Question

应用程序应该在第一次启动时对用户进行身份验证（如果第一次尝试失败，则应在未来启动时）。身份验证逻辑封装在AsyncTask中，并通过以下方法实现（用户帐户和范围有效）：

private String fetchToken() throws IOException {
    try {
        return GoogleAuthUtil.getToken(mParentActivity, mUserEmail, mScope);
    } catch (UserRecoverableAuthException userRecoverableException) {
        if (!secondTry) {
            secondTry = true;
            mParentActivity.handleException(userRecoverableException);
        }
    } catch (GoogleAuthException fatalException) {
        fatalException.printStackTrace();
        mParentActivity.handleException(fatalException);
    }
    return null;
}

handleException方法：

public void handleException(final Exception e) {
    runOnUiThread(new Runnable() {

        @Override
        public void run() {
            if (e instanceof GooglePlayServicesAvailabilityException) {
                int statusCode = ((GooglePlayServicesAvailabilityException) e).getConnectionStatusCode();
                Dialog dialog = GooglePlayServicesUtil.getErrorDialog(statusCode, MainActivity.this,
                        REQUEST_CODE_RECOVER_FROM_PLAY_SERVICES_ERROR);
                dialog.show();
            } else if (e instanceof UserRecoverableAuthException) {
                Intent intent = ((UserRecoverableAuthException) e).getIntent();
                startActivityForResult(intent, REQUEST_CODE_RECOVER_FROM_AUTH_ERROR);
            } else if (e instanceof GoogleAuthException) {
                showToast("Fatal error during authentication");
            }
        }
    });
}

在不同设备上测试此代码表明没有严格的模式来检测错误原因。症状是：

多个登录活动显示在彼此之上，但没有一个成功：
即使我设置UserRecoverableAuthException标志以防止它，也会抛出多个secondTry;

此外，在LogCat中发现以下例外情况：

有没有人有什么建议导致这个问题？

无法通过GoogleAuthUtil.getToken（）进行身份验证
