Clone application as new project with original remote named "android-base"
```
git clone --depth 1 git://github.com/fs/android-base.git --origin android-base [MY-NEW-PROJECT]
```
Note: we use depth parameter here in order to not copy the history of changes in base project
Create your new repository on the GitHub and push master into it. Make sure master branch is tracking origin repo.

cd [MY-NEW-PROJECT] git remote add origin git@github.com:[MY-GITHUB-ACCOUNT]/[MY-NEW-PROJECT].git git push -u origin master
Import the project into your favourite IDE. Just select the root build.gradle and your IDE will do the rest.

Change your app's package by either renaming the folder structure for Java sources or by just changing this constant in build.gradle
