android - 来自 code.samsung.com 的示例 Android XMPP 在连接时给出 KeyStoreException 和 NoSuchAlgorithmException

Question

我对 XMPP 和 Connection 还很陌生。我从 code.samsung.com 下载了一个虚拟代码并尝试运行该代码。但是它在 LogCat 中给出了 java.security.KeystoreException 和 java.security.nosuchalgorithmexception 和 无法连接到 mitesh @gmail.com

我的代码是，

代码有什么问题？请帮助..!!

我不知道三星为什么推荐过时的、不再维护的 aSmack 版本。这种错误通常是由错误的 TrustStore 配置引起的。

我建议你试试 aSmack fork that is maintained.还要确保阅读自述文件并按照说明进行操作。否则你会遇到麻烦。
