DriveEventService

    • DriveEventService is an abstract Android service for handling Google Drive events like changes and completions.

    • Subclasses must override listener methods to process specific Drive events.

    • The service uses AIDL calls to receive events and raises corresponding listener events.

    • To be functional, subclasses must be declared as an exported service in the Android Manifest with a specific intent filter.

    • It implements ChangeListener and CompletionListener interfaces from the Google Play services Drive API.
    public abstract class DriveEventService extends Service
    implements ChangeListener CompletionListener

    Abstract base class for a bound service that handles all DriveEvent instances. These events will be delivered using AIDL calls to the service. The base class handles binding and handling of these calls and will raise listener events on the subclass.

    Subclasses should override one or more of the following interfaces depending upon the event types that expected by the application:

    The default implementation of all listener methods ( onListener ) methods will log an unhandled event warning to indicate that an unexpected event type was received. Subclasses should override these methods for any expected event types to provide appropriate handling.

    The implementation subclass must be listed as an exported service in the Android manifest for the application. The following manifest fragment shows a sample declaration with the required attributes:

    <manifest xmlns:android="//schemas.android.com/apk/res/android"
   <service android:name=".MyAppEventService" android:exported="true" >
     <intent-filter>
       <action android:name="com.google.android.gms.drive.events.HANDLE_EVENT" />
     </intent-filter>
   </service>
 </manifest>
