Java.lang.NoClassDefFoundError: com.google.api.services.drive.Drive

When trying to use any function of a disk class:

Drive service = new Drive.Builder(AndroidHttp.newCompatibleTransport(),new GsonFactory(), credential).build();

I have included the right jar in the libs folders:

Google-API-Services-disk-v2-rev123-1.18.0-rc.jar

and import is ok:

import com.google.api.services.drive.Drive; Import com.google.api.services.drive.DriveScopes;

But he continues to show an error:

I believe that you did not include the google-api-client-1.18.0-rc.jar , which is why you get the exception.

Once you download and unzip the Drive API library , read drive/readme.html . He listed the dependent jars for google-api-services-drive-v2-rev123-1.18.0-rc.jar that he needed to enable. Dependent banks may be located in the drive/libs folder.

Below is a complete set of banners that must be included in the Android application:

  • Google-API-Services-disk-v2-rev123-1.18.0-rc.jar
  • Google-api-client-1.18.0-rc.jar
  • Google-OAuth-client-1.18.0-rc.jar
  • Google-client-client-1.18.0-rc.jar
  • jsr305-1.3.9.jar
  • Google-client-client-gson-1.18.0-rc.jar
  • Google-api-client-android-1.18.0-rc.jar
  • Google-http-client-android-1.18.0-rc.jar
