9.         private final String mCity;
10.         private final String mZip;
11.         private final String mState;
12.         private final ProgressDialog dialog;
13.         private final boolean mNewsletter;
14.  
15.         private boolean registered = false;
16.  
17.         public UserRegisterTask(Activity activity, String email, String password, String firstname, String lastname, String address1, String address2, String city, String zip, String state, boolean newsletter) {
18.             mEmail = email;
19.             mPassword = password;
20.             mFirstName = firstname;
21.             mLastName = lastname;
22.             mAddress1 = address1;
23.             mAddress2 = address2;
24.             mCity = city;
25.             mZip = zip;
26.             mState = state;
27.             mNewsletter = newsletter;
28.             dialog = new ProgressDialog(activity);
29.         }
30.  
31.  
32.         @Override
33.         protected void onPreExecute() {
34.             super.onPreExecute();
35.             registering = true;
36.             dialog.setMessage("Registruji a přihlašuji, prosím čekejte...");
37.             dialog.setCanceledOnTouchOutside(false);
38.             dialog.show();
39.         }
40.  
41.         @Override
42.         protected void onCancelled() {
43.             super.onCancelled();
44.             dialog.dismiss();
45.             registering = false;
46.             Toast.makeText(getBaseContext(), R.string.registration_cancelled, Toast.LENGTH_SHORT).show();
47.         }
48.  
49.         @Override
50.         protected Boolean doInBackground(Boolean... booleans) {
51.             registered = authService.register(mFirstName, mLastName, mEmail, mPassword, mCity, mAddress1, mAddress2, mZip, mState, mNewsletter);
52.             return Boolean.TRUE;
53.         }
54.  
55.         @Override
56.         protected void onPostExecute(Boolean success) {
57.             super.onPostExecute(success);
58.             dialog.dismiss();
59.  
60.             if (success && registered) {
61.                 Toast.makeText(getBaseContext(), R.string.registration_success, Toast.LENGTH_LONG).show();
62.                 redirectToHomepage();
63.             } else {
64.                 email.setError(getString(R.string.email_is_already_registered));
65.                 email.requestFocus();
66.             }
67.         }
68.     }
69.  

 

I found solution error was in the wrong URL of API service it causes that returns HTML 404 instead of JSON
