wss://AutobahnAndroid | A fork of [AutoBahnAndroid project] (https://github.com/crossbario/autobahn-android) to support SSL over NIO.
WebSocket allows bidirectional real-time messaging on the Web.
Here is a simple Secure WebSocket echo client:
private final WebSocketConnection mConnection = new WebSocketConnection();
private void start() {
final String wsuri = "wss://echo.websocket.org";
try {
mConnection.connect(wsuri, new WebSocketHandler() {
@Override
public void onOpen() {
Log.d(TAG, "Status: Connected to " + wsuri);
mConnection.sendTextMessage("Hello, world!");
}
@Override
public void onTextMessage(String payload) {
Log.d(TAG, "Got echo: " + payload);
}
@Override
public void onClose(int code, String reason) {
Log.d(TAG, "Connection lost.");
}
});
} catch (WebSocketException e) {
Log.d(TAG, e.toString());
}
}... and with a custom TrustManager :
private final WebSocketConnection mConnection = new WebSocketConnection();
/**
* Trust all certificates by default; useful for self-signed certificates and testing;
* DO NOT USE FOR PRODUCTION CODE
*
* @return
*/
public final TrustManager[] createTrustAllManager() {
TrustManager[] trustAllCerts = null;
if (BuildConfig.DEBUG) {
System.err.println("*** TRUSTING ALL CERTIFICATES ***");
trustAllCerts = new TrustManager[] {
new X509TrustManager() {
public X509Certificate[] getAcceptedIssuers() {
X509Certificate[] myTrustedAnchors = new X509Certificate[0];
return myTrustedAnchors;
}
@Override
public void checkClientTrusted(X509Certificate[] certs, String authType) {
}
@Override
public void checkServerTrusted(X509Certificate[] certs, String authType) {
}
}
};
} else {
throw new RuntimeException(new CertificateException("\n\n***TRUST ALL CERTIFICATES DISABLED IN NON-DEBUG MODE ***\n\n"));
}
return trustAllCerts;
}
private void start() {
final String wsuri = "wss://echo.websocket.org";
final WebSocketSSLContext webSocketSSLContext = new WebSocketSSLContext();
try {
webSocketSSLContext.setSSLTrustManagers(createTrustAllManager());
mConnection.setWebSocketSSLContext(webSocketSSLContext);
mConnection.connect(wsuri, new WebSocketHandler() {
@Override
public void onOpen() {
Log.d(TAG, "Status: Connected to " + wsuri);
mConnection.sendTextMessage("Hello, world!");
}
@Override
public void onTextMessage(String payload) {
Log.d(TAG, "Got echo: " + payload);
}
@Override
public void onClose(int code, String reason) {
Log.d(TAG, "Connection lost.");
}
});
} catch (WebSocketException e) {
Log.d(TAG, e.toString());
}
}- Same as AndroidAutobahn
- Implements secure web sockets using SSL over pure-NIO
You can use wss://AutobahnAndroid to create native Android apps talking to WebSocket servers.
