本文详细介绍了在Android设备上遇到的SNTP时间同步失败问题，主要原因是无法连接到Google的时间服务器。通过修改config_ntpServer配置，将时间服务器更改为苹果的time1.apple.com，成功解决了这一问题。

找到报错的地方：
frameworks\base\core\ java\android\net\SntpClient.java

/**
 * Sends an SNTP request to the given host and processes the response.
 *
 * @param host host name of the server.
 * @param timeout network timeout in milliseconds.
 * @param network network over which to send the request.
 * @return true if the transaction was successful.
 */
public boolean requestTime(String host, int timeout, Network network) {
    final Network networkForResolv = network.getPrivateDnsBypassingCopy();
    InetAddress address = null;
    try {
        address = networkForResolv.getByName(host);
    } catch (Exception e) {
        EventLogTags.writeNtpFailure(host, e.toString());
        if (DBG) Log.d(TAG, "request time failed: " + e);
        return false;
    }
    return requestTime(address, NTP_PORT, timeout, networkForResolv);
}

发现时间服务器出错。

修改：
\frameworks\base\core\res\res\values\config.xml
