Send the string to url with Android and get response in EditText

Question

I need to use this api,

"http://sconysoft.com/api/md5.php?q="

for doing something like this app :

https://play.google.com/store/apps/details?id=com.sconysoft.md5encoderdecoder&hl=en

Actually, i have one button with Two EditText in Android app, just i need send first string to this api, and if this hash encoded(in url) exist, show that in Edit Text2. and this is above app Codec class :

public class Codec {



    public String decode(String md5) throws Exception {
        try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpResponse response = httpClient.execute(new HttpGet("http://sconysoft.com/api/md5.php?q=" + md5));
            BufferedReader br = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
            JSONObject jo = new JSONObject(br.readLine());

            if(jo.getString("md5").equals(""))
                throw new Exception();

            return jo.getString("word");
        } catch (Exception e) {
        }

        throw new Exception("Can't decode given md5");
    }

}

main :

public boolean isNetworkAvailable() {
        ConnectivityManager cm = (ConnectivityManager) 
          getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = cm.getActiveNetworkInfo();
        if (networkInfo != null && networkInfo.isConnected()) {
            return true;
        }
        return false;
    }
public void decode(View view) {
        final EditText etWord = (EditText)findViewById(R.id.edit1);
        final EditText etMd5 = (EditText)findViewById(R.id.edit2);

        if(!isNetworkAvailable()) {
            etWord.setText("Network unavailable");
            return;
        }

        final ProgressDialog pd = ProgressDialog.show(view.getContext(),"Waiting for Server", "It should take a few seconds");

        Thread th = new Thread() {
            @Override
            public void run() {
                try {
                    Codec cd = new Codec();
                    String md5 = etMd5.getText().toString();
                    try {
                        final String word = cd.decode(md5);
                        runOnUiThread(new Runnable() {
                            public void run() {
                                etWord.setText(word);
                                pd.dismiss();
                            }
                        });
                    } catch (final Exception e) {
                        runOnUiThread(new Runnable() {
                            public void run() {
                                etWord.setText(e.getMessage());
                                pd.dismiss();
                            }
                        });
                    }
                } catch(Exception e) {
                    runOnUiThread(new Runnable() {
                        public void run() {
                            pd.dismiss();
                        }
                    });
                }
            }
        };
        th.start();
    }
}

i also try this codes with same situation in developing, but unfortunately, this codes doesn't work and i cannot see this buttons codes or other something on this app codes.

I am assuming

public void decode(View view)

gets called from the button onClick?

I suggest doing the network call (and managing the progress dialog) in an AsyncTask. Examples:

You update the second EditText (you could use TextView) in the AsyncTask's onPostExecute.
