我正在使用 koush 开发的 AndroidSync 库来创建 WebSocket(服务器/客户端)并在两个 Android 设备之间传输数据。这两个设备通过 Wi-Fi 连接(一个是 Wi-Fi AP,另一个连接到它)。在发送请求后,客户端设备会在 4-5 秒后出现 TimeoutException 异常。
以下是我迄今为止所做的工作: ServerActivity.java
这是我在客户端设备的logcat中获取到的内容。
以下是我迄今为止所做的工作: ServerActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_server);
mSockets = new ArrayList<WebSocket>();
mAsyncHttpServer = new AsyncHttpServer();
mWebSocketCallback = new AsyncHttpServer.WebSocketRequestCallback() {
@Override
public void onConnected(final WebSocket webSocket, RequestHeaders headers) {
mSockets.add(webSocket);
webSocket.send("Welcome Client");
webSocket.setClosedCallback(new CompletedCallback() {
@Override
public void onCompleted(Exception ex) {
try {
if (ex != null)
Log.e("WebSocket", "Error");
} finally {
mSockets.remove(webSocket);
}
}
});
webSocket.setStringCallback(new WebSocket.StringCallback() {
@Override
public void onStringAvailable(String s) {
Log.d("SERVERTAG",s);
Toast.makeText(getApplicationContext(),s,Toast.LENGTH_SHORT).show();
}
});
}
};
mAsyncHttpServer.websocket("/",mWebSocketCallback);
mAsyncHttpServer.listen(Utils.PORT_NUMBER);
Button sendButton = (Button) findViewById(R.id.sendButtonS);
sendButton.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view) {
for(WebSocket socket : mSockets) {
socket.send("Server sent a string");
}
}
});
}
ClientActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_client);
mWifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
//Resolve IP address
int ipAddress = mWifiManager.getConnectionInfo().getIpAddress();
String hostAddress = Formatter.formatIpAddress(ipAddress);
hostAddress = "http://" + hostAddress + ":" +Utils.PORT_NUMBER;
Log.d("CLIENTTAG", "address is " + hostAddress);
mWebSocketConnectCallback = new AsyncHttpClient.WebSocketConnectCallback() {
@Override
public void onCompleted(Exception ex, WebSocket webSocket) {
if (ex != null) {
ex.printStackTrace();
return;
}
webSocket.send("Hello Server");
webSocket.setStringCallback(new WebSocket.StringCallback() {
@Override
public void onStringAvailable(String s) {
Log.d("CLIENTTAG",s);
Toast.makeText(getApplicationContext(), s, Toast.LENGTH_SHORT).show();
}
});
}
};
mAsyncHttpClient = AsyncHttpClient.getDefaultInstance();
mAsyncHttpClient.websocket(hostAddress, null, mWebSocketConnectCallback);
}

我之前没有做过套接字编程。请有经验的人帮助一下我吗?
非常感谢任何帮助。
