Send Text From Android To Pc Via Wi-fi Connection

I'm new to android programming and stackoverflow. I want to create an app that sends some info (like a text) to a PC on the same network (Wi-fi) and read on the PC using a Java app

Solution 1:

You should use wi-fi manager in client and server programs and set wifi direct between PC and Android.

For the permissions use this:

<uses-permissionandroid:name="android.permission.ACCESS_WIFI_STATE" /><uses-permissionandroid:name="android.permission.INTERNET" />

In server use :

ServerSocketserverSocket=newServerSocket(9000);
Socketsocket= serverSocket.accept();

And in client :

socket = newSocket()
socket.connect("192.168.49.(Server Device wi-fi IP(zero to 255))" , 9000);

Then use these methods in both programs for send-receive data

DataOutputStreamoutputStream=newDataOutputStream(socket.getOutputStream());
BufferedReaderinputStream=newBufferedReader(newInputStreamReader(socket.getInputStream()));

//in serverStringtxt="Hello from Server to Client\n";           
outputStream.write(txt.getBytes());

//in client Stringmessage= inputStream.readLine();

socket.close();

Server sends the text and client checks the input stream for a '\n' in it.

Solution 2:

As user5001333 said, you must build a server-client pattern using sockets, for example.

In Android you can't perform network operations on the main thread so you have to create a background thread (like asynctask) which establish the connection between you (client) and the pc (server).
