progressDialog.setMessage("Please wait downloading your data...");
progressDialog.show();
progressDialog.setOnCancelListener(new OnCancelListener() {
public void onCancel(DialogInterface arg0) {
MyAsyncTask.this.cancel(true);
}
});
}
@Override
protected Void doInBackground(String... params) {
// set your url of json file
String url_select = "http://yoururlhere.com";
ArrayList<NameValuePair> param = new ArrayList<NameValuePair>();
try {

// HttpClient is more then less deprecated. Need to change to
// URLConnection

HttpEntity httpEntity = httpResponse.getEntity();
// Read content & Log
inputStream = httpEntity.getContent();
} catch (Exception e4) {

// Convert response to string using String Builder

}
inputStream.close();
result = sBuilder.toString();
} catch (Exception e) {
}
return null;
} // protected Void doInBackground(S
protected void onPostExecute(Void v) {
// parse JSON data
