Google Map V2 having trouble to display - google-maps

Question

Any idea what is wrong with my code?
I just want to display the map
but the map having force close error, when I onclick a textview.
I've done the necessary thing at the XML layout, by adding
android:onClick="onClick"
android:clickable="true"
I've check the map.java, actually, it is working fine.
I've also check the onclick textview too, it is also working fine.
However, when I want to link both together, meaning show map.java upon onclick textview. However it gave me error.
Can someone advice me what is wrong with my code?
Thank you in advance.
the onclick textview code:
I've implements the onclicklistener
#Override
public void onClick(View v) {
//TODO Auto-generated method stub
startActivity(new Intent(SingleMenuItemActivity.this,
map.class));
}
map.java
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
public class map extends FragmentActivity {
private GoogleMap map;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
map = fm.getMap();
map.animateCamera(CameraUpdateFactory.zoomIn());
}
}
map_shown.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
class="com.google.android.gms.maps.SupportMapFragment"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

Probably this line
map = fm.getMap();
returns you null, and then you call something on null object -> exception
