Android上的Google Spreadsheet API無效令牌

Question

我試圖創建一個Android應用程序，它在谷歌驅動器上創建一個電子表格，然後將數據保存到它。驅動器部分工作正常，但由於某種原因，當我嘗試使用我的谷歌驅動器的認證，大概電子表格API（範圍https://spreadsheets.google.com/feeds/「與電子表格api我得到」com.google.gdata.util.AuthenticationException：令牌無效「

這裏是我的相關代碼

private static final String[] SCOPES = { DriveScopes.DRIVE, "https://spreadsheets.google.com/feeds/" }; 

    credential = GoogleAccountCredential.usingOAuth2(
      getApplicationContext(), Arrays.asList(SCOPES)) 
      .setBackOff(new ExponentialBackOff()) 
      .setSelectedAccountName(googleUserName); 

    driveService = new com.google.api.services.drive.Drive.Builder(
      transport, jsonFactory, credential) 
      .setApplicationName(getString(R.string.app_name)) 
      .build(); 

    //Calls to driveService work as expected 
    //But this returns the invalid token exception 
    SpreadSheetService service = new SpreadsheetService("AppSheetservice"); 

    final URL SPREADSHEET_FEED_URL = new URL(
      "https://spreadsheets.google.com/feeds/spreadsheets/private/full"); 

    service.setUserToken(saleActivity.credential.getToken()); 
    //This line throws the invalid token error 
    feed = service.getFeed(SPREADSHEET_FEED_URL, SpreadsheetFeed.class); 

Answer 1

我終於想通了這個問題是你需要調用

service.setAuthSubToken(credential.getToken()); 

，而不是

service.setUserToken(credential.getToken());
