A. Android Studio Remote Dependency Library Option

If using Android Studio with remote dependency libraries then use the following in the build.gradle

compile fileTree(dir: 'libs', include: ['*.jar'])

}

B. Android Studio Jar file Option

If you want to remove GPS from an existing project and just use the jar then here are the steps required.

Removing GPS from an existing project to just include google-play-services-basement.jar. For example the out of the box Tapjoy EasyApp sample includes the entire GPS library. Listed below are the steps showing how to remove this and just use the required google-play-services-basement.jar.

Remove references to GPS in the following locations

1. Settings.gradle – showing commented out include.

//include ':Libraries:google-play-services_lib'
include ':TapjoyEasyApp'

2. project.properties.- showing commented out reference to GPS

#android.library.reference.1=../Libraries/google-play-services_lib

3. Remove from reference of gps in the build.gradle and add the google-play-services-basement.jar’ jar file.

dependencies {
compile fileTree(include: '*.jar', dir: 'libs')
//   compile project(':Libraries:google-play-services_lib')
   compile files('libs/google-play-services-basement.jar')
}

4. AndroidManifest.xml. showing commented out reference to GPS

<application
android:icon="@drawable/icon"
android:label="@string/app_name" >
<!--     <meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />-->

Another method is to include an entry into the gradle.build that allows for multidex support. See the following link for more details on this:

Unity has an option to create an android project instead of .apk. Then you can make the modifications suggested above.
