Hi All,
Map services are provided by an
external library that includes the com.google.android.maps package. This
library is not provided as part of the standard SDK. It is provided as a Google
APIs add-on to the android SDK. For the convenience of developers, this add-on
is provided as part of the SDK on the emulator.
Step 1: create an android project in Eclipse, instead
of choosing the target name as Android 2.0, you need to select the target as
Google APIs.
Step2: The Activity
class you create this time should not extend the standard “Activity” class but
should extend the MapActivity class.
Step3: u need to add the following tag in the
AndroidManifext.xml in order to use the external library and permissions:
<uses-library android:name="com.google.android.maps" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
Step 4: Now let us
declare the map view in main.xml in layout folder. To do so, add this
element in order to display the map using MapView.
<com.google.android.maps.MapView
android:id="@+id/myGMap"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:enabled="true"
android:clickable="true"
android:apiKey="0YaGLMeMFKXrhzHL-uSYZSnqXqbGwE6kxF4VwFQ"
/>
This is for sample
java code here :
public class SampleMapActivity extends MapActivity {
MapView myMapView = null;
MapController myMC = null;
GeoPoint geoPoint = null;
double latitude =
17.3667, longitude = 78.4667;
/** Called when the activity is first
created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myMapView = (MapView) findViewById(R.id.myGMap);
geoPoint = new GeoPoint((int) (latitude * 1000000), (int) (longitude * 1000000));
myMapView.setSatellite(false);
myMC = myMapView.getController();
myMC.setCenter(geoPoint);
myMC.setZoom(15);
myMapView.setBuiltInZoomControls(true);
myMapView.displayZoomControls(true);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
public boolean onKeyDown(int
keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_I) {
myMapView.getController().setZoom(myMapView.getZoomLevel() + 1);
return true;
}
else if (keyCode == KeyEvent.KEYCODE_O) {
myMapView.getController().setZoom(myMapView.getZoomLevel() - 1);
return true;
}
else if (keyCode == KeyEvent.KEYCODE_S) {
myMapView.setSatellite(true);
return true;
}
else if (keyCode == KeyEvent.KEYCODE_M) {
myMapView.setSatellite(false);
return true;
}
return false;
}
}
Obtaining a Google Maps Android v1 API Key:
Step1: Locate debug.keystore on your system. It is usually in the
“C:\Users\Sreeni\.android\debug.keystore”.
Step2: Use the keytool utility to generate certificate fingerprint
(MD5). keytool utility that comes with the default JDK installation.
Simply go to the command prompt:
C:\Users\Sreeni>cd C:\Program Files\Java\jdk1.7.0\bin
Then press enter…….
C:\Program Files\Java\jdk1.7.0\bin>
After adding like
this….
C:\Program Files\Java\jdk1.7.0\bin>keytool -v -list
-alias androiddebugkey -keys
tore C:\key\debug.keystore -storepass android -keypass
android
You get the MD5 ..Certificate fingerprints:
MD5:
46:78:01:3F:8E:B0:C0:71:EF:04:A6:85:C9:70:75:3E
SHA1:
25:68:CE:BD:6E:C4:04:DA:87:67:CF:9F:B3:D9:A0:99:5A:89:FD:DC
SHA256:
6B:8F:FD:73:B6:62:33:68:D3:83:23:90:75:6D:40:C8:2A:3E:29:4A:FE:
44:CA:45:01:B6:F7:29:CE:5B:0A:86
This key needs to be
used along with the MapView element declared in the XML layout file as
mentioned in the above
android:apiKey="0YaGLMeMFKXrhzHL-uSYZSnqXqbGwE6kxF4VwFQ".
