I am building a navigation drawer application with a google maps fragment in the main activity, when opening app the first time, user IS prompted to activate locations on the emulator, but my location is in the south pacific, and the setmylocationsenabled when set to true doesn't even show..
Summary -Locationbutton not showing -GPS location totally wrong
Thanks in advance
Here is my code
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener,
OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener,
LocationListener {
private GoogleMap mMap;
private Toolbar toolbar;
private DrawerLayout drawer;
private static final String PREFERENCES_FILE = "yourappname_settings";
private boolean NavDrawerUser;
private static final String PREF_USER_LEARNED_DRAWER = "navigation_drawer_learned";
private LocationRequest mLocationRequest;
private GoogleApiClient mGoogleApiClient;
private Location mLastLocation;
