Spb shell 3d rebuilding

I am very like spb shell 3d launcher, but it’s not maintain for a long time, i am plan to rebuild it to support android 5.0 and 6.0, but i need some help, who can give me some help?

i have decompile it and have not find code confusion, but i encounter lot of compile error from the AndroidManifest.xml file, i think, the format and xml syntax’s updating cause it, and i have a very slow pc, it’s difficult to rebuilding the project, is there anyone have interesting to participate in?
