Decoding Characters In Android

I am working on my android project. I have to send some words to the server application via my android application. After I send them, I will able to search some surveys and return

Solution 1:

short answer

use UTF-8 encoding

---

If you have a

Stringmessage= ...;

this is converted to a byte[]

byte[] bytes = message.getBytes();

then the DatagramPacket must be constructed using

new DatagramPacket(bytes, bytes.length(), ... );

Your call uses

new DatagramPacket( message.getBytes, message.length(),..,

but this uses the String length but Farsi requires more than one byte per character.

The string فارسی has 5 characters, but the UTF-8 encoding requires 10 bytes. You need to send 10 bytes.One letter of your alphabet in UTF-8 encoding requires 2 bytes, so this word with 5 letters is encoded in 10 bytes. Datagram packet lengths must be given in byte counts.

update

Having parameters set as:

Stringparameters="parameter1=" + URLEncoder.encode("YOUR_STRING_TO_ENCODE","UTF-8");

then, under an AsyncTask:

HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setRequestMethod("POST");
conn.setFixedLengthStreamingMode(params.getBytes().length);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

PrintWriter out = new PrintWriter(conn.getOutputStream());
out.print(params);
out.close();

String response = "";
Scanner inStream = new Scanner(conn.getInputStream());

while (inStream.hasNextLine()) {
    response += (inStream.nextLine());
}

Then, with this, you will got the result from server:
