Question

这是我的代码：

SpreadsheetService spreadsheet= new SpreadsheetService("v1");
    spreadsheet.setProtocolVersion(SpreadsheetService.Versions.V3);

    try {
        spreadsheet.setUserCredentials("username", "password");
        URL metafeedUrl = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");
        SpreadsheetFeed feed = spreadsheet.getFeed(metafeedUrl, SpreadsheetFeed.class);

        List<SpreadsheetEntry> spreadsheets = feed.getEntries();
        for (SpreadsheetEntry service : spreadsheets) {             
            System.out.println(service.getTitle().getPlainText());
       }
    } catch (AuthenticationException e) {           
        e.printStackTrace();
    }

但它似乎不起作用。它总是在电子表格的构造函数中崩溃。我正在使用这些库：

GDATA客户端-1.0
GDATA客户端 - 间 - 1.0
GDATA核-1.0
GDATA电子表格-3.0
GDATA电子表格 - 间 - 3.0
番石榴13.0.1

谁能告诉我可能出现的问题？

它在Spreadsheet的构造函数中崩溃了吗？不是SpreadsheetService？电子表格的实例在哪里创建？我猜，也许在幕后的某个地方。无论如何，正如一位评论者所说，用logcat检查。如果你完全不知道它崩溃的地方（它应该告诉你，如果你看到出现的文本墙），只要在任何可能的地方抛出logcat。

static final String MESSAGE = "SPREADSHEET TEST MESSAGE:";
SpreadsheetService spreadsheet= new SpreadsheetService("v1");
Log.d(MESSAGE, "spreadsheet was created successfully.");
spreadsheet.setProtocolVersion(SpreadsheetService.Versions.V3);
Log.d(MESSAGE, "setProtocolVersion done successfully.");

try {
    spreadsheet.setUserCredentials("username", "password");
    Log.d(MESSAGE, "set credentials worked.");
    URL metafeedUrl = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");
    Log.d(MESSAGE, "metafeedUrl was created successfully.");
    SpreadsheetFeed feed = spreadsheet.getFeed(metafeedUrl, SpreadsheetFeed.class);
    Log.d(MESSAGE, "feed was created, too.");
    List<SpreadsheetEntry> spreadsheets = feed.getEntries();
    Log.d(MESSAGE, "spreadsheets List was created successfully.");
    for (SpreadsheetEntry service : spreadsheets) {             
        System.out.println(service.getTitle().getPlainText());
   }
   Log.d(MESSAGE, "The for-loop worked.");
} catch (AuthenticationException e) {           
    e.printStackTrace();
}

它看起来很愚蠢，但你可以删除它工作后的所有消息。我通常只会做这种事情，如果我不知道所有正在发生的事情的名义;它应该产生比仅仅盯着屏幕更多的结果。

无论如何，看看它失败的地方并从那里弄清楚。一旦你得到更好的信息，也许可以提出一个更清晰的问题。
