Question

My question is about the script below:

I saw this question ByetHost server passing html values "Checking your browser" with JSON String at StackOverflow, but I don't know how can I change my java. Please help me. I use free vistapanel.

php

<?php

 if($_SERVER['REQUEST_METHOD']=='POST'){
 
 $image = $_POST['image'];
 
 require_once('UploadToServer.php');
 
 $sql = "INSERT INTO images  VALUES (?)";
 
 $stmt = mysqli_prepare($con,$sql);
 
 mysqli_stmt_bind_param($stmt,"s",$image);
 mysqli_stmt_execute($stmt);
 
 $check = mysqli_stmt_affected_rows($stmt);
 
 if($check == 1){
 echo "Image Uploaded Successfully";

 }else{
 echo "Error Uploading Image";

 }
 mysqli_close($con);
 
 }else{
 echo "Error";

 }
 exit();
 ?>

Here is my android

public class RequestHandler {

    public String sendGetRequest(String uri) {
        try {
            URL url = new URL(uri);
            HttpURLConnection con = (HttpURLConnection) url.openConnection();
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(con.getInputStream()));

            String result;

            StringBuilder sb = new StringBuilder();

            while((result = bufferedReader.readLine())!=null){
                sb.append(result);
            }

            return sb.toString();
        } catch (Exception e) {
            return null;
        }
    }

    public String sendPostRequest(String requestURL,
                                  HashMap<String, String> postDataParams) {

        URL url;
        String response = "";
        try {
            url = new URL(requestURL);

            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setReadTimeout(15000);
            conn.setConnectTimeout(15000);
            conn.setRequestMethod("POST");
            conn.setDoInput(true);
            conn.setDoOutput(true);

            OutputStream os = conn.getOutputStream();
            BufferedWriter writer = new BufferedWriter(
                    new OutputStreamWriter(os, "UTF-8"));
            writer.write(getPostDataString(postDataParams));

            writer.flush();
            writer.close();
            os.close();
            int responseCode = conn.getResponseCode();

            if (responseCode == HttpsURLConnection.HTTP_OK) {
                BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
                response = br.readLine();
            } else {
                response = "Error Registering";
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        return response;
    }

    private String getPostDataString(HashMap<String, String> params) throws UnsupportedEncodingException {
        StringBuilder result = new StringBuilder();
        boolean first = true;
        for (Map.Entry<String, String> entry : params.entrySet()) {
            if (first)
                first = false;
            else
                result.append("&");

            result.append(URLEncoder.encode(entry.getKey(), "UTF-8"));
            result.append("=");
            result.append(URLEncoder.encode(entry.getValue(), "UTF-8"));
        }

        return result.toString();
    }
}

Here is my Main

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

        }

            Bitmap bitmap = params[0];

            HashMap<String,String> data = new HashMap<>();
            data.put(UPLOAD_KEY, uploadImage);

        showFileChooser();
    }
    if(v == buttonUpload){
        uploadImage();
    }

}

Sorry for the long post, but I feel it would be almost redundant to ask a question without providing enough information to have a chance at solving it. Thanks for anyone who takes their time out to help!
