Android java.lang.NoClassDefFoundError when launching new activity

I am getting a java.lang.NoClassDefFoundError when I try to launch my new activity. Below is my AndroidManifest.xml:

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

    <uses-sdk android:minSdkVersion="15" />
  <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >

            <activity
                android:name=".LoginActivity"
                android:label="Login to your Account">
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity
            android:name=".RegisterActivity"
            android:label="Register New Account">
        </activity>

        <activity
            android:name=".GoogleMapsActivity"
            android:label="Google Maps">
        </activity>

        <uses-library android:name="com.google.android.maps"/>

    </application>

</manifest>

Code for GoogleMapsActivity.java

package com.practice.googlemaps;

import android.os.Bundle;

import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;

public class GoogleMapsActivity extends MapActivity {

  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() {
      // TODO Auto-generated method stub
      return false;
    }
}

And the following is the line I'm using to launch the new activity:

Intent i = new Intent(getApplicationContext(), GoogleMapsActivity.class);
startActivity(i);

I have checked my class GoogleMapsActivity.java, the file is present and the spelling/wording all match.

I suspect the error may be caused by my AndroidManifest.xml, but I cannot find the problem.

Could someone please point me in the right direction?

you are definitely missing to add one jar file so that the Noclassdeffound error will show. and if u have add all jar file even then this error comes then i give you one best answer that definitely works. just create libs folder in ur project and add all jar file in libs folder and your problem definitely solves out.

Be sure that the <uses-library android:name="com.google.android.maps"/> is right location .
