How to share an editable android project with git and sourcetree

Question

I need to share an android project with another pc and still be able to edit it on both sides. For some reason I can't get this to work. I have tried a lot of different combinations to import it and still be able to edit and push changes. When I try to import the project into my workspace, there is a lot of errors like this:

the type java.lang.object cannot be resolved. it is indirectly referenced from required .class files

Then I tried importing the JRE System library (JRE 7) After doing this I still get errors. for example this:

Activity cannot be resolved

Then I imported the Android library to the project (API 18). But after doing this, there is a red cross on the project, but not in any classes, files or like..

Therefore I tried to clean the project, which removed the "R.java" and gave me a bunch more errors.

I don't know exactly what I am doing wrong here so I hope someone can help me out.

What is the "right" way to import eclipse projects and still be able to edit and push/pull?

(Btw. I am using BitBucket and SourceTree and trying to import it into my eclipse workspace. )

Answer 1

Found out what was wrong. By navigating to "Window > Show view > Problems", I found out that the necessary API wasn't available at that eclipse version. So I downloaded it the software and it worked.
