Basic Map Example

Postby Rani V » Mon Sep 01, 2008 6:43 am

Hi Guys,

I am writing a simple Map Application, but the emulator shows a blank screen only !! Please suggest me what to do . I tried You solution for proxy settings as well
adb shell sqlite3 /data/data/com.google.android.providers.settings/databases/settings.db ""INSERT INTO system VALUES(99,'http_proxy','[HOST]:[PORT]');""

but it complains Syntax error: "(" unexpected

ehat to do now ?

i am using android-sdk-windows-0.9_beta version and eclipse 3.3

Code :

public class MapExample extends MapActivity {
private MapView mMapView;
private String map = "My Map";

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

mMapView = new MapView(this, map);
// Latitude and Longitude
GeoPoint p = new GeoPoint((int) (28.38 * 1000000),
(int) (77.12 * 1000000));
MapController mc = mMapView.getController();
mc.animateTo(p);
setContentView(mMapView);
mMapView.isSatellite();
}

@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return true;
}

Network error probably means you need to set a permission in the manifest file (child of manifest, you can stick it as the last line before the closing manifest tag):

Syntax: [ Download ] [ Hide ]
Using xml Syntax Highlighting
  1. </uses-permission><uses-permission xmlns:android="http://schemas.android.com/apk/res/android" android:name="android.permission.INTERNET"></uses-permission>
Parsed in 0.001 seconds, using GeSHi 1.0.8.4


It seems you will also have to stick:


Syntax: [ Download ] [ Hide ]
Using xml Syntax Highlighting
  1. <uses-library android:name="com.google.android.maps" />
  2.  
  3.  
  4.  
  5.  
Parsed in 0.000 seconds, using GeSHi 1.0.8.4


As an Application tag child (i think it is new).

I have done this but I am struggling to get the map to move using animate and zoom. There probably exists some more parameters I do not know of... Anyone can add to this?

Sorry, do not forget these permissions too:

  1. <uses-permission android:name="android.permission.ACCESS_LOCATION">
  2.  
  3. </uses-permission><uses-permission android:name="android.permission.ACCESS_GPS">

I built a map demo with zoom controls and some other basic functions. Check out: http://www.marcelp.info/2008/08/28/android-map-demo/
