android-service-binding

问题 I am reading upon Android Bound service, http://developer.android.com/guide/components/bound-services.html public class LocalService extends Service { // Binder given to clients private final IBinder mBinder = new LocalBinder(); // Random number generator private final Random mGenerator = new Random(); /** * Class used for the client Binder. Because we know this service always * runs in the same process as its clients, we don't need to deal with IPC. */ public class LocalBinder extends Binder

问题 I would like to access notifications on a Android phone by using the NotificationListenerService. I checked lots of tutorials but I can't find where they call the service. Should I use bindService or startService on MainActivity? How should the intents look like? Can someone show me the syntax of this? Check out one of the service implementations I am studying: public class NLService extends NotificationListenerService { Context context; @Override public void onCreate() { super.onCreate();

问题 I have a service that is started. In addition, other components can bind to the service. When a component binds to the service, it has new parameters it needs to deliver to the service. Is it possible to force onBind to be called each time a caller needs to bind (so as to deliver new data through intent)? And if so, is the additional overhead of calling onBind each time significant? BTW, this is a local service where I extend Binder instead of using Messenger. 回答1: Few points to consider: 1)

问题 I have a service in Android that encapsulates a framework that has a start method. The service boils down to something like this, many things omitted: public class MyService extends Service { private IBinder thisBinder; public MyService(){ thisBinder = new LocalBinder(); } @Override public IBinder onBind(Intent intent) { return thisBinder; } public void start(Map<String, Object> options) { getDriverManager().start(options); } } I also have a bridging class that makes calls to the service:

问题 I'm surprisingly struggling to get hold of the instance of a service which is derived from MediaBrowserServiceCompat . For a typical service, to achieve that, a local binder is used class MyService extends MediaBrowserServiceCompat { class MyBinder extends Binder { public MyService getService() { return MyService.this; } private final MyBinder binder = new MyBinder(); @Override public IBinder onBind(Intent intent) { return binder; } public void doMagic() { // <-- How to call this from

问题 I have created a system service that communicates with a zigbee device. Updated APIs and created system.img and flashed on the device and made custom SDK for android programming. In the Mainactivity class, try { ZigbeeManager zm = (ZigbeeManager) getSystemService(Context.ZIGBEE_SERVICE); zm.write("Hello World!\r"); } catch (Exception ex) { Log.d(TAG, "Error in Zigbee Service: " + ex.toString()); } I am getting an error over the words "Context.ZIGBEE_SERVICE". It says "Must be one of : list of

问题 I am creating a small app using Mosby. The app has a service which I want to bind to. I guess the correct place to do this is in the presenter. But I can't really figure out how to do it. What I want to archive is when the service is bound I want to call a method on it and push that value to the view, so that the state right now is correct. When the service sends updates on the event bus I want to push that to the view as well. I have found some example on the later part, but nothing about
