Ich entwickle und Android-Anwendung, die einen Rundfunkempfänger hat eingehende SMS von einer bestimmten Anzahl zu übertragen. Wenn die Nachricht von dieser Nummer stammt und in einem bestimmten Format vorliegt, antwortet die Anwendung mit der aktuellen Länge und Breite des Benutzers. AberFusedLocationApi gibt null zurück
, wenn die Antwortnachricht erzeugt wird, die Lage wird null always.I ist mit GoogleApiClient Objekt und FusedLocationApi.
mLastLocation = LocationServices.FusedLocationApi.getLastLocation (googleAPIClient);
immer null zurück und meine Botschaft enthält an den Orten der Längen- und Breitengrad null-Werte. Hier ist der Dienst, der vom Broadcast-Empfänger angerufen wird, wenn eine Nachricht eingeht und nach dem Standort fragt.
