What do you mean? Android blocks apps from binding to ports which is what apache httpd does unless you root. I would be asking Claude for an exploit to unlock t

  Not if the application has the right permissions on their installation manifest. <uses-permission android:name="android.permission.INTERNET" /> Then you need to write the server handling code on a background application thread, with perfectly working server sockets. This only works on wlan, or local network when using bluethooth, but who wants data modem for a server anyway. With Gemini's compliment, import kotlinx.coroutines.Dispatchers import kotlinx.coroutines.withContext import java.io.BufferedReader import java.io.InputStreamReader import java.net.ServerSocket import java.net.Socket import java.net.SocketException class AndroidTcpServer { private var serverSocket: ServerSocket? = null private var isRunning = false // Call this function from a CoroutineScope (e.g., lifecycleScope.launch) async suspend fun startServer(port: Int = 8080) { withContext(Dispatchers.IO) { try { serverSocket = ServerSocket(port) isRunning = true // Loop to continuously accept incoming client connections while (isRunning) { val clientSocket = serverSocket?.accept() // Blocks until a client connects if (clientSocket != null) { // Handle each client connection in a separate background routine handleClient(clientSocket) } } } catch (e: SocketException) { // Triggered when stopServer() closes the socket println("Server socket closed: ${e.message}") } catch (e: Exception) { e.printStackTrace() } finally { stopServer() } } } private suspend fun handleClient(socket: Socket) { withContext(Dispatchers.IO) { try { val reader = BufferedReader(InputStreamReader(socket.getInputStream())) val outputStream = socket.getOutputStream() // Read incoming text from client val incomingMessage = reader.readLine() println("Received from client: $incomingMessage") // Send a simple response back to the client val response = "Hello from Android Server!\n" outputStream.write(response.toByteArray()) outputStream.flush() } catch (e: Exception) { e.printStackTrace() } finally { // Always close individual client connections socket.close() } } } fun stopServer() { isRunning = false try { serverSocket?.close() } catch (e: Exception) { e.printStackTrace() } } } As you might imagine by my comment history, I am a big fan of letting Android be Android, with Android native apps, not stuffing GNU/Linux into an APK.
