好吧，我尝试使用 Account Manager 并收到“401 Token Invalid”错误。可能是什么原因。
调试日志
Account name = xxxxxx@gmail.com
Token is : DQAAALIAAAAh-xxxxxxx
Starting Google DATA API loader-----------------
Inside Google Notebook loader-----------------
Setting Token : DQAAALIAAAAh-xxxxx
Url is : https://docs.google.com/feeds/default/private/full
Exception getting docs feed : 401 Token invalid
Done Google DATA API loader-----------------
示例代码：
Log.d("Main","\tInside GoogleDATA API -----------------");
HttpTransport transport = new NetHttpTransport();
GoogleHeaders headers = new GoogleHeaders();
Log.d("Main","\tSetting Token : " + authToken);
headers.setGoogleLogin(authToken);
headers.gdataVersion="3.0";
transport.defaultHeaders = headers;
AtomParser parser = new AtomParser();
parser.namespaceDictionary = Namespace.DICTIONARY;
transport.addParser(parser);
try {
DocsUrl url = DocsUrl.forDefaultPrivateFull();
DocumentListFeed feed = DocumentListFeed.executeGet(transport,url);
List<DocumentListEntry> docs = feed.docs;
Log.d("Main","\tDocs count = " + docs.size());
for (Iterator iterator = docs.iterator(); iterator.hasNext();) {
DocumentListEntry documentListEntry = (DocumentListEntry) iterator
.next();
Log.d("Main","\t\tDocument title is : " + documentListEntry.title);
}
} catch (IOException e) {
Log.d("Main","Exception getting docs feed : " + e.getMessage());
//handleException(e);
}
Log.d("Main","\tDone GoogleDATA API -----------------");
