android - Location details not getting saved in shared preferences -


I am trying to bring the user's current location and putting those preferences in shared priorities.

My code: - 

  shared context pref1 = this.getSharedPreferences ("LocDetails", Context.MODE_WORLD_READABLE) ;. LocationManager locationManager = (LocationManager) getSystemService (context.LOCATION_SERVICE); Location Location: Author = New GetCurrentLocation (); LocationManager.requestLocationUpdates (LocationManager.GPS_PROVIDER, 0, 0, locationListener); } Public location changed at zero {location location} {latitude = location.getLatitude (); Longitude = location.getLongitude (); Edit SharedPreferences.Editor = pref1.edit (); Edit.putString ("latitude", latitude); Edit.putString ("Longitude", Longitude); edit.commit (); }   
 Error: -

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
