How to Begin and Develop?Answer is step by step.And learning example.

Downloading Google Play ServicesOpen Eclipse ⇒ Windows ⇒ Android SDK Manager

Importing Google Play Services into EclipseFile ⇒ Import ⇒ Android ⇒ Existing Android Code Into Workspace

Windows os :android-sdk-windows\extras\google\google_play_services\libproject\google-play-services_lib

Getting the Google Maps API keyWindow ⇒ Preferences ⇒ Android ⇒ Build

We need to copy SHA1 fingerprint like this : C1:C8:C4:5F:15:82:BC:85:E2:5B:CA:F2:6F:C3:EF:02:01:A1:F2:F4

Now open Google API Console If you have no Google Account…please hurry to registry

Enabled Google Maps Android API v2


New Project


Registered apps


Package Name要與專案package相同

⾛走上這條路都是為了它...AIzaSyDacsY4MMgCfjc5A4IwLS6LQpz1ykIgzJk

Creating New ProjectFile ⇒ New ⇒ Android Application Project

We need to copy Map API Key like this : AIzaSyDacsY4MMgCfjc5A4IwLS6LQpz1ykIgzJk

Google Play Services project as a library to use project.

We need to copy Map API Key like this : AIzaSyDacsY4MMgCfjc5A4IwLS6LQpz1ykIgzJk

So right click on project and select properties.

Add the Map Key in the manifest file.We need to copy Map API Key like this : AIzaSyDacsY4MMgCfjc5A4IwLS6LQpz1ykIgzJk

<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" android:value="API_KEY"/>

Google maps needs following permissions and features.

ACCESS_NETWORK_STATE – To check network state whether data can be downloaded or notINTERNET – To check internet connection status WRITE_EXTERNAL_STORAGE – To write to external storage as google maps store map data in external storageACCESS_COARSE_LOCATION – To determine user’s location using WiFi and mobile cell data ACCESS_FINE_LOCATION – To determine user’s location using GPS OpenGL ES V2 – Required for Google Maps V2

Let’s Coding.

Placing a Marker// latitude and longitude double latitude = ; double longitude = ; // create marker MarkerOptions marker = new MarkerOptions().position(new LatLng(latitude, longitude)).title("Hello Maps "); // adding marker googleMap.addMarker(marker);

Changing Marker Color// ROSE color icon marker.icon(BitmapDescriptorFactory.defaultMarker( BitmapDescriptorFactory.HUE_ROSE)); // GREEN color icon marker.icon(BitmapDescriptorFactory.defaultMarker( BitmapDescriptorFactory.HUE_GREEN)); !

Custom Marker Icon

// latitude and longitude double latitude = 17.385044; double longitude = 78.486671; // create marker MarkerOptions marker = new MarkerOptions().position(new LatLng(latitude, longitude)).title("Hello Maps"); // Changing marker icon marker.icon(BitmapDescriptorFactory.fromResource(R.drawable.my_marker_icon))); // adding marker googleMap.addMarker(marker);

Moving Camera to a Location with animation

CameraPosition cameraPosition = new CameraPosition.Builder().target(

new LatLng(17.385044, 78.486671)).zoom(12).build();

googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));

Changing Map TypegoogleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);

googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);

googleMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);

googleMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);

googleMap.setMapType(GoogleMap.MAP_TYPE_NONE);
