title: How do I connect Android apps with Google Sheets spreadsheets?
body: <p>I'm trying to do an Android app that needs to work with Google spreadsheet API. I'm new in this, so I'm starting with the version 3 of the api: <a href="https://developers.google.com/google-apps/spreadsheets/" rel="noreferrer">https://developers.google.com/google-apps/spreadsheets/</a>  </p>
  
  <p>I followed all the steps, downloaded all the jar files to <code>lib</code> subfolder in my project folder and then I added to the build path in Eclipse as usual. So although there is no Java example to perform Oauth 2.0, I just tried to declare:</p>
  
  <pre><code>SpreadsheetService service = new SpreadsheetService("v1");
  </code></pre>
  
  <p>but when I emulate this simple line it gives me an error:</p>
  
  <pre><code>java.lang.NoClassDefFoundError: com.google.gdata.client.spreadsheet.SpreadsheetService
  </code></pre>
  
  <p>I'm using all the jars included in the documentation and I have the import:</p>
  
  <pre><code>import com.google.gdata.client.spreadsheet.SpreadsheetService;
  </code></pre>
  
  <p>but I am totally lost. I dont know what else to do just to start, connect to Google APIs and work with the spreadsheets. </p>
