I'm trying to use google android maps V2 on my samsung s3 mini (4.1.2) however I keep on getting the message "Application has stopped unexpectedly". I had included the google APIs [Android 4.1.2], Google play services library, android-support-v4.jar. Here are the codes: In my AndroidManifest.xml

Your minsdk is 8
<uses-sdk
android:minSdkVersion="8"
Use SupportFragment
.
Use the below in your layout xml
<fragment
class="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Your activity must extend FragmentActivity
.
Also add this to manifest
<permission
android:name="com.Test.projecttest.permission.MAPS_RECEIVE"
android:protectionLevel="signature"/>
<uses-permission android:name="com.Test.projecttest.permission.MAPS_RECEIVE"/>
To initialize map object
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
GoogleMap mMap = fm.getMap();
Make sure you have added support library
Also make sure you imported the below
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.SupportMapFragment;
You need to add this in you manifest: + all that @Raghunandan said ;)
<permission
android:name="your.package.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
<uses-permission android:name="your.package.permission.MAPS_RECEIVE" />
No need to write that in the xml.
just extend the activity to SupportMapFragment
then you will be able to use all google map features
and add this to manifest:
<permission
android:name="com.Test.projecttest.permission.MAPS_RECEIVE"
android:protectionLevel="signature"/>
I displayed the map on a fragment and attached the fragment on the MainActivity
. It makes it more flexible. i did it in the following way:
import com.google.android.gms.maps.CameraUpdate;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.GoogleMap.OnCameraChangeListener;
import com.google.android.gms.maps.GoogleMap.OnMapClickListener;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.CameraPosition;
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 MapFragment extends SupportMapFragment implements
LocationListener, OnMapClickListener, OnCameraChangeListener {
