This error is due to the user defined JAR file ( that is you have converted JAVA file into JAR file in order to import the library for your own use ) which you have compiled in the library for this application. In order to overcome this error you have to just take the JAVA file and you have give in a separate class in your package.

I had the same problem. I solved this by exporting all the drive related jars (mark with "v") in "Order and Export" tab of the build window.

I was having the same problem until a minute ago. In your app's properties make sure you are targeting an API level with Google API's. They will be listed right below the target level (4.0.3 in my case).

I was helped by the following:

  1. check Drive API in Project Properties/Java Build Path/Order and Export

    thereafter Drive API jars added to the project to lib folder

  2. uncheсk Drive API
