    copied!<p>So i am fairly new with writing android code and i have been reading the book "Hello, Android" the third edition by Ed Burnette. I was curious and decided to program the GPS section to a map. so i followed the code here initially. <a href="http://mobiforge.com/developing/story/using-google-maps-android" rel="nofollow">http://mobiforge.com/developing/story/using-google-maps-android</a> . in that mobiforge example he provides his own longitude and latitude. but i wanted to mix it with the GPS from the book. </p> <p>I was able to compile and run the code i wrote. However even sending the longitude and latitude via the emulator control the code just refuses to animate to and zoom in. So i am curious why my code does not animate and zoom in.</p> <p>I have tried looking through the documentation to see if i was missing anything to solve this issue. <a href="http://developer.android.com/reference/android/location/LocationManager.html" rel="nofollow">http://developer.android.com/reference/android/location/LocationManager.html</a> and code. google.com/android/add-ons/google-apis/reference/com/google/android/maps/GeoPoint.html but it all seemed to say that i had the appropriate stuff. so i don't know if I'm just missing something.</p> <pre><code>package org.example.GoogleMaps; import java.util.List; import com.google.android.maps.GeoPoint; import com.google.android.maps.MapActivity; import com.google.android.maps.MapController; import com.google.android.maps.MapView; import com.google.android.maps.MapView.LayoutParams; import android.app.Activity; import android.location.Criteria; import android.location.LocationListener; import android.location.LocationProvider; import android.location.Location; import android.location.LocationManager; import android.os.Bundle; import android.view.View; import android.widget.LinearLayout; import android.widget.Toast; public class GoogleMaps extends MapActivity implements LocationListener { MapView mapView; MapController mc; GeoPoint p; LocationManager mgr; String best; Location location; Double lng; Double lat; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mapView = (MapView) findViewById(R.id.mapView); LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom); View zoomView = mapView.getZoomControls(); zoomLayout.addView(zoomView, new LinearLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); mapView.displayZoomControls(true); mgr = (LocationManager) getSystemService(LOCATION_SERVICE); Criteria criteria = new Criteria(); best = mgr.getBestProvider(criteria, true); location = mgr.getLastKnownLocation(best); dumpLocation(location); } @Override protected boolean isRouteDisplayed() { // TODO Auto-generated method stub return false; } public void onLocationChanged(Location location) { dumpLocation(location); } public void onProviderDisabled(String provider) { log("\nProvider disabled: " + provider); } public void onProviderEnabled(String provider) { log("\nProvider enabled: " + provider); } public void onStatusChanged(String provider, int status, Bundle extras) { log("\nProvider status changed: " + provider + ", status = something" + ", extras=" + extras); } private void dumpLocation(Location location) { if (location == null) log("location = null"); else { lat = location.getLatitude(); lng = location.getLongitude(); mc = mapView.getController(); p = new GeoPoint((int)(lat * 1E6), (int)(lng * 1E6)); mc.animateTo(p); mc.setZoom(15); } } private void log(String string) { Toast.makeText(this, string, 6000); } } </code></pre>
