v4 Support Library. It will sometimes take 10+ minutes on my phone (Android 4.1.2, 1GHz Qualcomm, 512MB RAM). I would like to see either background dexing of the libs, faster dexing, or pre-dexed libraries (SHA-5 hash?), copying the dex file to jardex. Also, please dex only one version of the library. Having a ton of libraries that each use the Support Library, using their own jars, it can really take forever to compile.
