Das Problem könnte aus einer der Bibliotheken kommt Ihre Anwendung abhängt, eine Bibliothek, die sich abhängig von Google Play Dienstleistungen auch. Möglicherweise verwenden Sie eine ältere Version des Google Play Services SDK und es basiert immer noch auf der Tatsache, dass Google API Client Klasse eine Schnittstelle ist. Dies bricht die Abwärtskompatibilität aufgrund der transitiven Abhängigkeiten von Bibliotheken. Bitte überprüfen Sie, ob Sie die neueste Version verwenden oder entfernen Sie die Abhängigkeiten wenn möglich.
