Im not sure whats wrong but Im trying to get my google maps fragment to zoom in to a particular location on start. For some reason, it is not working and still zooms in to africa by default. Here is my code.
public class OutbreakMap extends Activity implements LocationListener {
double lat=50;
double longi=50;

locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
LocationManager service = (LocationManager) getSystemService(LOCATION_SERVICE);
boolean enabled = service.isProviderEnabled(LocationManager.GPS_PROVIDER);
// Check if enabled and if not send user to the GSP settings
// Better solution would be to display a dialog and suggesting to
// go to the settings
if (!enabled) {
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
// set title
alertDialogBuilder.setTitle("Turn On Your GPS");
// set dialog message
alertDialogBuilder
.setMessage("Please turn on your GPS to track sickness in your area!")
.setCancelable(false)
.setPositiveButton("Yes",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
// if this button is clicked, close

startActivity(intent);
}
})
.setNegativeButton("No",new DialogInterface.OnClickListener() {

The LogCat is not showing any errors. Thanks for the help!
You are adding second SupportMapFragment in code on top of Fragment having GoogleMap you interact with. Just remove unnecessary code.
Use SupportMapFragment
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
/>
GoogleMap gm;
gm = ((SupportMapFragment(getSupportFragmentManager().findFragmentById(R.id.map))).getMap();
Comment out the following lines of code
mMapFragment = MapFragment.newInstance();
FragmentTransaction fragmentTransaction =
getFragmentManager().beginTransaction();
fragmentTransaction.add(R.id.map, mMapFragment);
fragmentTransaction.commit();
and its going to work like a charm.

Any help in the right direction would be greatly appreciated! Many Thanks.
You can use Google Maps default current location setting it with gMap.setmylocationenabled(true). Or you can use moveCamera(CameraUpdate update) when getting your current location in your locationListener.
I am new to android development. I am working on Android Studio and developing an app on which i have 3 tabs. One tab is for maps, second is for camera and 3rd is for pictures. I am using google map for viewing map. The map will show current GPS location of the user. For this i am using a mapViewand done all of the work, but still unable to view the map.

When i run my app i just see an empty tab, map doesn't shows. I must be missing something and i don't know what. I have searched many articles on it but couldn't find appropriate help so that's why i am posting a question here.
Any help would be highly appreciated
I have made an app which gives you current latitude and longitude using GPS service.
Now i plan to show location on MAP based on this co-ordinates
I want to create 2 activities. 1st already created in which i am showing latitude and longitude in TextView. in 2nd activity i want to display map in which location will be displayed. to go from one activity to another i will use a button in 1st activity.
here is my code (Not Full)
protected LocationManager locMan;
protected LocationListener locLis;
protected Context contex;
TextView txtview;
String lat,provider;
protected String latitude,longtitude;
protected boolean gps_enable,network_enable;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#F44336")));
txtview = (TextView)findViewById(R.id.locView);
locMan = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locMan.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
}
#Override
public void onLocationChanged(Location loc){
txtview = (TextView)findViewById(R.id.locView);
txtview.setText("Latitude = "+loc.getLatitude()+", Longitude = "+ loc.getLongitude());
}
Note :- I have refer javapapers website for my current app

Create Map Activity and pass the location via bundle or save it in sharedpreference
public class MapActivity extends ActionBarActivity{
private GoogleMap googleMap;
FragmentManager fm;
private Location mLocation;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fm = getSupportFragmentManager();
// get location from bundle or sharedprefs
// mLocation = ...
try {
if (googleMap == null) {
googleMap = ((SupportMapFragment) fm.findFragmentById(R.id.map)).getMap();
googleMap.getUiSettings().setZoomGesturesEnabled(true);
}
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
} catch (Exception e) {
e.printStackTrace();
}
MarkerOptions TP = new MarkerOptions().title("title").position(new LatLng(mLocation.getLatitude(), mLocation.getLongitude())).icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_map_marker));
googleMap.addMarker(TP);
}}
xml layout for this activity is
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
You need to use MapView and MyLocationOverLay to the map, as Android will handle displaying the user's location for you.
map=(MapView)findViewById(R.id.whatever_your_mapview_id_is);
map.getOverlays().add(new MyLocationOverlay(this, map));
Refer : display google maps using coordinates obtained using gps
You can pass the location to the Maps Activity using a LatLng Object since it's parcelable, see this answer.
Then, you could create a Marker in your MapsActivity, and use the CameraPosition class to move the map view to the specified location.
First, make sure that you have double values with the current location in your existing Activity:
//instance variables:
double lat;
double lon;
Set lat/lon in your onLocationChanged() callback:
#Override
public void onLocationChanged(Location loc){
lat = loc.getLatitude(); //added
lon = loc.getLongitude(); //added
txtview = (TextView)findViewById(R.id.locView);
txtview.setText("Latitude = "+loc.getLatitude()+", Longitude = "+ loc.getLongitude());
}
Create a Button in your layout in your existing Activity, and in the click listener you would create a LatLng object and send it in the Intent to the Maps Activity:
Button b = (Button) findViewById(R.id.button);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
LatLng fromPostion = new LatLng(lat, lon );
Bundle args = new Bundle();
args.putParcelable("location", fromPostion);
Intent i = new Intent(this, MapsActivity.class);
i.putExtras(args);
startActivity(i);
}
});
Then, in your Maps Activity, you would get the LatLng object in onCreate() from the Bundle:
LatLng latlng; //Create as instance variable
In onCreate():
Bundle b = getIntent().getExtras();
if (b != null){
latlng = (LatLng) b.getParcelable("location");
}
Then, add the Marker at that location and set the camera position and zoom:
private void setUpMap() {
mMap.getUiSettings().setMapToolbarEnabled(true);
mMap.getUiSettings().setZoomControlsEnabled(true);
mMap.setMyLocationEnabled(true);
MarkerOptions marker = new MarkerOptions().position(latlng).title("My Location");
// Changing marker icon
marker.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE));
Marker m = mMap.addMarker(marker);
//move camera position and zoom to specified location
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(latlng).zoom(8).build();
mMap.animateCamera(CameraUpdateFactory
.newCameraPosition(cameraPosition));
}
Your full Maps Activity might look something like this:
public class MapsActivity extends ActionBarActivity implements
GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener, OnMapReadyCallback {
private GoogleMap mMap;
LatLng latlng;
LocationRequest mLocationRequest;
GoogleApiClient mGoogleApiClient;
LocationManager manager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
Bundle b = getIntent().getExtras();
if (b != null){
latlng = b.getParcelable("location");
}
manager =(LocationManager) getSystemService(Context.LOCATION_SERVICE);
setUpMapIfNeeded();
buildGoogleApiClient();
mGoogleApiClient.connect();
}
#Override

Note that you will also need to enable Google Maps in the Google Developer Console, and include Google Play Services in your build.gradle file (update version with the version that you are using):
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.1.1'
compile 'com.google.android.gms:play-services:7.3.0'
}
The last thing is to set up your AndroidManifest.xml for the Google Maps API v2:
permissions:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<!--
The ACCESS_COARSE/FINE_LOCATION permissions are not required to use
Google Maps Android API v2, but are recommended.
-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
meta-data tags, make sure they are inside the application tag:
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
<meta-data
android:name="com.google.android.maps.v2.API_KEY"

I am having some prolems with my google maps app. For now the app was only suppost to get my location em zoom in it, but is not working. My location aways ends in the top of the map. Here is my code:

I can only test in my device. The map is working fine but i cannot get my position on the center of the screen right away only clicking at the mylocationbutton. Somebody can help me?
Just declare a point where you want to center your point.
LatLng cur_Latlng = new LatLng(21.0000, 78.0000);
gm.moveCamera(CameraUpdateFactory.newLatLng(cur_Latlng));
gm.animateCamera(CameraUpdateFactory.zoomTo(4));
the desired zoom level is in the range of 2.0 to 21.0.
// try this
#Override
public void onLocationChanged(Location location) {
LatLng latlong = new LatLng(location.getLatitude(),
location.getLongitude());
googleMap.animateCamera(CameraUpdateFactory.newLatLng(latlong));
googleMap.animateCamera(CameraUpdateFactory.zoomBy(15));
}
Your min sdk is 8. You should use SupportMapFragment. Your class must extend FragmentActivtiy
Check the line above developers guide heading in the below link
https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/MapFragment
<fragment
class="com.google.android.gms.maps.SupportMapFragment"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Use SupportMapFragment
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
GoogleMap mMap = fm.getMap();
Make sure you have added support library
Also make sure you imported the below
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.SupportMapFragment
To zoom
CameraUpdate update = CameraUpdateFactory.newLatLngZoom(latlong,20);
googleMap.moveCamera(update);
This is working Current Location with zoom for Google Map V2
double lat= location.getLatitude();
double lng = location.getLongitude();
LatLng ll = new LatLng(lat, lng);
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(ll, 20));
Note that the My Location layer does not return any data. If you wish to access location data programmatically, use the Location API.
In your MainActivity (onCreate Method)
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(MainActivity.this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
On method onMapReady
#Override
public void onMapReady(GoogleMap googleMap) {
GoogleMap mMap = googleMap;
// Set blue point on the map at your cuurent location
mMap.setMyLocationEnabled(true);
// Show zoon controls on the map layer
mMap.getUiSettings().setZoomControlsEnabled(true);
//Show My Location Button on the map
mMap.getUiSettings().setMyLocationButtonEnabled(true);
}
on method onConnected
#Override
public void onConnected(Bundle bundle) {
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if (mLastLocation != null) {
LocationListener.latlonInit= new LatLng(mLastLocation.getLatitude(),mLastLocation.getLongitude());
CameraPosition target = CameraPosition.builder().tilt(66.0f).target(LocationListener.latlonInit)
.zoom(MainActivity.ZOOM).build();
mMap.moveCamera(CameraUpdateFactory.newCameraPosition(target));
}
}
You class should extend Fragment Activity
public class MainActivity extends FragmentActivity {
//assign any arbitrary value to GPS_ERRODIALOG_REQUEST
private static final int GPS_ERRORDIALOG_REQUEST = 9001;
GoogleMap googlemap;
}
for Google Service Ok method I would do Following:
public boolean isGooglePlayOk(){
int isAvailable = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if (isAvailable == ConnectionResult.SUCCESS) {
return true;
}
else if(GooglePlayServicesUtil.isUserRecoverableError(isAvailable)){
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(isAvailable, this, GPS_ERRORDIALOG_REQUEST);
dialog.show();
}
else {
Toast.makeText(this, "Can't connect to Goolge Play", Toast.LENGTH_SHORT).show();
}
return false;
}
In the .xml file, when you declare the fragment, you need to support Map Fragment since your min skd is 8:
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:maps="http://schemas.android.com/apk/res-auto"
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
activity_map.xml is for displaying map if condition is true for setMap else go to you regular activity_main.xml.
public class MainActivity extends FragmentActivity {
GoogleMap mMap;
if (isGooglePlayOk()) {
setContentView(R.layout.activity_map);
if (setMap()) {
mMap.setMyLocationEnabled(true);
}
else {
//your code
}
}
else {
setContentView(R.layout.activity_main);
}
method for setMap:
private boolean setMap() {
if (mMap == null) {
SupportMapFragment mapFrag =
(SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mMap = mapFrag.getMap();
}
return (mMap != null);
}
If you want to automatically zoom to some point in google maps v2 u can do like this
private float previousZoomLevel = 13.00f;
LatLng zoomPoint = new LatLng(12.977286, 77.632720);
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(zoomPoint,previousZoomLevel));
here previousZoomLevel is level of zoom
First of all, I´ve been searching for an answer for this the whole evening. I have read many of the questions -probably all- asking why OnloCationChanged is not called... nothing helped me.
I have a Fragment that displays a map. I can add markers to it and it also shows the current location of the user correctly. Everything seems to be ok but, I want to zoom in the user´s location and that´s why I need the method "OnLocationChanged" to be called.
Also, locationManager.getLastKnownLocation(provider) returns always null.
I have tested this in a real device.
Here is my configuration, I hope somebody can point me in the right direction.
Thanks

I think in your onlocation change it runs but the you remove the updates and it doesn't run any more
Comment out this line in onlocationchanged
locationManager.removeUpdates(this);
And your getbestprovider method use true instead of false
