  • How to retrieve current location by using the new FusedLocation API from an IntentService?
  • How can i make sure that IntentService will receive all callbacks from FusedLocation API? ie, How can i obtain the location object synchronously?

    Start by replacing the `IntentService` with a regular service. `IntentService` does not handle calling APIs that are themselves asynchronous, like the fused location provider API. You will need a regular service, with your own background thread (where needed), where you can shut down the service only when you get your data (or some timeout it reached). "How can i obtain the location object synchronously?" -- there is no guarantee that you can, which is why you replace your `IntentService` with a regular service. – CommonsWare Apr 28 '15 at 11:32

    Please note that Service (as opposed to IntentService) works in the application's main thread. By not creating your own thread in this service you will block application UI thread which may lead to bad user experience. – sdf3qrxewqrxeqwxfew3123 Dec 21 '15 at 15:05
