211 <p>As a printer OEM, you can use the {@link android.printservice} framework to provide interoperability with your printers from Android devices. You can build and distribute print services as APKs, which users can install on their devices . A print service app operates primarily as a headless service by subclassing the {@link android.printservice.PrintService} class, which receives print jobs from the system and communicates the jobs to its printers using the appropriate protocols.</p>
245 <p>If you want to emulate an NFC card that is using these protocols in your app, create a service component based on the {@link android.nfc.cardemulation.HostApduService} class. Whereas if your app instead uses a secure element for card emulation, you need to create a service
315 <p>To build a remote controller, you can implement your user interface any way you want to, but to deliver the media button events to the user's media app you must create a service that extends the {@link android.service.notification.NotificationListenerService} class and implements the {@link android.media.RemoteController.OnClientUpdateListener} interface. Using the {@link android.service.notification.NotificationListenerService} as the basis is important because it provides the appropriate privacy restrictions, which require users to enable your app as a notification listener within the system security settings.</p>
317 <p>The {@link android.service.notification.NotificationListenerService} class includes a couple abstract methods you must implement, but if you are only concerned with the media controller events for handling media playback, you can leave your implementation for those empty and instead focus on the {@link android.media.RemoteController.OnClientUpdateListener} methods.</p>
411 <p>If you're developing an app that provides storage services for files (such as a cloud save service), you can participate in this unified UI for picking files by implementing a content provider as a subclass of the new {@link android.provider.DocumentsProvider} class. Your subclass of {@link android.provider.DocumentsProvider} must include an intent filter that accepts the {@link android.provider.DocumentsContract#PROVIDER_INTERFACE} action (<code>"android.content.action.DOCUMENTS_PROVIDER"</code>). You must then implement the four abstract methods in the {@link android.provider.DocumentsProvider}:</p>
477 <p>However, be aware that the sensor will deliver your app the batched events based on your report latency <strong>only while the CPU is awake</strong>. Although a hardware sensor that supports batching will continue to collect sensor events while the CPU is asleep, it will not wake the CPU to deliver your app the batched events. When the sensor eventually runs out of its memory for events, it will begin dropping the oldest events in order to save the newest events. You can avoid losing events by waking the device before the sensor fills its memory then call {@link android.hardware.SensorManager#flush flush()} to capture the latest batch of events. To estimate when the memory will be full and should be flushed, call {@link android.hardware.Sensor#getFifoReservedEventCount()} to get the maximum number of sensor events it can save, and divide that number by the rate at which your app desires each event. Use that calculation to set wake alarms with {@link android.app.AlarmManager} that invoke your {@link android.app.Service} (which implements the {@link android.hardware.SensorEventListener}) to flush the sensor. It's okay that the alarm may execute even while the device is awake, because the alarm interval should be large enough that it occurs only a few times in a day.</p>
509 <p>Android 4.3 added the {@link android.service.notification.NotificationListenerService} APIs, allowing apps to receive information about new notifications as they are posted by the system. In Android 4.4, notification listeners can retrieve additional metadata for the notification and complete details about the notification's actions:</p>
522 <p>Apps that provide an <a href="{@docRoot}guide/topics/ui/accessibility/services.html">accessibility service</a> can now also enhance their capabilities with new APIs that provide information about view collections such as list or grid views using {@link android.view.accessibility.AccessibilityNodeInfo.CollectionInfo} and {@link android.view.accessibility.AccessibilityNodeInfo.CollectionItemInfo}.</p>
