我使用以下客户端SSLSocketFactory代码向正在侦听的服务器发送文本，然后最终发送.wav文件，但是此代码给我带来了两个错误。
这两行给了我错误：
SSLSocketFactory socketFactory = new SSLSocketFactory(ks);
这意味着SSLSocketFactory是抽象的，不能实例化。
socketFactory.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
对此，错误是无法解析方法setHostnameVerifier，也无法解析符号ALLOW_ALL_HOSTNAME_VERIFIER。
整个代码：
Button send;
EditText textSend;
private String ip_address = "192.168.10.103";
private int port = 5000;
private SSLSocket socket = null;
private BufferedWriter out = null;
private BufferedReader in = null;
private final String TAG = "TAG";
private char keystorepass[] = "....".toCharArray();
private char keypassword[] = "....".toCharArray();

以上两个问题我已经修复，但我有这个错误输出：
FATAL EXCEPTION: main

android.os.NetworkOnMainThreadException

SSLSocketFactory是抽象的，因此您必须使用它的一个子级。您可以使用SSLSocketFactory.getDefault()来获得默认实现。
CCD_ 8是CCD_ 9而非CCD_。您应该在代码的那部分使用它。
如果您没有使用HttpsURLConnection，您可以也应该验证如下URL：
// Open SSLSocket directly to gmail.com
SocketFactory sf = SSLSocketFactory.getDefault();
SSLSocket socket = (SSLSocket) sf.createSocket("gmail.com", 443);
HostnameVerifier hv = HttpsURLConnection.getDefaultHostnameVerifier();
SSLSession s = socket.getSession();
// Verify that the certicate hostname is for mail.google.com
// This is due to lack of SNI support in the current SSLSocket.
if (!hv.verify("mail.google.com", s)) {
throw new SSLHandshakeException("Expected mail.google.com, "
"found " + s.getPeerPrincipal());
}
// At this point SSLSocket performed certificate verificaiton and
// we have performed hostname verification, so it is safe to proceed.
// ... use socket ...
socket.close();
你可以在Android文档中看到一些真实世界的例子：

您要么刚刚发明了构造函数new SSLSocketFactory(KeyStore)和方法SSSLSocketFactory.setHostnameVerifier()，要么导入了错误的SSLSocketFactory。
