add google maps in an android application

I'm new in Android development. I want to add Google maps to my application. I have done lots of searches but still the same problem arises when I run the application "Unfortunately , application has stopped"
So this is my java class
package com.example.hellomap;
import com.google.android.maps.MapView;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map_main);
MapView map =(MapView) findViewById(R.id.map);
}
}
the xml file :
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"/>
and the Manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.hellomap"
android:versionCode="1"
android:versionName="1.0" >

Thanks for help :)

EXCEPTION :- ClassNotFoundException
please check GooglePlayService Library Project First.
Second Thing You Can Not Type Cast Fragment To Map View, please read this
Update:-
Follow The Step:-
1)Create New Project
2)Import GooglePlayService Library project into Your Workspace.
3)assign Google play Service library project as library project to your project
4)now add Map Fragment/Supported Map Fragment into your activity layout file
5)make sure this class found
how to check==>press control Key from keyboard and click on class name id you found class then it's okay other wise fix it first.
i prefer to use Supported Fragment.
6)define all permission as describe in link i posted previously.
6)now its time to generate api key for map ,follow the step from given link.
Thanks i hope its help

Anyonee have ide for this problem?
i'am very confuse, i hope u can solve this problem.

actually reading the error help a lot you know
The meta-data tag in your app's AndroidManifest.xml does not have the right value. Expected 4030500 but found 0. You must have the following declaration within the <application> element: <meta-data android:name="com.google.android.gms.version" android:value="#integer/google_play_services_version" />

Your code is fine but for Google play service revision 13 you should have to add one more meta tag in your manifest.xml.Insert it inside your application tag.So there will be two meta tags in your application tag.If you still need any help.Just follow this link
<meta-data android:name="com.google.android.gms.version" android:value="4030500" />

Here is my main activity xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" >
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
What exactly could be causing this? As far as I am aware, the vast majority of users are not experiencing this and I can't think of any way to try and replicate it.

Try the following, it worked for me:
<application>
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="API KEY" />
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
</application>

I suggest you to make like this:
<fragment
android:id="#+id/map"
class="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Not android:name. Let me know if it works.

And here is the solution! NullPointerException from Google maps
Insert the SD card if you don't have an internal one! Google din't fix that problem since 2013.

On your main activity xml, change android:name="com.google.android.gms.maps.SupportMapFragment"
to this :
class="com.google.android.gms.maps.SupportMapFragment"

it says that class is not there, but it IS there. I tried to configure things in my project's build path, but not too sure what to tweak there.
And here is how I start my Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="business.premium"
android:versionCode="1"
android:versionName="1.0" >
<supports-screens android:largeScreens="true" android:normalScreens="true" android:smallScreens="true"/>
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="15"/>
<uses-permission android:name="android.permission.INTERNET" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/CustomTheme"
android:name="MyApplication"
android:debuggable="true">
<activity
android:name=".Problemio"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Any thoughts on how to solve this, or what to look into? Thanks!

Its because you specified the "android:name" attribute in the application node in the manifest file.
Do not use the android:name attribute!
It, misleadingly, does not have anything to do with the name of your app and is actually the name of an extra class to load before loading your application. That's why you are getting the ClassNotFoundException.
Remove it and it should work:
<application
android:icon="#drawable/icon"
android:label="#string/app_name"
android:description="#string/help_text" >
