Ich möchte eine Datei / ein Bild mit der Google Play Services-Bibliothek auf Google Drive hochladen (ohne Verwendung von JAR-Dateien).

Dies ist mit der Android-API von Google Drive möglich

Google Drive Android API

Ich verwende ein Schnellstart-Projekt von Github: -

Aber ich stecke in der Google Play Services-Bibliothek fest (aufgrund von DriveApi.DriveContentsResult): -

import com.google.android.gms.drive.DriveApi.DriveContentsResult;

Errors sind: -
