I am looking to display a Google Maps Display on a fragment layout within android studio. I have already downloaded Google play services in the SDK and have made the appropriate changes to my gradle files (I Think). I have made some changes to the android manifest file as well to grant user permissions etc. At run time a google maps display renders but the lng and lat are set to 0 so when the map displays, it shows me an area around Africa. I have made methods in the java file such as onMapReady, which is supposed to display the map at a different location and have it more zoomed in. The onMapReady function calls another method called goToLocationZoom, which holds the required functionality to allow the map to move to this location but for some reason everytime I run it, it always stays to the area around Africa, even though I have changed the lng and lat values. I am following a tutorial to achieve this, and in there Activty_home.XML file, they have their layout to linear, whilst mine is set to constraint but I don't think this would cause the issue. Does anyone know how to display the map to the lng and lat values that I have specified in the java file?
Below is my Java file code:
com.example.cmpkbest.lifestylefitnessapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import com.google.android.gms.maps.CameraUpdate;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.model.LatLng;
public class ViewLifestyles extends AppCompatActivity implements
GoogleMap mGoogleMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view_lifestyles);
initMap();
}
private void initMap () {
MapFragment mapFragment = (MapFragment) getFragmentManager ().findFragmentById(R.id.mapFragment);
mapFragment.getMapAsync(this);
}
#Override
public void onMapReady(GoogleMap googleMap) {
mGoogleMap = googleMap;
goToLocationZoom (53.408743, -2.984154, 15);
}
private void goToLocation (double lat, double lng) {
LatLng ll = new LatLng(lat, lng);
CameraUpdate update = CameraUpdateFactory.newLatLng(ll);
mGoogleMap.moveCamera(update);
}
private void goToLocationZoom (double lat, double lng, float zoom) {
LatLng ll = new LatLng(lat, lng);
CameraUpdate update = CameraUpdateFactory.newLatLngZoom(ll, zoom);
mGoogleMap.moveCamera(update);
}
}
Below is my Manifest code:

I also had a project doing same output. I handle it this way.
So first you have to initialize the map
if (mMap == null) {
mMap = ((MapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap();
// check if map is created successfully or not
if (mMap == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
Then i call setUpMap right after initializing it, not relying on onMapReady
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(
lastLocation.getLatitude(), lastLocation.getLongitude()), 15));
mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
mMap.setIndoorEnabled(true);
mMap.setMyLocationEnabled(true);
Hope this helps

I have created activity: MapsActivity, which shows my location on map.
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
private LocationManager locationManager;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
Location location = locationManager.getLastKnownLocation(locationManager.getBestProvider(criteria, false));
double lat = location.getLatitude();
double lng = location.getLongitude();
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
mMap.setMyLocationEnabled(true);
// Add a marker in Sydney and move the camera
LatLng place = new LatLng(lat,lng);
mMap.addMarker(new MarkerOptions().position(place).title("Marker in Sydney"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(place));
}
}
I created MainActivity, with a button, which I want to click to move to MapsActivity, here it's code:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void showMyLocation(View view){
Intent intentControls = new Intent(this, MapsActivity.class);
startActivity(intentControls);
}

My question is how do I run Google Map Activity from another activity, using Intent?
keep below permission above application Tag
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
<application
......
.....
<activity>
.....
</activity>
</application>
(or)
You are getting this error most probably, due to un-availability of
GPS Providers. Please ask the person to check settings if Gps
Provider or Network Provider has been enabled into Location
settings.
I'm trying to add Google Maps. However, after building the apk from Build > Generate Signed apk and installing it to a real device, the activity only shows a blank screen, with the Google logo in the lower left. Is there something wrong with the following codes?

Blank map is caused by incorrect google_maps_key. Note that there are 2 different keys - one for debug, one for release build. You have to register both on https://console.developers.google.com/. To determine your release key run something like this in your project directory:
"c:\Program Files\Java\jdk1.8.0_20\bin"\keytool -list -v -keystore keystore.jks

As seen on the Android docs : https://developers.google.com/android/reference/com/google/android/gms/maps/GoogleMap.OnMyLocationChangeListener
GoogleMap.OnMyLocationChangeListener is now deprecated. The tutorial you are using is simply already too old.
From the link above, you will be able to be redirected to newer tutorials and how-to guides (which will also solve the setMyLocationEnabled error).
EDIT : What I recommended is now deprecated, such is life in software development. If you're looking for the newest way of doing it, check out the Android documentations.
I want to show user location as per address submitted by him. For that i am using Geocoder. But i got following error.

<!--
The API key for Google Maps-based APIs is defined as a string resource.
(See the file "res/values/google_maps_api.xml").
Note that the API key is linked to the encryption key used to sign the APK.
You need a different API key for each encryption key, including the release key that is used to
sign the APK for publishing.
You can define the keys for the debug and release targets in src/debug/ and src/release/.

You need to add the package name and SHA certificate fingerprint on the developers console, under your key. Have you done that?
You need to add map key to show googlemap on your application.I didn't see it in the manifest file,i see only key for using GeoCoder
Try after adding your google map key. Example is shown below
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" />
Try this, it may help you:
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = null;
try {
addresses = geocoder.getFromLocationName("Location String", 1);
} catch (IOException e) {
e.printStackTrace();
}
Address address = addresses.get(0);
if(addresses.size() > 0) {
double latitude = addresses.get(0).getLatitude();
double longitude = addresses.get(0).getLongitude();
LatLng latLng = new LatLng(latitude, longitude);
mMap.addMarker(new MarkerOptions().position(latLng));
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
mMap.animateCamera(CameraUpdateFactory.zoomTo(10));
}
After tons of tries I couldn't found how to solve this.
Android won't resolve the symbol 'mapView' on:
mMapView = (MapView) v.findViewById(R.id.mapView);
What i'm trying to do is to get google maps to work on the emulator.
I know this code is working on another PC, so my guess here that there's something else.. (a system issue or google maps api problem)
here's the code.
Can anyone help? Thank you..
