    text
    copied!<p>I try to implement google map v2 and all I get are errors. I've followed these tutorials: <a href="http://www.vogella.com/articles/AndroidGoogleMaps/article.html" rel="nofollow">http://www.vogella.com/articles/AndroidGoogleMaps/article.html</a> and <a href="http://blog-emildesign.rhcloud.com/?p=435" rel="nofollow">http://blog-emildesign.rhcloud.com/?p=435</a> Well I've done everything like in the tutorials (I use google api 8 so sometimes I had to change something - e.g. SupportFragmentManager instead of FragmentManager) my activity (modified Lars Vogel's example):</p> <pre><code>import android.os.Bundle; import android.support.v4.app.FragmentActivity; import com.google.android.gms.common.GooglePlayServicesNotAvailableException; import com.google.android.gms.maps.CameraUpdateFactory; import com.google.android.gms.maps.GoogleMap; import com.google.android.gms.maps.MapsInitializer; import com.google.android.gms.maps.SupportMapFragment; import com.google.android.gms.maps.model.BitmapDescriptorFactory; import com.google.android.gms.maps.model.LatLng; import com.google.android.gms.maps.model.Marker; import com.google.android.gms.maps.model.MarkerOptions; public class MapActivity extends FragmentActivity { static final LatLng HAMBURG = new LatLng(53.558, 9.927); static final LatLng KIEL = new LatLng(53.551, 9.993); private SupportMapFragment map; private GoogleMap mMap; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_map); try { MapsInitializer.initialize(this); } catch (GooglePlayServicesNotAvailableException e) { // TODO Auto-generated catch block e.printStackTrace(); } map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)); mMap = map.getMap(); Marker hamburg = mMap.addMarker(new MarkerOptions().position(HAMBURG) .title("Hamburg")); Marker kiel = mMap.addMarker(new MarkerOptions() .position(KIEL) .title("Kiel") .snippet("Kiel is cool") .icon(BitmapDescriptorFactory .fromResource(R.drawable.ic_launcher))); // Move the camera instantly to hamburg with a zoom of 15. mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15)); // Zoom in, animating the camera. mMap.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null); } </code></pre> <p>}</p> <p>my layout:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:map="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MapActivity" &gt; &lt;fragment class="com.google.android.gms.maps.SupportMapFragment" android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p>I got NPE at Marker hamburg. When I comment out this line I get next error at Marker kiel - ibitmapdescriptorfactory is not initialized. So I guess that's problem with .icon method on Marker - in the hamburg case it's null/default and in the second case is not initialized. I have no idea how to solve this.</p>
