You may try using AsyncTask for your concern. It's best and preffered way to fetch JSON data
Define AsyncTask like this ..
new BussinessOwnerHttpAsyncTask().execute();
and your AsyncTask class ..
class BussinessOwnerHttpAsyncTask extends AsyncTask<String, Void, String> {
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
// Progress dialog code goes over here ..
pDialog = new ProgressDialog(getParent());
pDialog.setMessage("Please wait ...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
@Override
protected String doInBackground(String... params) {
// Maintaining Shared preferences class for further...
HttpClient httpclient = new DefaultHttpClient();
String myUrl = Your_url_goes_over_here;
String encodedURL = "";
try {
encodedURL = URLEncoder.encode(myUrl, "UTF-8");
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
URL url = new URL(encodedURL);
Log.d("asca", ""+url);
} catch (MalformedURLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Log.i("url", city_name + "~" + country_name);
Log.d("location", request_url+encodedURL);
HttpGet httpget = new HttpGet(request_url+encodedURL);
try {
httpresponse = httpclient.execute(httpget);
System.out.println("httpresponse" + httpresponse);
Log.i("response", "Response" + httpresponse);
InputStream is = httpresponse.getEntity().getContent();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
StringBuilder sb = new StringBuilder();
String recievingDataFromServer = null;
while ((recievingDataFromServer = br.readLine()) != null) {
Log.i("CHECK WHILE", "CHECK WHILE");
sb.append(recievingDataFromServer);
}
myJsonString = sb.toString();
Log.d("manish", myJsonString);
serverSearchData = sb.toString();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return sb.toString();
}
@Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
pDialog.dismiss();
if (myJsonString.length() > 0) {
try {
myJsonObject = new JSONObject(myJsonString);
String your_flag = myJsonObject.getString("flag");
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
Now you are good to go with your queries..
