如何将url中的阿拉伯语文本作为参数从android app发送到php webservice

Question

I want to add search function in my android app, but the problem is when i add arabic parameter to url e.g("example.com?q=بلد") it gives null result. although if i add text manually in browser to url it works fine.

        InputStream inputStream = null;
        String contentAsString = null;
        try {
            URL url = new URL("example.com?q=بلد");
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.connect();
            inputStream = conn.getInputStream();
            contentAsString = readIt(inputStream);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (inputStream != null) {
                try {
                    inputStream.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }

PHP code

    header('Content-Type: text/html; charset=utf-8');

    mysql_select_db($this->get_databaseName(), $this->con);
    mysql_query("SET NAMES 'utf8'");
    mysql_query('SET CHARACTER SET utf8');

    $query="Select * from tbl_posts where post_title=".$_GET['q']";

Data base table field encoding method is utf8_general_ci

In simple words i want to add some arabic text as parameter in url, through which i can query database using php web service.

While sending such kind of special characters to server you need to encode such input with the help of URLEncoder.encode(your_input, "utf-8") and while receiving such kind of data first of all you need to decode it with the help of URLDecoder.decode(your_data, "utf-8")
