Solved - but absolutely no idea how - updated everything - rebuild, etc... https://dl.dropboxusercontent.com/u/2445259/2014-10-01%2022.15.23.png
and this surprised me as well C:\Users\admin\Downloads>fc "app-debug(1).apk" "app-debug.apk"
Comparaison des fichiers app-debug(1).apk et APP-DEBUG.APK
FC : aucune différence trouvée - no difference between the generated apks, same install method... I guess this is not a generic issue with 4.2.2 that you'd have to worry about in the release.
