in android studio how git clone project github same project? if got question correctly, want check out library , add dependency (gradle based?) project. prefered way checkout separately , built library project. , if have maven can install local repository. the other way (and trying achieve) add submodule of local repository. git submodule add git://repourl.git yoursubmodulefolder then can add library module dependency application module. (you don't have use git submodules, can repo zip , extract project) if put library under libraries folder in project can this. add settings.gradle include ':libraries:yourlibrarymodulename' add build.gradle dependencies { compile project(':libraries:yourlibrarymodulename') } you should able build application submodule please note quick answer, can find more info on both gradle submodules , gradle module dependencies here on stackoverflow. guess should enough point in right direction.
