我有一個從服務器接收的Google Drive訪問令牌。收到我之後，嘗試使用此令牌初始化GoogleCredential，然後對Drive API執行請求。但是，當我嘗試執行請求我趕上一個堆棧跟蹤：Android GoogleCredential無效憑據

還有就是我如何初始化憑據，並執行請求驅動：
private void initClient() {
JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
HttpTransport transport = AndroidHttp.newCompatibleTransport();
try {
GoogleClientSecrets googleClientSecrets = loadClientSecretsResource(mContext, jsonFactory);
GoogleCredential credential = new GoogleCredential.Builder()
.setClientSecrets(googleClientSecrets)
.setJsonFactory(jsonFactory)
.setTransport(transport)
.build();
credential.setAccessToken(AppPreferences.Storage.GoogleDrive.getToken(mContext));
credential.refreshToken();
mService = new Drive.Builder(transport, jsonFactory, credential)
.setApplicationName(mContext.getResources().getString(R.string.app_name))
.build();
addCloud();
} catch (IOException e) {
e.printStackTrace();
}
}
private void addCloud() {
Map<String, Long> quotaInfo = getQuotaInfo();
CloudStorageCollector.saveCloudToDatabase(AppPreferences.Storage.GoogleDrive.getToken(mContext), BaseVault.VaultCode.GoogleDriveVault,
quotaInfo.get(StoragesHelper.USED_QUOTA_KEY), quotaInfo.get(StoragesHelper.TOTAL_QUOTA_KEY));
}
public Map<String, Long> getQuotaInfo() {
if (mService == null) return null;
Map<String, Long> quotaInfo = new HashMap<>();
try {
About about = mService.about().get().execute();
quotaInfo.put(StoragesHelper.USED_QUOTA_KEY, about.getQuotaBytesUsed());
quotaInfo.put(StoragesHelper.TOTAL_QUOTA_KEY, about.getQuotaBytesTotal());
return quotaInfo;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
在getQuotaInfo方法我捕捉到了異常。我究竟做錯了什麼？
