I'm trying to get my current location on google map but it's giving me a blank map.
this is my fragment
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback, LocationSource.OnLocationChangedListener, GoogleMap.OnMapClickListener {
private GoogleMap mMap;
private LatLng userLocation;
private GoogleApiClient mGoogleApiClient;
private Location mLastLocation;
public LocationManager mLocationManager;
#Override
protected void onCreate(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);
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
}
#Override
public void onLocationChanged(Location location) {
userLocation = new LatLng(location.getAltitude(), location.getLongitude());
Toast.makeText(this, "found you...", Toast.LENGTH_SHORT).show();
MarkerOptions markerOptions= new MarkerOptions();
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(userLocation, 10));
mMap.addMarker(new MarkerOptions().position(userLocation).title("you are here"));
}
#Override
public void onMapClick(LatLng latLng) {
}
}
then that's my manifest
<?xml version="1.0" encoding="utf-8"?>

I am trying to build a location based MAP app and when I try to execute my App, I can view my Markers added to the Mapsactivity, however i don't Map on the activity
I can confirm that I have provide the correct Map key for my activity getting the key from console.developer.com and enabling Google Maps for Android API
Please suggest what could be wrong here

Probably you show desert on the map.
Try change:
map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(mLat,mLon), 20));
to
map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(mLat, mLon), 5));
I have a problem with switching activity from MainActivity to MapsActivity.
GoogleMap shows only cached maps. But when I change in manifest that ActivityMaps is configured as action.Main and category.LAUNCHER everything is working fine. What's the problem?

you need to extend FragmentActivity/AppCompatActivity if you are using SupportMapFragment.
public class Map extends FragmentActivity/AppCompatActivity {
And
FragmentManager myFragmentManager = getSupportFragmentManager();
SupportMapFragment mySupportMapFragment = (SupportMapFragment)myFragmentManager.findFragmentById(R.id.map);
googleMap = mySupportMapFragment.getMap();
You can check Android Map V2
Try this
googleMap = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
Try this...

This is old way for getting map. Google has updated it now.
use
<fragment
android:id="#+id/map"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
in your xml layout.
provide your API key in manifest file as
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="YOUR-API-KEY" />
in your application tag.
also don't extend MapActivity. Instead extend normal Activity
then write below code in your OnCreate
int status = GooglePlayServicesUtil
.isGooglePlayServicesAvailable(getBaseContext());
if (status != ConnectionResult.SUCCESS) {
// Google Play Services are not available
int requestCode = 10;
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this,
requestCode);
dialog.show();
} else {
// Google Play Services are available
// Getting reference to the SupportMapFragment
SupportMapFragment fragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
// Getting Google Map
myMap = fragment.getMap();
// Enabling MyLocation in Google Map
myMap.setMyLocationEnabled(true);
// Getting LocationManager object from System Service
// LOCATION_SERVICE
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
// Creating a criteria object to retrieve provider
Criteria criteria = new Criteria();
// Getting the name of the best provider
String provider = locationManager.getBestProvider(criteria, true);
// Getting Current Location From GPS
Location location = locationManager.getLastKnownLocation(provider);
if (location != null) {
onLocationChanged(location);
}
locationManager.requestLocationUpdates(provider, 20000, 0, this);
}
also add following code on OnResume
int resultCode = GooglePlayServicesUtil
.isGooglePlayServicesAvailable(getApplicationContext());
if (resultCode == ConnectionResult.SUCCESS) {
} else {
GooglePlayServicesUtil.getErrorDialog(resultCode, this,
RQS_GooglePlayServices);
}
that's it.
All the best!
Version 1 googlemaps officially depricated.so just use version 2 and add google-play-services libs.surely it will help to get googlemap.

How can I highlight an area/region on Google Maps v2 Android? I also have a list of geopoints of that particular region. It needs to highlight that region when you scroll to that region. It needs to fill color for nearby region to differentiate from each other so each region should have a different color.
You need to draw a polygon by selecting some points on map. Here is the code.
MainActivity.java
public class MainActivity extends FragmentActivity implements
OnMapClickListener,
OnMapLongClickListener,
OnMarkerClickListener {
private GoogleMap myMap;
Location myLocation;
boolean markerClicked;
PolygonOptions polygonOptions;
Polygon polygon;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager manager = getSupportFragmentManager();
SupportMapFragment mapFragment = (SupportMapFragment) manager
.findFragmentById(R.id.map);
myMap = mapFragment.getMap();
myMap.setMyLocationEnabled(true);
myMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
myMap.setOnMapClickListener(this);
myMap.setOnMapLongClickListener(this);
myMap.setOnMarkerClickListener(this);
markerClicked = false;
}
#Override
public void onMapLongClick(LatLng point)
{
myMap.addMarker(new MarkerOptions()
.position(point).title(point.toString()));
markerClicked = false;
}
#Override
public boolean onMarkerClick(Marker marker)
{
if(markerClicked)
{
if(polygon != null)
{
polygon.remove();
polygon = null;
}
polygonOptions.add(marker.getPosition());
polygonOptions.strokeColor(Color.BLACK);
polygonOptions.strokeWidth(5);
polygonOptions.fillColor(0x884d4d4d);
polygon = myMap.addPolygon(polygonOptions);
marker.remove();
}
else
{
if(polygon != null)
{
polygon.remove();
polygon = null;
}
polygonOptions = new PolygonOptions().add(marker.getPosition());
markerClicked = true;
marker.remove();
}
return true;
}
#Override
public void onMapClick(LatLng point)
{
Toast.makeText(getApplicationContext(),
"Long Press to select locations", Toast.LENGTH_LONG).show();
}
}

now use long press to select points on map and click on marker will draw polygon accordingly.. I thing this will help.
