Adding Google Play Services support to your project
As per the Google Play Services setup guide, one does not simply "add the jars". Since GPS comes bundled with resources, you have to import it as a new seperate project, and reference it from your own, exisiting project.
Please follow the setup guide. I've just verified that I can reference AdView
successfully from my own project incorporating GPS.
Ensuring your device supports Google Play Services
GPS is an external service - it's an APK managed by the Play Store app and you need to ensure that the user has the latest GPS APK and/or one that complies with what you wanna do. Here is the guide: Ensure Devices Have the Google Play services APK.
If the device does not have GPS installed (not a Google device, special ROM, AOSP ROM, old Android, etc...) you can not use AdView.
