Progress Dialog not displaying using Context in Android

I have a dialog fragment Java class which showing a dialog box it works so fine but the only problem is that the progressDialog is not showing while waiting for the response, this is different from the dialog box, this progressDialog works in AsyncTask while getting the response from the http.
here is my code:

In Android, only Main thread /UI thread can update UI
Other thread cannot update UI but your code is trying to run asynch task(which is a thread which run off/on UI accordingly, awesome!) in a worker thread which is causing the issues.
Solution: Execute Asynch task on UI thread
public void onClick(View view) {
if(view.getId() == R.id.btnCreate) {
if(etStationName.getText().toString().isEmpty() || etAddress.getText().toString().isEmpty() || etContact.getText().toString().isEmpty()) {
Toast.makeText(getActivity(), "All inputs are required!", Toast.LENGTH_LONG).show();
} else {
if(isNetworkAvailable()) {
String param = "n=" + etStationName.getText().toString() + "&a=" + etAddress.getText().toString() + "&c=" + etContact.getText().toString();
String endpoint = Http.url + "?type=addstation&" + param;
endpoint = endpoint.replace(" ", "%20");
new AddStation.StoreStation(getActivity()).execute(endpoint);
} else {
Toast.makeText(getActivity(), "Network unavailable", Toast.LENGTH_LONG).show();

});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,location,gender,birthday");
request.setParameters(parameters);
request.executeAsync();
}
add compile 'org.jsoup:jsoup:1.10.2' in build.gradle and change import org.json.JSONObject;
instead of import com.google.gson.JsonObject; in your Login activity then has method working properly

You'd better get information from response object
String email = response.getJSONObject().getString("email");
String firstName = response.getJSONObject().getString("first_name");
String lastName = response.getJSONObject().getString("last_name");
String gender = response.getJSONObject().getString("gender");
or Create Profile object
Profile profile = Profile.getCurrentProfile();
String id = profile.getId();
String link = profile.getLinkUri().toString();
Log.d("Link",link);
if (Profile.getCurrentProfile()!=null)
{
Log.d("Login", "ProfilePic" + Profile.getCurrentProfile().getProfilePictureUri(200, 200));
}
Log.d("Login" + "Email", email);
Log.d("Login"+ "FirstName", firstName);
Log.d("Login" + "LastName", lastName);
Log.d("Login" + "Gender", gender);
