Running a Google Maps App on Android Target 2.3.4 produces a FATAL EXCEPTION
android, eclipse, google-maps, google-play-services
Solution
You are getting an error because you trying to use a `Fragment` on a Android system that don't supports `Fragment`s out of the box. to enable fragment support for this version of OS, you have to add a referece from your project to the `google-support-v4` library. and use the `SupportMapFragment` object in your xml instead of `MapFragment`. you activity would have to extend `FragmentActvitiy` and not an ordinery `Activity` as it's probably does now.
You can read more on how to add a `Google Map API V2` to you application with support for erliear OS versions in a blog post I wrote:
Google Maps API V2
UPDATE:
Please make sure that the following 3 selected jar files`(red)` are located in your Android Dependencies folder `(green)`:
Problem
I have created an Android App that uses Google Maps. I am using Eclipse and the activity layout xml is as follows. ``` <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <fragment android:name="com.google.android.gms.maps.SupportMapFragment" android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout> ``` And here is the Activity class ``` @SuppressLint("ShowToast") public class MapViewActivity extends FragmentActivity { static LatLng currentLatLng; LatLng currentLocation; private GoogleMap map; boolean firstPass = true; double currentLat; double currentlong; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_map_view); showCurrentLocationOnMap(); try { showSheltersAndFuelStops(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } //This will change when SQL connection string is implemented. private void showSheltersAndFuelStops() throws IOException { List<McDonalds> mcdList = new ArrayList<McDonalds>();
