Google Maps Android API v2 and Eclipse

Question

I am new in Google Map and so many things aren't clear enough to me for that reason.So i expect some expert's direction on this regard.I read This Guide and did everything what it says.I use google map api v2 and get a map key.Then i make a sample project following that link and select target version android 2.2(while running the project).But a list of error occurs after running then example in eclipse android emulator.My logcat view shows:

My activity.java is:

package com.googleMapApp;

import android.app.Activity;
import android.os.Bundle;


public class LocationProfileManagerActivity extends Activity {
    /** Called when the activity is first created. */
    //private GoogleMap map;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        //map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

     }
}

Sorry for this lengthy description,but i want to show you exactly what i did.I think as a newcomer i did a lot of mistake on this way.so i expect someone will guide me that.

You are using features only available in later APIs, namely Fragment. If you want to compile to support 2.2, you need to include the Support Library in your project. You will also have to make the following changes to use support fragments instead of regular fragments --

In main.xml, change

class="com.google.android.gms.maps.MapFragment"/>

to

class="com.google.android.gms.maps.SupportMapFragment"/>

and in your activity.java, change

public class LocationProfileManagerActivity extends Activity {

to

public class LocationProfileManagerActivity extends FragmentActivity {

and see @Goldfish comment, you need to test on a real device. – iagreen Jan 30 '13 at 18:32
2.2 isn't mandatory for me(i use that because i don't know actually which android version supports google api v2).So which android version i should use so that i need not include that support library?is it android 4.2 – ridoy Jan 30 '13 at 19:45
@ridoy no its not mandatory, its a new version of google api compared to previous version, it is much better.. – moDev Jan 30 '13 at 19:56
Yes i know it,but i want to know what minimum android version needed to use that api..@Mitesh? – ridoy Jan 30 '13 at 20:13

Maps API v2 cannot be run in an emulator because of its dependency on Google Play Services, which is bundled in the Google Play Store .apk. It can be hacked together though, you can read about it here on the first Google result for "Google maps v2 emulator". Also you can still use V1 for a limited time, you can get started here.

you need to make two changes

Since as you are sdk version is below 12, need to make following change

1) main.xml

Replace

  class="com.google.android.gms.maps.MapFragment"/>

with

class="com.google.android.gms.maps.SupportMapFragment"/>

2) activity.java

Need to extend FragmentActivity instead of Activity

If you want to test in emulator , then download the google_play_services_apk and install it in emulator.
