Implémentation de NotificationListenerService

J'essaie d'implémenter NotificationListnerService qui est ajouté dans Android 4.3 mais je ne suis pas en mesure d'obtenir les détails de la notification.

Mon code est comme ci-dessous

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
        mBuilder.setSmallIcon(R.drawable.ic_launcher);
        mBuilder.setContentTitle("notification test");
        mBuilder.setContentText("Notification text");
        mBuilder.setAutoCancel(true);
        Intent resultIntent = new Intent(this, ResultActivity.class);
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        // Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack(ResultActivity.class);
        // Adds the Intent that starts the Activity to the top of the stack
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(
                    0,
                    PendingIntent.FLAG_UPDATE_CURRENT
                );
        mBuilder.setContentIntent(resultPendingIntent);
        NotificationManager manager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
        manager.notify(1, mBuilder.build());
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

public class NotificationListenerTesting extends NotificationListenerService{

    public static String TAG = "NotificationListenerTesting";
    //private StatusBarNotification[] mStatusBarNotification;

    @Override
    public void onCreate(){
        super.onCreate();
        Log.d(TAG, "Inside on create");
    }
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {
        TAG = "onNotificationPosted";
        Log.d(TAG, "id = " + sbn.getId() + "Package Name" + sbn.getPackageName() + 
                "Post time = " + sbn.getPostTime() + "Tag = " + sbn.getTag());
    }
    @Override
    public void onNotificationRemoved(StatusBarNotification sbn) {
        TAG = "onNotificationRemoved";
        Log.d(TAG, "id = " + sbn.getId() + "Package Name" + sbn.getPackageName() + 
                "Post time = " + sbn.getPostTime() + "Tag = " + sbn.getTag());

    }

}

Le fichier manifeste Android est

            </intent-filter>
        </service>
    </application>
</manifest>

mais après la notification, cliquez sur ou sur le message de notification NotificationListenerService n'est pas appelé, qu'est-ce qui ne va pas ou ai-je raté quelque chose? Comment l'implémenter?

À l'intérieur du NotificationListenerService, vous avez besoin d'un boucleur pour communiquer avec le thread GUI afin de pouvoir créer une diffusion pour gérer l'interaction GUI.

Hope this exemple vous aidera.

Vous devez accorder l'accès à votre application pour lire les notifications: "Paramètres> Sécurité> Accès aux notifications" et vérifier votre application.

Au moins un problème avec votre code est que votre implémentation de onBind ()

Il n'est pas nécessaire de remplacer cette méthode. Mais si vous le devez, retournez au moins l'IBinder retourné par la superclasse.

@Override
public IBinder onBind(Intent intent) {
    return super.onBind(intent);
}

Il pourrait être un peu tard. Mais il y a quelques mois, j'ai également eu du mal à faire fonctionner NotificationListenerService.

Depuis lors, j'ai appris à l'implémenter et j'ai eu envie de créer un tutoriel d'implémentation pour aider ceux qui ont vécu la même chose que moi

Si quelqu'un est intéressé, consultez le projet ici: https://github.com/Chagall/notification-listener-service-example

J'espère que cela aide quelqu'un qui se débat avec.

Je sais qu'il est trop tard pour répondre à la question, mais comme je n'ai pas pu trouver Paramètres> Son et notifications -> Accès aux notifications, j'autorise directement l'accès aux notifications à mon application en tirant cette intention:

startActivity (nouvelle intention (Settings.ACTION_NOTIFICATION_LISTENER_SETTINGS));

J'ai rencontré le même problème et j'ai trouvé des indices pour cela.

NotificationListenerService peut ne pas fonctionner sauf si vous appelez bindService() pour le démarrer.

Parfois, il a démarré automatiquement lorsque vous avez activé "Accès aux notifications" et parfois ce n'est pas le cas.

La notification que vous créez n'a pas de "tickerText". J'ai constaté que si la notification n'a pas tickerText, onNotificationPosted n'est pas appelé.

Dans votre code, ajoutez mBuilder.setTicker ("votre texte ici").

onNotificationPosted devrait maintenant être appelé en supposant que le reste de la configuration de NotificationListenerService est copacétique.

Je fais la même chose que dans GitHub, mais je ne vais toujours pas dans la classe de notification.
