I have an ".apk" file, In this, I want to change the behaviour of the status bar. I'm able to modify its files in "res" folder but I want to write new code, so I've downloaded what I understand is the project link
My question is: How can I compile it? it seems to be a part of a much more generic project, I've read people in internet saying it's possible but I'm not able to import lots of referenced classes (com.android.internal.R for example).
I'm sorry if it's a newbie question or if it's not clear enough, but if someone who has done this before could help I'll be grateful
