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" >

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

Starting with Android Google Maps API V2

I am newbie on Android Google Maps API and I was trying to develop a small app using the API. I use as a reference the Google documentation form: https://developers.google.com/maps/documentation/android/ and I follow all the step with caution. When I build it and install it on to my device (Android 2.3.6) the app crash. I follow all the instructions to sign the app and get the API key for this specific app, tried all the step of the documentation several times without any good results. Please, can someone help me with this? I there something missing?
Thank you!

First thing as you are having the API level 8 or below so you have to use the SupportMapFragment instead of MapFragment as below in your layout 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.SupportMapFragment"/>
Second thing you have to extend the FragmentActivity instead of Activity :
public class MainActivity extends FragmentActivity {
Do the above changes and then run your application.

Starting FragmentActivity from Activity with Intent

I'm getting a force close every time I try to start a FragmentActivity from an Activity using an Intent. Here's the code from the Activity:
Intent intent = new Intent(getApplicationContext(), OrgHome.class);
intent.putExtra("Username", organization_name.getText().toString());
startActivity(intent);
And here's the logcat:

OrgHome.class is defined in the manifest correctly. What's going on here?
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.project3.organizations"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="OrgHome"></activity>
</application>
</manifest>

Change the manifest:
Use this if OrgHome is in the same place as MainActivity
<activity android:name=".OrgHome" />
Use this if it's in a sub-folder
<activity android:name=".sub.path.to.OrgHome" />
Or specify the whole path
<activity android:name="entire.path.to.OrgHome" />

for addressing the Fragment activities you should write (getactivity(),nameofOtherActivity.class); and you should be all right.

Unable to load webpage using WebView in Android

I have recently taken up Android Development and I was looking to using the WebView display webpages. I picked up from the sample that was given on Google site and for some reason the emulator kept saying page was not available. I searched in StackOverflow and found links relating to WebViewClient. I tried that also but no luck there, I have checked multiple times about the manifest entry for internet permission and its there. As a test I ran the browser available within the emulator and sure enough my firewall popped up a question on whether to allow it access or not. The pop up never came to me when I was running it from program. The code that I have is what is there Google pages
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("http://www.google.com");
mWebView.setWebViewClient(new HelloWebViewClient());
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
I tried loading simple html directly using loadData and it worked fine. I am at loss as to what is happening and how this can be resolved. I would appreciate any help on this.

Got it. For some reason the order in which the permission is set matters a lot. I changed the order of my permission setting in manifest file and it worked. Here's the modified manifest

I am not sure what is the significance of this but would appreciate if anyone could elaborate.

Use this code .shouldOverrideUrlLoading() not use compulsary.use this code and please reply me this code work or not

Your code looks fine. I would make sure internet is working correctly on the emulator by browsing a few pages on the Android Browser. I have had problems before where the emulator would lose network access.
