我对XMPP和Connection的东西很陌生。我已经从 code.samsung.com 下载了一个虚拟代码并尝试运行该代码。但它在LogCat中给予例外，java.security.KeystoreException和java.security.nosuchalgorithmexception和can't connect to mitesh@gmail.com
我的代码是，

代码有什么问题？请帮忙..！！
我不知道
为什么三星推荐一个过时的，不再维护的aSmack版本。此类错误通常是由错误的信任库配置引起的。
我建议你尝试一个维护的aSmack叉子。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。
下面是一个代码片段，可用于避免密钥库异常和您描述的算法异常：
XMPPConnection xmppCon;
ConnectionConfiguration conf;
SASLAuthentication.registerSASLMechanism("DIGEST-MD5", SASLDigestMD5Mechanism.class);
SASLAuthentication.supportSASLMechanism("DIGEST-MD5", 0);
conf = new ConnectionConfiguration(HOST, PORT);//, SERVICE);
conf.setDebuggerEnabled(true);
conf.setSASLAuthenticationEnabled(true);
conf.setCompressionEnabled(true);
conf.setSecurityMode(SecurityMode.enabled);
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH){
conf.setTruststoreType("AndroidCAStore");
conf.setTruststorePassword(null);
conf.setTruststorePath(null);
}else{
conf.setTruststoreType("BKS");
String path = System.getProperty("javax.net.ssl.trustStore");
if(path == null){
path = System.getProperty("java.home") + File.separator + "etc" + File.separator + "security" + File.separator + "cacerts.bks";
}
conf.setTruststorePath(path);
}
xmppCon = new XMPPConnection(conf);
你用错了asmack。使用好友云 2011。
