Unable to instantiate activity ComponentInfo java.lang.ClassNotFoundException: util.kalyan.HelloGoogleMapsActivity

I have included all the necessary fields correctly. But still, I am not able to launch the Google map on my emulator. Checked the internet permissions also. Getting error like:

E/AndroidRuntime(2064): java.lang.RuntimeException: Unable to instantiate activity 
ComponentInfo{util.kalyan/util.kalyan.HelloGoogleMapsActivity}: 
java.lang.ClassNotFoundException: util.kalyan.HelloGoogleMapsActivity

Please find below my code.

HelloGoogleMapsActivity.java

package util.kalyan;
import android.os.Bundle;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
import util.kalyan.R;
public class HelloGoogleMapsActivity extends MapActivity
{
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        MapView mapView = (MapView) findViewById(R.id.mapview);
        mapView.setBuiltInZoomControls(true);
    }    
    @Override
    protected boolean isRouteDisplayed()
    {
        return false;
    }
}

AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"      package="util.kalyan"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="14" />
    <uses-library android:name="com.google.android.maps"></uses-library>
    <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" >
        <activity android:name=".HelloGoogleMapsActivity"    android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar">
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-  permission>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
    <uses-permission android:name="android.permission.INTERNET" />
</manifest>

Any one please help me in this at the earliest. Thanks in advance.

You emulator target should be one that includes Google APIs (Google Inc.).

Change the android:name in activity definition

from

<activity android:name=".HelloGoogleMapsActivity" ../>

to

<activity android:name="util.kalyan.HelloGoogleMapsActivity" ../>
