Add local Library Project as a dependency to multiple Projects in Android Studio
You can also refer to a library outside of your project folder using the project().projectDir property. If your external library is relative to your project like so – MyLibrary – library – MyProject – app in MyProject/settings.gradle include ‘:library’ project(‘:library’).projectDir = new File(settingsDir, ‘../MyLibrary/library’) in MyProject/app/build.gradle dependencies { compile project(‘:library’) }
