WearListenerService onDataChanged seltsames Verhalten

Question

Ich möchte bidirektionale Datenübertragung zwischen Android Wear und Handheld machen. Alles scheint gut zu sein, außer onDataChanged auf Handheld auszulösen. Es löst nur dann aus, wenn ich ein USB-Kabel anschließe, das an den PC angeschlossen ist. Also ich verstehe nicht, warum es passiert ist.

Hier ist mein Code:

Hauptaktivitäten sowohl auf Handheld und tragen Sie einfach Dienste starten. Datenpfad ist: 1) Tragen Sie den Service, um Daten zu senden. onDataChanged on wear ausgelöst, wie es sollte 2) Handheld Trigger onDataChanged nur nach dem Abstecken oder stecken USB-Kabel. Handheld sendet Daten zum Tragen. 3) onDataChanged Trigger auf Verschleiß wie es sollte und Daten empfangen.

Answer 1

Per der Google Play services 8.3 blog post:

Mit Google Play-Dienste 8.3 haben wir die DataApi aktualisiert Dringlichkeit, wie Datenelemente zu ermöglichen, werden synchronisiert. Jetzt kann dem Datenelement eine Priorität hinzugefügt werden, um festzustellen, wann es synchronisiert werden sollte.Wenn Sie z. B. eine App erstellen, die eine sofortige Synchronisierung erfordert, z. B. eine Fernsteuerungs-App, können Sie dies dennoch sofort tun, indem Sie setUrgent() aufrufen. Bei einer Aktualisierung Ihrer Kontakte können Sie jedoch Verzögerungen tolerieren. Nicht dringende Datenelemente können sich um bis zu 30 Minuten verzögern, aber Sie können davon ausgehen, dass sie in den meisten Fällen innerhalb weniger Minuten zugestellt werden. Niedrige Priorität ist jetzt der Standardwert, daher wird setUrgent() benötigt, um das vorherige Timing zu erhalten.

So stellen Sie sicher, dass Sie setUrgent() auf Ihre Datenanforderungen aufrufen, wenn Sie möchten, dass sie sofort mit anderen verbundenen Geräten synchronisiert werden.
