Get GoogleMap from MapFragment/SupportMapFragment

To get the GoogleMap underlying MapFragment/SupportMapFragment, using getMap() method.

Example to acquire GoogleMap underlying MapFragment/SupportMapFragment.

   FragmentManager myFragmentManager = getSupportFragmentManager();
   SupportMapFragment mySupportMapFragment 
    = (SupportMapFragment)myFragmentManager.findFragmentById(R.id.map);
   myMap = mySupportMapFragment.getMap();

Modify Java code from last exercise "Check if correct Google Play Service available for Google Maps Android API v2.

package com.example.androidmapsv2;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;

import android.app.AlertDialog;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;

public class MainActivity extends FragmentActivity {
 
 final int RQS_GooglePlayServices = 1;
 private GoogleMap myMap;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  
   FragmentManager myFragmentManager = getSupportFragmentManager();
   SupportMapFragment mySupportMapFragment 
    = (SupportMapFragment)myFragmentManager.findFragmentById(R.id.map);
   myMap = mySupportMapFragment.getMap();

 }
 
 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.activity_main, menu);
  return true;
 }

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {
  switch (item.getItemId()) {
     case R.id.menu_legalnotices:
      String LicenseInfo = GooglePlayServicesUtil.getOpenSourceSoftwareLicenseInfo(
        getApplicationContext());
      AlertDialog.Builder LicenseDialog = new AlertDialog.Builder(MainActivity.this);
      LicenseDialog.setTitle("Legal Notices");
      LicenseDialog.setMessage(LicenseInfo);
      LicenseDialog.show();
         return true;
     }
  return super.onOptionsItemSelected(item);
 }

 @Override
 protected void onResume() {
  // TODO Auto-generated method stub
  super.onResume();

  int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
  
  if (resultCode == ConnectionResult.SUCCESS){
   Toast.makeText(getApplicationContext(), 
     "isGooglePlayServicesAvailable SUCCESS", 
     Toast.LENGTH_LONG).show();
  }else{
   GooglePlayServicesUtil.getErrorDialog(resultCode, this, RQS_GooglePlayServices);
  }
  
 }

}

Also correct the layout (a TextView is mis-placed in former version!).

<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"
    tools:context=".MainActivity" >

    <fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment"/>

</RelativeLayout>
