i am using mapView in my application. on my emulator i am getting black screen instead this map. i have added the permissions and added the <uses-library android:name="com.google.android.maps"/>tag.When i run my app on my emulator it displays black screen instead of map.
public class MainActivity extends MapActivity {
MapView mv;
MapController mc;
GeoPoint mPoint;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mv = (MapView) findViewById(R.id.map);
mv.setBuiltInZoomControls(true);
mv.setSatellite(true);
mc = mv.getController();
mPoint = new GeoPoint(70, 30);
mc.animateTo(mPoint);
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), android.R.drawable.sym_action_email);
MarkerOverlay mo = new MarkerOverlay(bitmap);
mv.getOverlays().add(mo);
}
#Override

return false;

class MarkerOverlay extends Overlay{
Bitmap marker;
public MarkerOverlay(Bitmap bitmap) {
this.marker = bitmap;
}
#Override

super.draw(canvas, mapView, shadow);
Point p = new Point();
mapView.getProjection().toPixels(mPoint, p);
canvas.drawBitmap(marker, p.x, p.y,null);
}

Okay. I think There was some thing wrong with my project. i delete my current project and built a new one and it worked fine.
mc.setZoom(17);
Set your zoom level they get default zoom level 1.Refer article https://developers.google.com/maps/documentation/android/v1/reference/com/google/android/maps/MapView

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.

for details https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/model/Polygon
You just draw a Polygon on your map and fill it with the color you need.

Your are mixing Google Map API V1 with API V2, if you want to use Google Map V2 as it looks by your Manifest file then you can check this blog post I wrote on how to add a Google map API V2 to your application:
Google Map API V2 Android
if you want to use API V1 then you will have to change your Manifest file as it currently set to use API V2, follow this link:
https://developers.google.com/maps/documentation/android/v1/hello-mapview
I am trying to create my first Google Maps in Android using an emulator in Eclipse with no success. All I get for the map is a gray tiled screen that I can zoom but there is no map there. Below is my AndroidManifest file:
<?xml version="1.0" encoding="utf-8"?>

mapView.setSatellite(true);
mapController = mapView.getController();
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,

longitudeView.setText("Longitude is: "
+ String.valueOf(lg));
int latit = (int) (loc.getLatitude() * 1E6);
int longit = (int) (loc.getLongitude() * 1E6);
point = new GeoPoint(latit, longit);
mapController.animateTo(point);
mapController.setZoom(15);
}
}
});
}
#Override
protected boolean isRouteDisplayed() {
return true;
}
#Override
protected boolean isLocationDisplayed() {
return false;
}
}
I am suspecting it may have something to do with my API key which I generated from Google. I provided the SHA1 certificate fingerprints to generate my key. I added at the end of the key my package name which is com.example.herb2 as shown above. I also made sure I was using a Google API device as my emulator. I assume the MD5 fingerprint is used for production. I will appreciate any help on why my map shows nothing but gray.
Have you looked at Google map signed api key errors in Android?
It most probably is that you're using a signed key instead of a debug key.

I'm trying make a simple app in android with google map, but when I run it in emulator look error

You have several problems, the main one being the line:
RelativeLayout linearLayout = (RelativeLayout) findViewById(R.id.mapview);
It's an illegal cast and it does nothing - get rid of it!
As a matter of style your package should be all lower case, make it
package com.jol.android.mapgoogle;
Make sure you compilation unit is called Googlemaps.java and that it matches the class name.
As other posters have pointed out, you need certain permissions in the manifest. This manifest should work and match the other changes I have mentioned.

Put this in the manifest:

This is most likely caused by a signature mismatch. Make sure that you registered your private key from the keystore used to package your application with Google at the maps API signup page and ensure the key that is issued is in your layout file for the MapView.
