`compile project(':` means that the argument has to me in the same directory of your project. Do you have a module called `androidHorizontalListView` ? — Blackbelt, Apr 28 '15 at 07:05
Take a look here, it's explained very easy: http://stackoverflow.com/questions/16588064/how-do-i-add-a-library-project-to-the-android-studio?rq=1 — Nike Sprite, Apr 28 '15 at 07:15
Why library apply plugin: 'com.android.application' change it as apply plugin: 'com.android.library'.show me the gradle sync is failed error log.? — Anoop M Maddasseri, Apr 28 '15 at 07:20
@Blackbelt dn't know but i added library as file>import module and then through project structure. Also editing my structure. — user3519331, Apr 28 '15 at 07:21
http://www.truiton.com/2015/02/android-studio-add-library-project/ also update the sdk versions of library like app's gradle. — Anoop M Maddasseri, Apr 28 '15 at 07:25

at first you should setup your library with the appropriate plugin:

com.android.library

instead of

com.android.application

Second step would be also to setup the settings.gradle file in the project root containing all sub projects to get the references working: It should contain:

include: ':app',':androidHorizontalListView'

Please try again to compile the project.

There is an Easy way to do it select file from left of Android Studio then select New Module-->Import Existing Project-->Browse the location of your library-->finish

Also add compile project(':your library') in apps build.gradle that's all.
