-/**
- * Helper for the common pattern of implementing a {@link BroadcastReceiver}
- * that receives a device wakeup event and then passes the work off
- * to a {@link android.app.Service}, while ensuring that the
- * device does not go back to sleep during the transition.
- *
- * <p>This class takes care of creating and managing a partial wake lock
- * for you; you must request the {@link android.Manifest.permission#WAKE_LOCK}
- * permission to use it.</p>
- *
- * <h3>Example</h3>
- *
- * <p>A {@link WakefulBroadcastReceiver} uses the method
- * {@link WakefulBroadcastReceiver#startWakefulService startWakefulService()}
- * to start the service that does the work. This method is comparable to
- * {@link android.content.Context#startService startService()}, except that
- * the {@link WakefulBroadcastReceiver} is holding a wake lock when the service
- * starts. The intent that is passed with
- * {@link WakefulBroadcastReceiver#startWakefulService startWakefulService()}
- * holds an extra identifying the wake lock.</p>
- *
- * {@sample development/samples/Support4Demos/src/com/example/android/supportv4/content/SimpleWakefulReceiver.java complete}
- *
- * <p>The service (in this example, an {@link android.app.IntentService}) does
- * some work. When it is finished, it releases the wake lock by calling
- * {@link WakefulBroadcastReceiver#completeWakefulIntent
- * completeWakefulIntent(intent)}. The intent it passes as a parameter
- * is the same intent that the {@link WakefulBroadcastReceiver} originally
- * passed in.</p>
